3 GENERAL DESCRIPTION
The PCF2116 family of LCD controller/drivers consists of the PCF2116x, the PCF2114x and the PCF2116K. The term ‘PCF2116’ is used to refer to all devices for common information. Specific information is given in separate paragraphs.
The ‘x’ in ‘PCF2116x’ and ‘PCF2114x’ represents a specific letter code for a character set in the character generator ROM (CGROM). The different character sets currently available are specified by the letters A, C, and G (see Figs 8 to 10). Other character sets are available on request.
The PCF2116 is a low-power CMOS LCD controller and driver, designed to drive a split screen dot matrix LCD display of 1 or 2 lines by 24 characters or 2 or 4 lines by 12 characters with 5 × 8 dot format. All necessary functions for the display are provided in a single chip, including on-chip generation of LCD bias voltages, resulting in a minimum of external components and lower system power consumption. The chip contains a character generator and displays alphanumeric and kana (Japanese) characters. The PCF2116 interfaces to most microcontrollers via a 4 or 8-bit bus or via the 2-wire
2
I
C-bus. To allow partial VDD shutdown the ESD protection system of the SCL and SDA pins does not use a diode connected to VDD.
The PCF2116K differs from the other members of the family in that:
V
LCD/VOP
generation is different (see Section 8.1)
It is available with character set C only (see Fig.9).

7 PIN FUNCTIONS
7.1 RS: register select (parallel control)
RS selects the register to be accessed for read and write when the device is controlled by the parallel interface. RS = logic 0 selects the instruction register for write and the Busy Flag and Address Counter for read. RS = logic 1 selects the data register for both read and write. There is an internal pull-up on pin RS.
7.2 R/
W: read/write (parallel control)
R/W selects either the read (R/W = logic 1) or write (R/W = logic 0) operation when control is by the parallel interface. There is an internal pull-up on this pin.
7.3 E: data bus clock
The E pin is set HIGH to signal the start of a read or write operation when the device is controlled by the parallel interface. Data is clocked in or out of the chip on the negative edge of the clock. Note that this pin must be tied to logic 0 (V
) when I2C-bus control is used.
SS
7.4 DB0 to DB7: data bus
The bidirectional, 3-state data bus transfers data between the system controller and the PCF2116. DB7 may be used as the Busy Flag, signalling that internal operations are not yet completed. In 4-bit operations the 4 higher order lines DB4 to DB7 are used; DB0 to DB3 must be left open circuit. There is an internal pull-up on each of the data lines. Note that these pins must be left open circuit when
2
I
C-bus control is used.
7.5 C1 to C60: column driver outputs
These pins output the data for pairs of columns. This arrangement permits optimized chip-on-glass (COG) layout for 4-line by 12 characters.
7.6 R1 to R32: row driver outputs
These pins output the row select waveforms to the left and right halves of the display.

8 FUNCTIONAL DESCRIPTION (see Fig.1)
8.1 LCD supply voltage generator, PCF2114x and PCF2116x
The on-chip voltage generator is controlled by bit G of the ‘Function set’ instruction and V
.
0
V0 is a high-impedance input and draws no current from the system power supply. Its range is between VSS and VDD− 1 V. When V0 is connected to VDD the generator is switched off and an external voltage must be supplied to pin V
. This may be more negative than VSS.
LCD
When G = logic 1 the generator produces a negative voltage at pin V
, controlled by the input voltage at
LCD
pin V0. The LCD operating voltage is given by the relationship:
VOP= 1.8VDD− V
0
Where:
VOP=VDD− V V
LCD=V0
When G = logic 0, the generated output voltage V

(0.8VDD)

is
equal to V0 (between VSS and VDD). In this instance:

LCD controller/drivers PCF2116 family
8.2 LCD supply voltage generator, PCF2116K
In the PCF2116K version, V0 is connected through an on-chip resistor (R0) to V
. Resistor R0 has a nominal
LCD
value of 1 M and draws a typical current of 4 µA from the pin V0. A constant voltage (equal to 1.34VDD) is always present across R0.
The voltage range of the PCF2116K is between VSS and VDD− 0.5 V (see Fig.4). When V0 is connected to VDD the generator is switched off and an external voltage must be supplied to pin V
. This may be more negative than VSS.
LCD
When G = logic 1 the generator produces a negative voltage at pin V
, controlled by the input voltage at
LCD
pin V0. The LCD operating voltage is given by the relationship:
VOP= 2.34VDD− V
0
Where:
VOP=VDD− V V
LCD=V0
When G = logic 0, the generated output voltage V
LCD
(1.34VDD)
LCD
is
equal to V0 (between VSS and VDD). In this instance:
VOP=VDD− V
0
8.3 Character generator ROM (CGROM)
The standard character sets A, C and G are available for the PCF2114x and PCF2116x. Standard character set C is available for the PCF2116K.
8.4 LCD bias voltage generator
The intermediate bias voltages for the LCD display are also generated on-chip. This removes the need for an external resistive bias chain and significantly reduces the system power consumption. The optimum levels depend on the multiplex rate and are selected automatically when the number of lines in the display is defined.
The optimum value of V
depends on the multiplex rate,
OP
the LCD threshold voltage (Vth) and the number of bias levels and is given by the relationships in Table 1.Using a 5-level bias scheme for 1 : 16 MUX rate allows VOP<5V for most LCD liquids. The effect on the display contrast is negligible.
8.5 Oscillator
The on-chip oscillator provides the clock signal for the display system. No external components are required. Pin OSC must be connected to VDD.
8.6 External clock
If an external clock is to be used, it must be input at pin OSC. The resulting display frame frequency is given by f
frame
=1⁄
2304fosc
. A clock signal must always be present,
otherwise the LCD may be frozen in a DC state.
8.7 Power-on reset
The power-on reset block initializes the chip after power-on or power failure.
8.8 Registers
The PCF2116 has two 8-bit registers, an Instruction Register (IR) and a Data Register (DR). The Register Select signal (RS) determines which register will be accessed.
The instruction register stores instruction codes such as ‘Display clear’ and ‘Cursor shift’, and address information for the Display Data RAM (DDRAM) and Character Generator RAM (CGRAM). The instruction register can be written to, but not read, by the system controller.
The data register temporarily stores data to be read from the DDRAM and CGRAM. When reading, data from the DDRAM or CGRAM corresponding to the address in the Address Counter is written to the data register prior to being read by the ‘Read data’ instruction.
8.9 Busy Flag
The Busy Flag indicates the free/busy status of the PCF2116. Logic 1 indicates that the chip is busy and further instructions will not be accepted. The Busy Flag is output to pin DB7 when RS = logic 0 and R/
W = logic 1. Instructions should only be written after checking that the Busy Flag is logic 0 or waiting for the required number of clock cycles.

8.10 Address Counter (AC)
The Address Counter assigns addresses to the DDRAM and CGRAM for reading and writing and is set by the instructions ‘Set CGRAM address’ and ‘Set DDRAM address’. After a read/write operation the Address Counter is automatically incremented or decremented by 1.The Address Counter contents are output to the bus (DB0 to DB6) when RS = logic 0 and R/W = logic 1.
8.11 Display data RAM (DDRAM)
The display data RAM stores up to 80 characters of display data represented by 8-bit character codes. RAM locations not used for storing display data can be used as general purpose RAM. The basic DDRAM-to-display mapping scheme is shown in Fig.5. With no display shift the characters represented by the codes in the first 12 or 24 RAM locations starting at address 00 in line 1 are displayed. Subsequent lines display data starting at addresses 20, 40, or 60 Hex. Figs 6 and 7 show the DDRAM-to-display mapping principle when the display is shifted.
The address range for a 1-line display is 00 to 4F; for a 2-line display from 00 to 27 (line 1) and 40 to 67 (line 2); for a 4-line display from 00 to 13, 20 to 33, 40 to 53 and 60 to 73 for lines 1, 2, 3 and 4 respectively. For 2 and 4-line displays the end address of one line and the start address of the next line are not consecutive. When the display is shifted each line wraps around independently of the others (Figs 6 and 7).
When data is written into the DDRAM wrap-around occurs from 4F to 00 in 1-line mode and from 27 to 40 and 67 to 00 in 2-line mode; from 13 to 20, 33 to 40, 53 to 60 and 73 to 00 in 4-line mode.
8.13 Character generator RAM (CGRAM)
Up to 16 user-defined characters may be stored in the character generator RAM. The CGROM and CGRAM use a common address space, of which the first column is reserved for the CGRAM (see Fig.8). Figure 11 shows the addressing principle for the CGRAM.
8.14 Cursor control circuit
The cursor control circuit generates the cursor (underline and/or character blink as shown in Fig.12) at the DDRAM address contained in the Address Counter. When the Address Counter contains the CGRAM address the cursor will be inhibited.
8.15 Timing generator
The timing generator produces the various signals required to drive the internal circuitry. Internal chip operation is not disturbed by operations on the data buses.
8.16 LCD row and column drivers
The PCF2116 contains 32 row and 60 column drivers, which connect the appropriate LCD bias voltages in sequence to the display, in accordance with the data to be displayed. The bias voltages and the timing are selected automatically when the number of lines in the display is selected. Figures 13 and 14 show typical waveforms.
In 1-line mode (1 : 16) the row outputs are driven in pairs: R1/R17, R2/R18 for example. This allows the output pairs to be connected in parallel, providing greater drive capability.
Unused outputs should be left unconnected.
8.12 Character generator ROM (CGROM)
The character generator ROM generates 240 character patterns in 5 × 8 dot format from 8-bit character codes. Figures 8 to 10 show the character sets currently available.

Character code bits 0to 3 correspond to CGRAM address bits 3 to 6. CGRAM address bits 0 to 2 designate character pattern line position. The 8th line is the cursor position and display is performed by logical OR with
the cursor. Data in the 8th line will appear in the cursor position. Character pattern column positions correspond to CGRAM data bits 0 to 4, as shown in Fig.11 (bit 4 being at the left end). As shown in Figs 8 and 11, CGRAM character patterns are selected when character code bits 4 to 7 are all logic 0. CGRAM data = logic 1
corresponds to selection for display. Only bits 0 to 5 of the CGRAM address are set by the ‘Set CGRAM address’ instruction. Bit 6 can be set using the ‘Set DDRAM address’ instruction
or by using the auto-increment feature during CGRAM write. All bits 0 to 6 can be read using the ‘Read busy flag and address’ instruction.

8.18 Programming MUX 1 : 32 displays with the PCF2114x
To drive a 2-line by 24 characters MUX 1 : 32 display, use instruction ‘Function set’ M, N to 0, 1. Note that the right half of the display needs mirrored column connection compared to a display driven by a PCF2116x.
To drive a 4-line by 12 characters MUX 1 : 32 display the PCF2116x operating instructions apply. There is no functional difference between the PCF2114x and the PCF2116x in this mode. For such an application set M, N to 1, 1 with the ‘Function set’ instruction.
8.19 Reset function
The PCF2116 automatically initializes (resets) when power is turned on. After reset the chip has the following state.

9 INSTRUCTIONS
Only two PCF2116 registers, the Instruction Register (IR) and the Data Register (DR) can be directly controlled by the microcontroller. Before internal operation, control information is stored temporarily in these registers to allow interface to various types of microcontrollers which operate at different speeds or to allow interface to peripheral control ICs. The PCF2116 operation is controlled by the instructions shown in Table 3 together with their execution time. Details are explained in subsequent sections.
Instructions are of 4 categories, those that:
1. Designate PCF2116 functions such as display format, data length, etc.
2. Set internal RAM addresses
3. Perform data transfer with internal RAM
4. Others.
In normal use, category 3 instructions are used most frequently. However, automatic incrementing by 1 (or decrementing by 1) of internal RAM addresses after each data write lessens the microcontroller program load. The display shift in particular can be performed concurrently with display data write, enabling the designer to develop systems in minimum time with maximum programming efficiency.
During internal operation, no instruction other than ‘Read busy flag and address’ will be executed.
Because the Busy Flag is set to logic 1 while an instruction is being executed, check to make sure it is on logic 0 before sending the next instruction or wait for the maximum instruction execution time, as given in Table 3. An instruction sent while the Busy Flag is HIGH will not be executed.

9.1 Clear display
‘Clear display’ writes space code 20 (hexadecimal) into all DDRAM addresses (The character pattern for character code 20 must be blank pattern). Sets the DDRAM Address Counter to logic 0. Returns display to its original position if it was shifted. Thus, the display disappears and the cursor or blink position goes to the left edge of the display (the first line if 2 or 4 lines are displayed). Sets entry mode I/D = logic 1 (increment mode). S of entry mode does not change.
The instruction ‘Clear display’ requires extra execution time. This may be allowed for by checking the busy-flag (BF) or by waiting until 2 ms has elapsed. The latter must be applied where no read-back options are foreseen, as in some chip-on-glass (COG) applications.
9.2 Return home
‘Return home’ sets the DDRAM Address Counter to logic 0. Returns display to its original position if it was shifted. DDRAM contents do not change. The cursor or blink position goes to the left of the display (the first line if 2 or 4 lines are displayed). I/D and S of entry mode do not change.
9.3 Entry mode set
9.3.1 I/D When I/D = logic 1 (0) the DDRAM or CGRAM address
increments (decrements) by 1 when data is written into or read from the DDRAM or CGRAM. The cursor or blink position moves to the right when incremented and to the left when decremented. The cursor and blink are inhibited when the CGRAM is accessed.
9.3.2 S When S = logic 1, the entire display shifts either to the right
(I/D = logic 0) or to the left (I/D = logic 1) during a DDRAM write. Thus it looks as if the cursor stands still and the display moves. The display does not shift when reading from the DDRAM, or when writing into or reading out of the CGRAM. When S = logic 0 the display does not shift.
9.4.2 C The cursor is displayed when C = logic 1 and inhibited
when C = logic 0. Even if the cursor disappears, the display functions I/D, etc. remain in operation during display data write. The cursor is displayed using 5 dots in the 8thline (see Fig.12).
9.4.3 B The character indicated by the cursor blinks when
B = logic 1. The blink is displayed by switching between display characters and all dots on with a period of 1 second when f frequencies the blink period is equal to 150 kHz/f
= 150 kHz (see Fig.12). At other clock
osc
osc
. The cursor and the blink can be set to display simultaneously.
9.5 Cursor/display shift
‘Cursor/display shift’ moves the cursor position or the display to the right or left without writing or reading display data. This function is used to correct a character or move the cursor through the display. In 2 or 4-line displays, the cursor moves to the next line when it passes the last position (40 or 20 decimal) of the line. When the displayed data is shifted repeatedly all lines shift at the same time; displayed characters do not shift into the next line. The Address Counter (AC) content does not change if the only action performed is shift display, but increments or decrements with the cursor shift.
9.6 Function set
9.6.1 DL (
PARALLEL MODE ONLY)
Defines interface data width when the parallel data interface is used.
Data is sent or received in bytes (bits DB7 to DB0) when DL = logic 1, or in two 4-bit nibbles (DB7 to DB4) when DL = logic 0. When 4-bit width is selected, data is transmitted in two cycles using the parallel bus
(1)
.
When using the I2C-bus interface the DL should not previously have been set to 0 using the parallel interface.
9.4 Display on/off control
9.4.1 D The display is on when D = logic 1 and off when
D = logic 0. Display data in the DDRAM are not affected and can be displayed immediately by setting D to logic 1.

9.6.2 N, M Sets number of display lines.
(1) In a 4-bit application DB3 to DB0 are left open (internal
pull-ups). Hence in the first ‘Function set’ instruction after power-on, G and H are set to 1. A second ‘Function set’ must then be sent (2 nibbles) to set G and H to their required values.

9.7 Set CGRAM address
‘Set CGRAM address’ sets bit 0 to 5 of the CGRAM address (A
in Table 3) into the Address Counter
CG
(binary A[5] to A[0]). Data can then be written to or read from the CGRAM.
Only bits 0 to 5 of the CGRAM address are set by the ‘Set CGRAM address’ instruction. Bit 6 can be set using the ‘Set DDRAM address’ instruction or by using the auto-increment feature during CGRAM write. All bits 0 to 6 can be read using the ‘Read busy flag and address’ instruction.
9.8 Set DDRAM address
‘Set DDRAM address’ sets the DDRAM address (A
DD
in Table 3) into the Address Counter (binary A[6] to A[0]). Data can then be written to or read from the DDRAM.
Hexadecimal address ranges.

4-line by 12; 21 14x/2116x
and 60 to 73
9.9 Read busy flag and address
‘Read busy flag and address’ reads the Busy Flag (BF). BF = logic 1 indicates that an internal operation is in progress. The next instruction will not be executed until BF = logic 0, so BF should be checked before sending another instruction.
At the same time, the value of the Address Counter (A
in
C
Table 3) expressed in binary A[6] to A[0] is read out. The Address Counter is used by both CGRAM and DDRAM, and its value is determined by the previous instruction.
9.10 Write data to CGRAM or DDRAM
Writes binary 8-bit data D[7] to D[0] to the CGRAM or the DDRAM.
Whether the CGRAM or DDRAM is to be written into is determined by the previous specification of CGRAM or DDRAM address setting.
After writing, the address automatically increments or decrements by 1, in accordance with the entry mode. Only bits D[4] to D[0] of CGRAM data are valid, bits D[7] to D[5] are ‘don’t care’.
9.11 Read data from CGRAM or DDRAM
Reads binary 8-bit data D[7] to D[0] from the CGRAM or DDRAM.
The most recent ‘Set address’ instruction determines whether the CGRAM or DDRAM is to be read.
The ‘Read data’ instruction gates the content of the data register (DR) to the bus while E = HIGH. After E goes LOW again, internal operation increments (or decrements) the AC and stores RAM data corresponding to the new AC into the DR.
Remark: the only three instructions that update the data register (DR) are:
‘Set CGRAM address’
‘Set DDRAM address’
‘Read data’ from CGRAM or DDRAM.
Other instructions (e.g. ‘Write data’, ‘Cursor/Display shift’, ‘Clear display’, ‘Return home’) will not modify the data register content.
10 INTERFACE TO MICROCONTROLLER
(PARALLEL INTERFACE)
The PCF2116 can send data in either two 4-bit operations or one 8-bit operation and can thus interface to 4-bit or 8-bit microcontrollers.
In 8-bit mode data is transferred as 8-bit bytes using the 8 data lines DB0 to DB7. Three further control lines E, RS, and R/
W are required.
In 4-bit mode data is transferred in two cycles of 4-bits each. The higher order bits (corresponding to DB4 to DB7 in 8-bit mode) are sent in the first cycle and the lower order bits (DB0 to DB3 in 8-bit mode) in the second. Data transfer is complete after two 4-bit data transfers. It should be noted that two cycles are also required for the Busy Flag check. 4-bit operation is selected by instruction. See Figs 18, 19 and 20 for examples of bus protocol.
In 4-bit mode pins DB3 to DB0 must be left open-circuit. They are pulled up to VDD internally.

11 INTERFACE TO MICROCONTROLLER

C-BUS INTERFACE)
(I
2
11.1 Characteristics of the I
C-bus
The I2C-bus is for bidirectional, two-line communication between different ICs or modules. The two lines are a serial data line (SDA) and a serial clock line (SCL). Both lines must be connected to a positive supply via a pull-up resistor. Data transfer may be initiated only when the bus is not busy.
11.2 Bit transfer
One data bit is transferred during each clock pulse. The data on the SDA line must remain stable during the HIGH period of the clock pulse as changes in the data line at this time will be interpreted as a control signal.
11.3 START and STOP conditions
Both data and clock lines remain HIGH when the bus is not busy. A HIGH-to-LOW transition of the data line, while the clock is HIGH is defined as the START condition (S). A LOW-to-HIGH transition of the data line while the clock is HIGH is defined as the STOP condition (P).
11.4 System configuration
A device generating a message is a ‘transmitter’, a device receiving a message is the ‘receiver’. The device that controls the message is the ‘master’ and the devices which are controlled by the master are the ‘slaves’.
11.5 Acknowledge
The number of data bytes transferred between the START and STOP conditions from transmitter to receiver is unlimited. Each byte of eight bits is followed by an acknowledge bit. The acknowledge bit is a HIGH level signal put on the bus by the transmitter during which time the master generates an extra acknowledge related clock pulse. A slave receiver which is addressed must generate an acknowledge after the reception of each byte. Also a master receiver must generate an acknowledge after the reception of each byte that has been clocked out of the slave transmitter. The device that acknowledges must pull-down the SDA line during the acknowledge clock pulse, so that the SDA line is stable LOW during the HIGH period of the acknowledge related clock pulse (set-up and hold times must be taken into consideration). A master receiver must signal an end of data to the transmitter by not generating an acknowledge on the last byte that has been clocked out of the slave. In this event the transmitter must leave the data line HIGH to enable the master to generate a STOP condition.
11.6 I
2
C-bus protocol
Before any data is transmitted on the I2C-bus, the device which should respond is addressed first. The addressing is always carried out with the first byte transmitted after the start procedure. The I2C-bus configuration for the different PCF2116 READ and WRITE cycles is shown in Figs 25 to 27.

18.1 8-bit operation, 1-line display using internal
reset
Table 6 shows an example of a 1-line display in 8-bit operation. The PCF2116 functions must be set by the ‘Function set’ instruction prior to display. Since the display data RAM can store data for 80 characters, the RAM can be used for advertising displays when combined with display shift operation. Since the display shift operation changes display position only and DDRAM contents remain unchanged, display data entered first can be displayed when the Return Home operation is performed.
18.2 4-bit operation, 1-line display using internal
reset
The program must set functions prior to 4-bit operation. Table 5 shows an example. When power is turned on, 8-bit operation is automatically selected and the PCF2116 attempts to perform the first write as an 8-bit operation. Since nothing is connected to DB0 to DB3, a rewrite is then required. However, since one operation is completed in two accesses of 4-bit operation, a rewrite is required to set the functions (see Table 5 step 3).
Thus, DB4 to DB7 of the function set are written twice.
18.3 8-bit operation, 2-line display
For a 2-line display, the cursor automatically moves from the first to the second line after the 40th digit of the first line has been written. Thus, if there are only 8 characters in the first line, the DDRAM address must be set after the eighth character is completed (see Table 7). Note that both lines of the display are always shifted together; data does not shift from one line to the other.

18.4 I
C operation, 1-line display
A control byte is required with most instructions (see Table 8).
18.5 Initializing by instruction
If the power supply conditions for correctly operating the internal reset circuit are not met, the PCF2116 must be initialized by instruction. Tables 9 and 10 show how this may be performed for 8-bit and 4-bit operation.

21 SOLDERING
21.1 Introduction
There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and surface mounted components are mixed on one printed-circuit board. However, wave soldering is not always suitable for surface mounted ICs, or for printed-circuits with high population densities. In these situations reflow soldering is often used.
This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in
“IC Package Databook”
our
21.2 Reflow soldering
Reflow soldering techniques are suitable for all LQFP packages.
Reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement.
Several techniques exist for reflowing; for example, thermal conduction by heated belt. Dwell times vary between 50 and 300 seconds depending on heating method. Typical reflow temperatures range from 215 to 250 °C.
Preheating is necessary to dry the paste and evaporate the binding agent. Preheating duration: 45 minutes at 45 °C.
21.3 Wave soldering
Wave soldering is not recommended for LQFP packages. This is because of the likelihood of solder bridging due to closely-spaced leads and the possibility of incomplete solder penetration in multi-lead devices.
(order code 9398 652 90011).
If wave soldering cannot be avoided, the following conditions must be observed:
A double-wave (a turbulent wave with high upward
pressure followed by a smooth laminar wave) soldering technique should be used.
The footprint must be at an angle of 45° to the board
direction and must incorporate solder thieves downstream and at the side corners.
Even with these conditions, do not consider wave soldering LQFP packages LQFP48 (SOT313-2), LQFP64 (SOT314-2) or LQFP80 (SOT315-1).
During placement and before soldering, the package must be fixed with a droplet of adhesive. The adhesive can be applied by screen printing, pin transfer or syringe dispensing. The package can be soldered after the adhesive is cured.
Maximum permissible solder temperature is 260 °C, and maximum duration of package immersion in solder is 10 seconds, if cooled to less than 150 °C within 6 seconds. Typical dwell time is 4 seconds at 250 °C.
A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications.
21.4 Repairing soldered joints
Fix the component by first soldering two diagonally­opposite end leads. Use only a low voltage soldering iron (less than 24 V) applied to the flat part of the lead. Contact time must be limited to 10 seconds at up to 300 °C. When using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 °C.
