LCD Segment / Common Driver with Controller for Character Display System

CMOS

GENERAL DESCRIPTION

SSD1801 is a single-chip CMOS LCD driver with controller for liquid crystal dot-matrix character display system. It consists of 105 high voltage driving output pins for driving 80 Segments, 24 Commons and 1 icon driving-Common. It can display 2 or 3 lines of 16 characters with 5x8 dots format. The double height character mode and line vertical scroll functions are supported.

SSD1801 displays character directly from its internal 10,240 bits (256 characters x 5 x 8 dots) Character Generator ROM (CGROM). All the character codes are stored in the 512 bits (16 character x 4 lines) Data Display RAM (DDRAM). User defined character can be loaded via 320 bits (8 characters x 5 x 8 dots) Character Generator RAM (CGRAM). In addition, there is a 80 bits Icon RAM for Icon display. Data/ Commands are sent from general MCU through a software selectable 6800-/8080-series compatible 4/ 8-bit Parallel Interface or Serial Peripheral Interface.

SSD1801 embeds a DC-DC Converter, Voltage Regulator, Voltage divider and RC oscillator which reduce the number of external components. With the special design on minimizing power consumption and die size, SSD1801 is suitable for portable battery-driven applications requiring a long operation period and a compact size.

FUNCTIONAL BLOCK DESCRIPTIONS

Command Decoder and Command Interface

This module determines whether the input data is interpreted as data or command. Data is directed to this module

based upon the input of the D/

ICONRAM). If D/ the corresponding command register.

C is low, the input at D7-D0 is interpreted as a Command and it will be decoded and be written to

MPU Parallel 6800-series Interface in 8 bits bus mode

The parallel interface consists of 8 bi-directional data pins (D7-D0), R/W(WR ), D/ C, E(RD ), CS . R/W(WR )

input high indicates a read operation from the internal RAM (DDRAM, CGRAM and ICONRAM). R/ indicates a write operation to internal RAM (DDRAM, CGRAM and ICONRAM) or Internal Command Registers

depending on the status of D/

CS are low. Refer to Figure 20 for Parallel Interface Timing Diagram of 6800-series microprocessors.

In order to match the operating frequency of display RAM with that of the microprocessor, some pipeline processings are internally performed which require the insertion of a dummy read before the first actual display data read. This is shown in Figure 4 below. The dummy read make the address counter (AC) increased by 1. So it is recommended to set address again before writing. The consecutive read after the dummy read are also the valid data. The instruction read cycle is not supported and it is regarded as a no operation cycle.

MPU Parallel 8080-series Interface in 8 bits bus mode

The parallel interface consists of 8 bi-directional data pins (D7-D0), R/W(WR ), D/ C, E(RD ), CS . E( RD ) input

serves as data read latch signal (clock) when low provided that

RAM read/ write is controlled by D/

CS is low. Refer to Figure 21 for Parallel Interface Timing Diagram of 8080-series microprocessor.

that Similar to 6800-series interface, a dummy read is also required before the first actual display data read.

4-bit MPU Parallel 6800/8080-Series Interface

The control of 4-bit bus mode is exactly the same as 8-bit bus mode except 2 consecutive access (read/ write) is needed to read/ write 8 bits data. For write operation, upper order bits are written before the low order bits, and low order bits are always read before the upper order bit in read transaction.

MPU Serial Interface

The serial interface consists of serial clock SCK (D6), serial data SDA (D7), D/C, CS . SDA is shifted into a 8-bit

shift register on every rising edge of SCK in the order of D determine whether the data byte in the shift register is written to the internal RAM (DDRAM, CGRAM, ICONRAM) or

command register at the same clock.

Oscillator Circuit

This module is an On-Chip low power RC oscillator circuitry. The oscillator generates the clock for the DC-DC voltage converter. This clock is also used in the Display Timing Generator.

ADDRESS COUNTER (AC)

Address Counter (AC) in SSD1801 stores DDRAM/ CGRAM/ ICONRAM address. After writing into or reading from DDRAM/ CGRAM/ ICONRAM. AC is automatically increased by 1. There is only one address counter and stores the address among DDRAM / CGRAM / ICONRAM.

Display Data Latch

A series of registers carrying the display signal information. For SSD1801, there are 105 latches (80 + 25) for holding the data, which will be fed to the HV Buffer Cell and Level Selector to output the required voltage levels.

Level Selector

Level Selector is a control of the display synchronization. Display voltage can be separated into two sets and used with different cycles. Synchronization is important since it selects the required LCD voltage level to the HV Buffer Cell, which in turn outputs the COM or SEG LCD waveform.

HV Buffer Cell (Level Shifter)

Buffer Cell work as a level shifter which translates the low voltage output signal to the required driving voltage. The output is shifted out with an internal FRM clock which comes from the Display Timing Generator. The voltage levels are given by the level selector which is synchronized with the internal M signal.

COMMAND DESCRIPTIONS

Return Home

Return Home instruction field makes cursor return home. DDRAM address is set to 00h from address counter and the cursor returns to 00h position. The contents of DDRAM are not changed.

Set Double Height Mode

This command increases the height of one character line from 8 to 16 dots. If the number of COM signal needed exceeds the existing COM signal (COM0-COM15 for 2-line mode, COM0-COM23 for 3-line mode), the last character line will not be displayed. It will happen at following cases:

1. 3-line mode, X The 3rd line will not be displayed.

2. 3-line mode, X The 3rd line will be displayed.

3. 2-line mode, X1X0 = 01 where COM0-COM15 is double height.

The 2nd line will not be displayed.

1X0 = 01 where COM0-COM15 is double height, COM16-COM23 is normal.

1X0 = 10 where COM0-COM7 is normal, COM8-COM23 is double height.

Set Power Save Mode / Oscillator Control

To enter Standby or Sleep Mode, it should be done by turning off the internal oscillator and turning on the power save control bit. The corresponding control bits are X mode, internal voltage converter, voltage regulator and voltage divider should also be turned off by using Power Control Register. After putting the system into power save mode, the following status will be entered:

1. Internal oscillator and LCD power supply circuits are stopped.

2. Segment and Common drivers output AV

3. The display data and operation mode before sleep are held. All the internal circuit are stopped.

Function Set

This command sets 3 functions on the system. They are the number of display line (2 or 3), COM shift direction (left or right) and CGROM/ CGRAM character area select.

Set Display Start Line

This command is to set Display Start Line register to determine starting address of display data RAM to be displayed by selecting a value from 0 to 3. With the value equals to 0, the display will start from address (00h-0Fh). With the value equals to 1, the display will start from address (10h-1Fh). With the value equals to 2, the display will start from address (20h-2Fh). With the value equals to 3, the display will start from address (30-3Fh).

Set Bias Control

Bias ratio 1/4 or 1/5 could be set using this command. When changing the number of line display, the bias ratio also needs to be adjusted to make display contrast consistent.

Set Power Control Register

This command turns on / off the various power circuits associated with the chip which including regulated DC-DC converter and voltage divider.

Set Display Control

This command provides 3 display functions. It turns on/off both the cursor, blink and display. When both cursor and blink control bit set high, the driver make LCD alternate between inverting display character and normal display character at the cursor position with about a half second. On the contrary, if cursor control bit is low, only a normal character is displayed regardless of blink control bit.
