the internal reset is active for a period of td (typically

Considering the VDD rise time, the following measures for
a correct Power-on-reset can be taken:

• If the VDD rises above the minimum operation voltage
before time period t

is exceeded, no external

components are necessary (see Fig.6).

• If V

has a slow rise time, such that after the time

external components are required (see Figs 4 and 7).

8 ANALOG CONTROL

8.1 6-bit PWM DACs

Five PWM outputs are available for analog control
purposes e.g. volume, balance, brightness, saturation, etc.
The block diagram of a typical 6-bit PWM DAC is shown in
Fig.8. Each PWM output can generate pulses of
programmable length that have a repetition frequency of

IN SELECTION FOR PWM OUTPUTS

PWM

XTAL

.

The PWM outputs PWM1 to PWM5, share the same pins
as the Derivative Port lines DP0.1 to DP0.5.

Setting the (relevant PWM enable) bit PWMnE to:

• Logic 1, selects the relevant PWMx output function

• Logic 0, selects the relevant DP0.x Port function.

8.1.2 P

OLARITY OF THE PWM OUTPUTS

The polarity of all five PWM outputs is selected by the state
of the polarity control bit P6LVL.

Setting the control bit P6LVL to:

• Logic 0, sets the PWMx outputs to the default polarity

• Logic 1, inverts all the PWMx outputs.

8.1.3 A

NALOG OUTPUT VOLTAGE

A DC voltage proportional to the PWM control setting may
be obtained by connecting an integrating network to each
of the PWM outputs (see Fig.9).

The analog value is calculated as follows:

9 VST CONTROL

9.1 14-bit PWM DAC

The PCA84C640 has one 14-bit PWM DAC output (TDAC)
with a resolution of 16384 levels for Voltage Synthesized
Tuning. The PWM DAC (see Fig.10) consists of:

• 14-bit counter

• Two 7-bit DAC interface data latches (VSTH and VSTL)

• One 14-bit DAC data latch (VSTREG)

• Pulse control.

The polarity of output TDAC is selected with bit P14LVL.
Setting the bit P14LVL to:

• Logic 1, sets the TDAC output to the default polarity

• Logic 0, inverts the TDAC output.

ATA AND INTERFACE LATCHES

128==

In order to ensure correct operation, interface data latch
VSTH is loaded first and then interface data latch VSTL.
The contents of:

• VSTH are used for coarse adjustment

• VSTL are used for fine adjustment.

9.2 Coarse adjustment

The coarse adjustment output (OUT1) is reset to LOW
(inactive) at the start of each t
It will remain LOW until the time has

period.

sub

t0VSTH 1+()×[]
elapsed and then will go HIGH and remain so until the next
t

period starts.

sub

9.3 Fine adjustment

Fine adjustment is achieved by generating additional
pulses at the start of particular sub-periods (t

subn

).
These additional pulses have a width of t0.
The sub-period in which a pulse is added is determined by
the contents of VSTL interface latch.
Table 3 gives the numbers of the t

, at the start of which

subn

an additional pulse is generated, depending on the bit in
VSTL being a logic 0. When more than one bit is a logic 0
a combination of additional pulses are generated.
For example, if VSTL = 1111010, which is a combination
of

• VSTL = 1111110: sub-period 64, and

• VSTL = 1111011: sub-periods 16, 48, 80 and 112,

then additional pulses will be given in sub-periods
16, 48, 64, 80 and 112; this is illustrated in Fig.12.

If VSTH = 0011101, VSTL = 1111010 and P14LVL = 0,
then the TDAC output is as shown in Fig.13.

0111111 1, 3, 5, 7, 9, 11, 13, 15, 17, .... 125, 127

At the beginning of the first t

period following the loading

sub

of VSTL, both data latches are loaded into data latch
VSTREG. After the contents of VSTH and VSTL are
latched into VSTREG, one t

period is needed to

sub

generate the appropriate pulse pattern.
To ensure correct DAC conversion, two (2) t

periods

sub

should be allowed before beginning the next sequence.

10 AFC INPUT

The AFC input is used to measure the level of the
Automatic Frequency Control signal. This is achieved by
comparing the AFC input signal with the output of a 3-bit
DAC as shown in Fig.14. DAC analog switches select one
of 8 resistor taps connected between VDD and VSS.
Consequently, eight different voltages may be selected
(see Table 4). The compare signal AFCC, can be tested to
determine whether the AFC input is higher or lower than
the DAC level.

The AFC input shares the same pin as the Derivative Port
line DP1.7. Setting the enable bit AFCE to:

• Logic 1, selects the AFC function

• Logic 0, selects the Derivative Port DP1.7 function.

12 ON SCREEN DISPLAY

12.1 Features

• Display format: 2 rows × 16 characters

• Software controlled vertical and horizontal display

position

• 64 different (mask programmable) characters in ROM

• Black box background

• Four programmable display character sizes

• Four programmable character dot matrix sizes:

–6×9 and 6 × 13
–8×9 and 8 × 13

• Half-dot rounding for the whole screen

• 4 from 7 colours possible on screen

• Clock generator for On Screen Display function with:

– RC oscillator
– LC oscillator,
for the various types of PCA84C44X; 84C64X; 84C84X.

12.2 Horizontal display position control

The horizontal position counter is incremented every OSD
cycle after the programmed level of HSYNCN occurs at the
HSYNCN pin. The counter is reset when the opposite
polarity of the HSYNCN pulse is reached.

12.4 Clock generator

There are two types of oscillators available for the various
types. The oscillator is triggered on the trailing edge of
HSYNCN when the OSD logic is enabled and stops on the
following leading edge of HSYNCN.

The OSD oscillator must be externally adjusted to the
desired frequency (decreasing the OSD frequency gives
broader characters). Before the oscillation frequency can
be adjusted HSYNCN must be HIGH (if HLVL = 1).
Oscillation stops by setting the HSYNCN pin LOW when
HLVL = 1.

12.4.1 RC
The RC oscillator is available in the types:

PCA84C440; 84C443; 84C640; 84C643;
84C840; 84C843.

The external RC network is connected between
pin 28 and VSS (see Fig.19).

12.4.2 LC
The LC oscillator is available in the types:

PCA84C441; 84C444; 84C641; 84C644;
84C841; 84C844.

The external LC network is connected between
pins 28 and 29 (see Fig.20).

12.7 OSD display position

12.7.1 V

ERTICAL POSITION

The line number of the vertical start position for:

• Row 0 is 4 × (VP00 → VP05)

• Row 1 is 4 × (VP10 → VP15).

Where:

• (VP00 → VP05) = the decimal value of VP00 → VP05

• (VP10 → VP15) = the decimal value of VP10 → VP15.

The character height in:

• Row 0 is H0 and is a function of the number of dots per
character and the state of the size control bits
SZ00 and SZ01

• Row 1 is H1 and is a function of the number of dots per
character and the state of the size control bits
SZ10 and SZ11.

Row 0 and Row 1 must not overlap each other and
therefore: VP1 ≥ (VP0 + H0); see Fig.25.

The four possible character heights are shown in Table 23.

12.7.2 H

ORIZONTAL POSITION

The horizontal start position (HP) of,

• Row 0: HP0 = 4 × (HP00 → HP05) + 5 × t

• Row 1: HP1 = 4 × (HP10 → HP15) + 5 × t

Where:

• (HP00 → HP05) = the decimal value of HP00 → HP05

• (HP10 → HP15) = the decimal value of HP10 → HP15
and (HP10 → HP15) > 10

12.9 Character ROM

Character ROM contains the dot character fonts.
13 × 8 dots are reserved for each character, regardless of
the dot matrix size actually selected.
The dot matrix grid is shown in Fig.28.

Philips provides a software under MS DOS environment
(IBM/PC or compatible) to help customer to design the
character font on the screen and to generate the bit pattern
HEX decimal file automatically.
Contact your local Philips Sales Organization for details.

13 EMULATION MODE

The emulation mode configuration is shown in Fig.29.
In the emulation mode configuration the PCA84C640’s

CPU is disabled and only its derivative logic is active.
The device is controlled by the PCF84C00 bond-out chip.
The PCA84C640's two derivative ports act as additional
ports for the PCF84C00. The interaction between the two
devices is as follows:

1. During the first machine cycle the PCF84C00 fetches
an instruction from EPROM and then decodes that
instruction.

2. During the second machine cycle the PCF84C00
executes the decoded instruction. If the instruction is
related to the derivative ports then DXALE, DXRDN
and/or DXWRN become active and the PCA84C640
operates as a peripheral of the PCF84C00.

3. Depending on the type of instruction executed during
the second machine cycle the following data transfer
happens:

a) During TS1 data from the EPROM is available on

P0.0 to P0.7 which is then available on IB0.0 of the
PCF84C00.

b) During TS4 data from the PCA84C640 can be

transferred to the PCF84C00.

c) During TS6 data from the PCF84C00 can be

transferred to the PCA84C640.

19 SOLDERING

19.1 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
our

“IC Package Databook”

(order code 9398 652 90011).

19.2 Soldering by dipping or by wave

The maximum permissible temperature of the solder is

The total contact time of successive solder waves must not
exceed 5 seconds.

The device may be mounted up to the seating plane, but
the temperature of the plastic body must not exceed the
specified maximum storage temperature (T

stg max

). If the
printed-circuit board has been pre-heated, forced cooling
may be necessary immediately after soldering to keep the
temperature within the permissible limit.

19.3 Repairing soldered joints

Apply a low voltage soldering iron (less than 24 V) to the
lead(s) of the package, below the seating plane or not
more than 2 mm above it. If the temperature of the
soldering iron bit is less than 300 °C it may remain in
contact for up to 10 seconds. If the bit temperature is
between 300 and 400 °C, contact may be up to 5 seconds.

260 °C; solder at this temperature must not be in contact
with the joint for more than 5 seconds.
