Product specification
Microcontrollers for PAL/SECAM TV
with OSD and VST
P8xCx66 family
1
FEATURES
1.1
P80C51 CPU core
80C51 8-bit CPU
64-kbyte Multiple Programming ROM (MTP ROM)
Two 16-bit timer/event counters
Crystal oscillator for system clock (up to 12 MHz)
12 source, 12 vector interrupt structure with two priority
levels
Enhanced architecture with:
– Non-page orientated instructions
– Direct addressing
– Four 8-byte RAM register banks
– Stack depth up to 128 bytes
– Multiply, divide, subtract and compare instructions.
1.2
P8xCx66 family
ROM/RAM: see Table 1
Pulse Width Modulated (PWM) outputs:
– One 14-bit PWM output for Voltage Synthesized
Tuning (VST)
– Eight 7-bit PWM outputs for analog controls.
3 Analog-to-Digital (ADC) inputs with 4-bit DAC and
comparator
LED driver port:
– All I/O port lines with 10 mA LED drive capability
(V
O
<1.0 V)
– Up to 5 LEDs can be driven at any one time.
Serial I/O:
– Multi-master I
2
C-bus interface
– Maximum I
2
C-bus frequency 400 kHz.
Watchdog timer
Improved EMC measures and slope controlled I/Os
OSD functions:
– Programmable VSYNC and HSYNC active levels
– Display RAM: 192
×
12 bits
– Display character fonts: 128 (126 customer fonts plus
2 reserved codes)
– 63 vertical starting positions controlled by software
– 110 horizontal starting positions controlled by
software
– Character size: 4 different character sizes on a
line-by-line basis
– Character matrix: 12
×
18 with no spacing between
characters
– Foreground colours: 8 on a character-by-character
basis
– Background/shadowing modes: two primary modes -
TV mode and Frame mode on a frame basis. Each
primary mode has four sub-modes on a line basis:
Sub-mode 1: Superimpose (no background)
Sub-mode 2: North-West shadowing
Sub-mode 3: Box background
Sub-mode 4: Border shadowing
– Background colours: 8 on a word-by-word basis,
available in all four sub-modes
– Display RAM starting address is programmable; fast
switching between banks of display (RAM)
characters is possible through software control
– HSYNC driven PLL for OSD clock (4 to 12 MHz)
– Character blinking ratio: 1 : 1
– Character blinking frequency: programmable using
f
VSYNC
divisors of 32 and 64, on a character basis
– Flexible display format using the Carriage Return
code and the Space codes
– Display RAM address post incremented each time
new data is written into RAM
– Vertical jitter cancelling circuit to avoid unstable
VSYNC leading edge mismatch with HSYNC signal
– OSD meshing.
Power-on reset
Packages: SDIL42 (PLCC68 for piggy-back only)
Operating voltage: 4.5 to 5.5 V
Operating temperature:
20 to +70
°
C
System clock frequency: 4 to 12 MHz
OSD clock frequency: 4 to 12 MHz.
