1.2
P8xCx66 family
– 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.

GENERAL DESCRIPTION
P8xCx66 family
The Philips 80C51 CPU is object code compatible with the
industry standard 80C51. All devices are manufactured in
an advanced CMOS technology.
The P8xCx66 family also function as arithmetic processors
having facilities for both binary and BCD arithmetic plus bit
handling capabilities. The instruction set consists of over
100 instructions: 49 one-byte, 46 two-byte and
16 three-byte. Multiply and divide instructions are
implemented by hardware with a cycle time of 4
µs
(f
CLK
= 12 MHz).
The term P8xCx66 is used throughout this data sheet to
refer to all family members; differences between devices
are highlighted in the text.
The P8xCx66 family consists of the following devices:
•
P83C266
•
P83C366
•
P83C566
•
P83C766
•
P87C766.
The P8xCx66 family are 80C51-based microcontrollers
designed for medium-high to high-end TV control
applications. The P8xCx66 devices incorporate many
unique features on-chip, giving them a competitive edge
over similar devices from other manufacturers.
