Preliminary specification
PCA8516
1 FEATURES
• Display RAM: 256 × 13 bits
• Display character fonts: 253 (fixed in ROM, mask
programmable)
• Starting position of the first character displayed:
64 vertical and 64 horizontal starting positions can be
selected by software
• Character size: 4 different character sizes on a
line-by-line basis (1 dot = 1H/1V; 2H/2V; 3H/3V and
4H/4V)
• Character matrix: 12 × 18 with no spacing between
characters and no rounding function
• Foreground colours: 16 combinations of Red, Green,
Blue and Intensity on character-by-character basis
• Background/shadowing modes: 4 modes available, No
background, Box shadowing, North-West shadowing
and Frame shadowing (raster blanking) on frame basis
• Background colours: 16 combinations of Red, Green,
Blue and Intensity on word-by-word basis. Available
when background mode is in either the Box shadowing,
North-West shadowing or Frame shadowing mode
• OSD oscillator: on-chip Phase-Locked Loop (PLL)
• Character blinking ratio: 1 : 1, 1 : 3 and 3 : 1
(programmable frequency of 1⁄16, 1⁄32, 1⁄64 or 1⁄128 of
fVSYNC) on character basis
• Display format: flexible display format by using the
Carriage Return Code, maximum number of characters
per line is also flexible and depends upon the OSD clock
frequency
• Spacing between lines: 4 choices comprising 0, 4, 8 and
12 horizontal scan lines
• Display character RAM address auto-post-increment
when writing data
• Fast I2C-bus serial interface (400 kbaud) or High-speed
3-wire serial interface (1 Mbaud) for data/command
transfer
• ACM (Active Character Monitor) specifically for use in
camcorder applications on word basis; can also be used
as a 5th colour control with R, G, B and I signals
• Programmable active input polarity of HSYNC and
VSYNC
• Programmable output polarity of R, G, B, I and FB
• Supply voltage: 5 V ±10%
• Operating temperature: −20 to +70 °C
• Package: SDIP24 or SO24.
2 GENERAL DESCRIPTION
The PCA8516 is a member of the PCA85XX CMOS family
and is an on-screen character display generator controlled
by a microcontroller via the on-chip fast I2C-bus interface
or the on-chip High-speed 3-wire serial interface. It is
suitable for use in high-end TV or camrecorder
applications and has also been designed for use in
conventional mid-end TV with advanced graphic features.
