PCA8515

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

Description

The PCA8515 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 PCA8515 has also been designed for use in conventional mid-end TV with advanced graphic features.
