3 / 64 page  1995 Mar 30 3 Philips Semiconductors Preliminary specification Stand-alone OSD 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. 3 ORDERING INFORMATION TYPE NUMBER PACKAGE NAME DESCRIPTION VERSION PCA8516P SDIP24 plastic shrink dual in-line package; 24 leads (400 mil) SOT234-1 PCA8516T SO24 plastic small outline package; 24 leads; body width 7.5 mm SOT137-1 |
