2 Features

2.1Memory Interface

16-bit DRAM interface:

EDO-DRAM up to 40MHz data rate (80M bytes per second).

FPM-DRAM up to 25MHz data rate (50M bytes per second).

Memory size options:

512K bytes using one 256K16 device.

2M bytes using one 1M16 device.

A configuration register can be programmed to enhance performance by tailoring the memory control output timing to the DRAM device.

2.2CPU Interface

Supports the following interfaces:

8/16-bit Hitachi SH-3 bus interface.

16-bit interface to 16/32-bit Motorola MC68K microprocessors/microcontrollers.

Philips MIPS PR31500 / PR31700.

NEC MIPS VR4102.

8/16-bit generic interface bus.

One-Stage write buffer for minimum wait-state CPU writes.

Registers are memory-mapped; M/R# pin selects between memory and register address space.

The complete 2M byte display buffer address space is directly and contiguously available through the 21-bit address bus.

2.3Display Support

4/8-bit monochrome or 4/8/16-bit color passive LCD interface for single-panel, single-drive displays.

8-bit monochrome or 8/16-bit color passive LCD interface for dual-panel, dual-drive displays.

Direct support for 9/12-bit TFT, 18/24-bit TFT are supported up to 64K color depth (16-bit data).

External RAMDAC support using the upper byte of the LCD data bus for the RAMDAC pixel data bus.

Simultaneous display of CRT and 4/8-bit passive panel or 9-bit TFT panel:

Normal mode for cases where LCD and CRT image sizes are identical.

Line-Doubling mode for simultaneous display of 240-line images on 240-line LCD and 480- line CRT.

Even-Scan and interlace modes for simultaneous display of 480-line images on 240-line LCD and 480-line CRT.
