1 Mbit Versatile SPI / 8-Bit Parallel Bus SRAM with Video Display Controller

Introduction

The VLSI Solution VS23S010 is an easy to use, large capacity one megabit static RAM device. The memory can be accessed via a standard SPI compatible serial bus (1, 2 and 4-bit modes), or via an 8080-type 8-bit parallel bus similar to nand flash devices.

One of the main applications for the VS23S010 is microcontroller RAM extension. Internet streaming applications, which are becoming increasingly popular, will benefit from the large buffer memory provided by VS23S010.

In addition to being used purely as a memory storage device the VS23S010 also contains a Video Display Controller that can output NTSC or PAL composite video from the memory array data to implement a video frame buffer.

VS23S010 is available in two variants: the fully featured LQFP-48 variant VS23S010D-L, and the memory-only featured Narrow SOIC8 VS23S010D-S which omits video and the 8-bit parallel bus.
