The VLSI Solution VS23S010 is an easy to use static RAM device. With one megabit capacity it is the largest capacity SPI RAM on the market. 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.
The main applications of the device are microcontroller RAM extension and audio buffer for internet and personal streaming.
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 pattern generation logic. When VS23S010’s RAM is accessed through the SPI bus, it can simultaneously output a repeating memory data pattern through four of its parallel bus pins. www.vlsi.fi/samples/vs23s010
