Description

The VLSI Solution VS23S010D-L is an easyto-

use and versatile serial SRAM device. The

memory is accessed via an SPI compatible

serial bus. The device also contains Video

Display Controller, which can be configured

to continuously output analog composite video

from the memory array data to implement a

video frame buffer.

Alternatively, a 8-bit parallel interface can be

used to access the SRAM instead of the SPI.

To sum up, there are four separate operating

modes in VS23S010D-L:

 SPI Single, Dual, or Quad operation and

4 General Purpose I/O pins

 SPI Single, Dual, or Quad operation and

simultaneous Video Display Controller

 8-bit Parallel Interface operation
