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
 8-bit Parallel Interface operation and simultaneous
Video Display Controller
