Description
The VLSI Solution VS23S010C-S is an easy-
to-use and versatile serial SRAM device. The
memory is accessed via an SPI compatible
serial bus.
Applications
• Microcontroller RAM extension
• VoIP and internet data stream buffer
• Audio data buffer

In SPI mode SRAM and control registers can
be accessed. Dual-I/O and Quad-I/O modes
are used only for SRAM read and write.
Following are connection examples for differ-
ent operating modes. Some I/Os of VS23S010C-
S are unconnected, because they have inter-
nal pull-up or pull-down resistors. Note also,
