DESCRIPTION
The LH5P8128 is a 1M bit Pseudo-Static RAM
organized as 131,072
×
8 bits. It is fabricated using
silicon-gate CMOS process technology.
A PSRAM uses on-chip refresh circuitry with a DRAM
memory cell for pseudo static operation which elimi-
nates external clock inputs, while having the same
pinout as industry standard SRAMs. Moreover, due to
the functional similarities between PSRAMs and
SRAMs, existing 128K
×
8 SRAM sockets can be filled
with the LH5P8128 with little or no changes. The
advantage is the cost savings realized with the lower
cost PSRAM.
The LH5P8128 PSRAM has the ability to fill the gap
between DRAM and SRAM by offering low cost, low
power standby and a simple interface.
