DESCRIPTION
The LH5P8129 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 considering the pinout
compatibility with industry standard SRAMs. The
advantage is the cost savings realized with the lower
cost PSRAM.
The LH5P8129 PSRAM has a built-in oscillator, which
makes it easy to refresh memories without external
clocks.
