Description
The S71PLxxxHx0 contains a 67,108,864-bit, pseudo static random access mem-
ory (PSRAM) organized as 4,194,304 words by 16 bits. It provides high density,
high speed, and low power. The device operates on a single power supply. The
device also features SRAM-like W/R timing whereby the device is controlled by
CE1#, OE#, and WE# on asynchronous. The device has the page access opera-
tion. Page size is 8 words. The device also supports deep power-down mode,
realizing low-power standby.
