Functional Description
The Cypress CY22E016L is a fast static RAM
with a nonvol-
atile element incorporated in each static memory cell. The
SRAM
can be read and written an infinite number of times,
while independent, nonvolatile data resides in Nonvolatile
Elements. Data transfers from the SRAM
to the Nonvolatile
Elements (the STORE
operation) can take place automatically
on power down. A 68-
μ
F or larger capacitor tied from V
CAP
to
ground guarantees the STORE
operation, regardless of
power-down slew rate or loss of power from “hot swapping”.
Transfers from the Nonvolatile Elements to the SRAM
(the
RECALL
operation) take place automatically on restoration of
power. A hardware STORE
may be initiated with the HSB pin.
