DESCRIPTION
The Simtek STK12C68 is a fast static RAM with a
nonvolatile, electrically erasable PROM element
incorporated in each static memory cell. The SRAM
can be read and written an unlimited number of
times, while independent, nonvolatile data resides in
EEPROM
. Data transfers from the SRAM to the
EEPROM
(the STORE operation) can take place
automatically on power down. A 68
µF 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 EEPROM to the SRAM (the RECALL opera-
tion) take place automatically on restoration of
power. Initiation of STORE and RECALL cycles can
also be software controlled by entering specific read
sequences. A hardware STORE may be initiated with
the HSB pin.
