DESCRIPTION
The Simtek STK12C68-IM is a fast static
RAM
(25, 35
and 45ns), with a nonvolatile
EEPROM
element incor-
porated 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
) take place automatically upon power down
using charge stored in an external 100
μ
F capacitor.
Transfers from the
EEPROM
to the
SRAM
(the
RECALL
operation) take place automatically on power up. Soft-
ware sequences may also be used to initiate both
STORE
and
RECALL
operations. A
STORE
can also be
initiated via a single pin.
The STK12C68-IM is available in the following
packages: a 28-pin 300 mil ceramic DIP and a 28-pad
LCC. MIL-STD-883 and Standard Military Drawing
(SMD 5962-94599) devices are also available.
