DESCRIPTION
The STK16C88 is a fast
SRAM
with a nonvolatile
EEPROM
element incorporated in each static mem-
ory cell. The
SRAM
can be read and written an
unlimited number of times, while independent non-
volatile data resides in
EEPROM
. Data transfers from
the
SRAM
to the
EEPROM
(the
STORE
operation) can
take place automatically on power down. An internal
capacitor guarantees the
STORE
operation regard-
less of power-down slew rate. Transfers from the
EEPROM
to the
SRAM
(the
RECALL
operation) take
place automatically on restoration of power. Initia-
tion of
STORE
and
RECALL
cycles can also be con-
trolled by entering control sequences on the
SRAM
inputs. The STK16C88 is pin-compatible with 32k x
8
SRAM
s and battery-backed
SRAM
s, allowing direct
substitution while enhancing performance. The
STK14C88, which uses an external capacitor, and
the STK15C88, which uses charge stored in system
capacitance, are alternatives for systems needing
AutoStorePlus
operation.
