DESCRIPTION
The STK16C88-3 is a fast
element incorporated in each static memory cell.
The
number of times, while independent nonvolatile data
resides in Nonvolatile Elements. Data transfers from
the
operation) can take place automatically on power
down. An internal capacitor guarantees the
operation regardless of power-down slew rate.
Transfers from the Nonvolatile Elements to the
SRAM
cally on restoration of power. Initiation of
RECALL
control sequences on the
STK16C88-3 is pin-compatible with 32k x 8
and battery-backed
tion while providing superior performance. The
STK14C88-3, which uses an external capacitor, is
also available.
