DESCRIPTION
The Simtek STK14C88 is a fast static
RAM
with a
nonvolatile element incorporated in each static
memory cell. The
SRAM
can be read and written an
unlimited number of times, while independent, non-
volatile data resides in the nonvolatile elements.
Data transfers from the
SRAM
to the nonvolatile ele-
ments (the
STORE
operation) can take place auto-
matically on power down. A 68µF 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. 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.

Why is it that the MCU resets when the power supply is unstable but the timer continues to work?
I made a timer alarm. After the timer starts, the microcontroller automatically resets after a period of time due to unstable power supply. But strangely, the timer is still working and still flashes ...
