On power-up, once Vcc exceeds the Vcc sense voltage of
3.3V, a RECALL cycle is automatically initiated. The voltage
on the Vcc pin must not drop below 3.3V once it has risen
above it in order for the RECALL to operate properly. Due to
this automatic RECALL, SRAM operation cannot commence
until tRECALL after Vcc exceeds 3.3V.
PACKAGE DETAILS
Dimensions are shown thus: mm (in). For further package
information please contact your local Customer Service
Centre.
The automatic RECALL feature can be adversely affected
by factors such as supply rise time, temperature and elapsed
time since the last STORE cycle. For this reason it is
recommended that the user initiate a RECALL cycle after
power-up for critical applications.
