In addition to transients that are caused by normal SRAM operation, power cycling can
generate negative voltage spikes on V
one volt. These negative spikes can cause data corruption in the SRAM while in battery
backup mode. To protect from these voltage spikes, STMicroelectronics recommends
connecting a Schottky diode from V
Schottky diode 1N5817 is recommended for through hole and MBRS120T3 is
recommended for surface mount.
