M40SZ100W - NVRAM supervisor
The M40SZ100W NVRAM controller is a selfcontained device which converts a standard lowpower SRAM into a non-volatile memory.
A precision voltage reference and comparator monitors the VCC input for an out-of-tolerance condition.
When an invalid VCC condition occurs, the conditioned chip enable output
