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
M40SZ100W Features
* Convert low power SRAMs into NVRAMs
* 3 V operating voltage
* Precision power monitoring and power switching circuitry
* Automatic write-protection when VCC is out-of- tolerance
* Choice of supply voltage and power-fail deselect voltage:
* VCC = 2.7 to 3.6 V; 2.55 V V
