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
