M40SZ100W - NVRAM supervisor

Datasheet Summary

Description

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.

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  VPFD  2.70 V.
  • Reset output (RST) for power on reset.
  • 1.25 V reference (for PFI/PFO).
  • Less than 15 ns chip enable access propagation delay.
  • Battery low pin (BL).
  • RoHS compliant.
