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.

Key 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 - Lead-free second level interconnect Datasheet - production data
