Product overview

Description

The M40SZ100W NVRAM controller is a self-contained device which converts a standard low-power SRAM into a non-volatile memory. A precision voltage reference and comparator monitors the VCCinput for an out-of-tolerance condition. When an invalid VCCcondition occurs, the conditioned chip enable output (ECON)is forced inactive to write protect the stored data in the SRAM. During a power failure, the SRAM is switched from the VCCpin to the external battery to provide the energy required for data retention. On a subsequent power-up, the SRAM remains write-protected until a valid power condition returns.
  • All features

    • Convert low power SRAMs into NVRAMs
    • 3 V operating voltage
    • Precision power monitoring and power switching circuitry
    • Automatic write-protection when VCCis 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
