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 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
    – Lead-free second level interconnect
