M40SZ100Y

M40SZ100W

5V or 3V NVRAM supervisor for LPSRAM

Features

■ Convert low power SRAMs into NVRAMs

■ 5V or 3V operating voltage

■ Precision power monitoring and power

switching circuitry

■ Automatic write-protection when VCC is out-of-

tolerance

■ Choice of supply voltages and power-fail

deselect voltages:

– M40SZ100Y: VCC = 4.5 to 5.5V;

4.20V

≤ VPFD ≤ 4.50V

– M40SZ100W: VCC = 2.7 to 3.6V;

2.55V

≤ VPFD ≤ 2.70V

■ Reset output (RST) for power on reset

■ 1.25V reference (for PFI/PFO)

■ Less than 10ns chip enable access

propagation delay (at 5V)

■ Optional packaging includes a 28-lead SOIC

and SNAPHAT® top (to be ordered separately)

■ 28-lead SOIC package provides direct

connection for a SNAPHAT top which contains

the battery(a)

■ Battery low pin (BL)

■ RoHS compliant

–

Lead-free second level interconnect

a.
