M40Z300

M40Z300W

5 V or 3 V NVRAM supervisor for up to 8 LPSRAMs

Features

■ Converts low power SRAM into NVRAMs

■ Precision power monitoring and power

switching circuitry

■ Automatic WRITE-protection when VCC is out-

of-tolerance

■ Two-input decoder allows control for up to

8 SRAMs (with 2 devices active in parallel)

■ Choice of supply voltages and power-fail

deselect voltages:

–M40Z300:

VCC = 4.5 V to 5.5 V

THS = VSS: 4.5 V ≤ VPFD ≤ 4.75 V

THS = VOUT: 4.2 V ≤ VPFD ≤ 4.5 V

–M40Z300W:

VCC = 3.0 V to 3.6 V

THS = VSS: 2.8 V ≤ VPFD ≤ 3.0 V

VCC = 2.7 V to 3.3 V

THS = VOUT: 2.5 V ≤ VPFD ≤ 2.7 V

■ Reset output (RST) for power on reset

■ Battery low pin (BL)

■ Less than 12 ns chip enable access

propagation delay (for 5.0 V device)

■ Packaging includes a 28-lead SOIC and

SNAPHAT® top (to be ordered separately), or

A 16-lead SOIC

■ SOIC package provides direct connection for a

SNAPHAT top which contains the battery

■ RoHS compliant

– Lead-free second level interconnect
