M40Z300

M40Z300W

5V or 3V 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 V 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

SO16 (MQ)

deselect voltages:

– M40Z300:

= 4.5V to 5.5V

THS = V : 4.5V ≤ V

≤ 4.75V

≤ 4.5V

PFD

THS = V

: 4.2V ≤ V

OUT

PFD

– M40Z300W:

= 3.0V to 3.6V

SNAPHAT (SH)

crystal/battery

THS = V : 2.8V ≤ V

≤ 3.0V

≤ 2.7V

PFD

= 2.7V to 3.3V

THS = V

: 2.5 ≤ V

OUT

PFD

■ Reset output (RST) for power on reset

■ Battery low pin (BL)

■ Less than 12ns chip enable access

propagation delay (for 5.0V 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

SOH28 (MH)

SNAPHAT top which contains the battery

■ RoHS compliant

– Lead-free second level interconnect
