M48T37Y

M48T37V

5.0 or 3.3 V, 256 Kbit (32 Kbit x 8) TIMEKEEPER® SRAM

Features

■ Integrated ultra low power SRAM, real-time

clock, power-fail control circuit, and battery

■ Frequency test output for real-time clock

software calibration

■ Automatic power-fail chip deselect and WRITE

protection

■ Watchdog timer

■ WRITE protect voltage

(VPFD = Power-fail deselect voltage):

–M48T37Y: VCC = 4.5 to 5.5 V

4.2 V

≤ VPFD ≤ 4.5 V

–M48T37V: VCC = 3.0 to 3.6 V

2.7 V

≤ VPFD ≤ 3.0 V

■ Packaging includes a 44-lead SOIC and

SNAPHAT® top (to be ordered separately)

■ SOIC package provides direct connection for a

SNAPHAT® top which contains the battery and

crystal

■ Microprocessor power-on reset (valid even

during battery backup mode)

■ Programmable alarm output active in the

battery backup mode

■ Battery low flag

■ RoHS compliant

– Lead-free second level interconnect
