5.0 or 3.3V, 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
■ Year 2000 compliant
■ Automatic power-fail chip deselect and WRITE
protection
■ Watchdog timer
■ WRITE protect voltage
(VPFD = Power-Fail Deselect Voltage):
–M48T37Y:VCC = 4.5 to 5.5V
4.2V
≤ VPFD ≤ 4.5V
–M48T37V: VCC = 3.0 to 3.6V
2.7V

■ 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 back-up mode)
■ Programmable alarm output active in the
battery back-up mode
■ Battery low flag
■ RoHS compliant
– Lead-free second level interconnect
