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
