M48T512Y
M48T512V
5.0 or 3.3 V, 4 Mbit (512 Kbit x 8) TIMEKEEPER SRAM
Features
Integrated ultra low power SRAM, real-time
clock, power-fail control circuit, battery, and
crystal
BCD coded year, month, day, date, hours,
minutes, and seconds
Automatic power-fail chip deselect and WRITE
protection
WRITE protect voltages:
(VPFD = Power-fail deselect voltage)

4.2 V
≤ VPFD ≤ 4.5 V
–M48T512V: VCC = 3.0 to 3.6 V
2.7 V
≤ VPFD ≤ 3.0 V

Conventional SRAM operation; unlimited
WRITE cycles
Software controlled clock calibration for high
accuracy applications
10 years of data retention and clock operation
in the absence of power
Pin and function compatible with industry
standard 512 K x 8 SRAMS
Self-contained battery and crystal in DIP
package
