M48T02

M48T12

5.0V, 16 Kbit (2Kb x 8) TIMEKEEPER® SRAM

Features

■ Integrated, ultra low power SRAM, real time

clock, and power-fail control circuit

■ BYTEWIDE™ RAM-like clock access

■ BCD coded year, month, day, date, hours,

minutes, and seconds

■ Typical clock accuracy of ±1 minute a month, at

25°C

■ Software controlled clock calibration for high

accuracy applications

■ Automatic power-fail chip deselect and WRITE

protection

■ WRITE protect voltages

(VPFD = Power-fail deselect voltage):

–M48T02: VCC = 4.75 to 5.5V

4.5V

≤ VPFD ≤ 4.75V

–M48T12: VCC = 4.5 to 5.5V

4.2V

≤ VPFD ≤ 4.5V

■ Self-contained battery and crystal in the

CAPHAT™ DIP package

■ Pin and function compatible with JEDEC

standard 2K x8 SRAMs

■ RoHS compliant

– Lead-free second level interconnect
