M48T128Y

M48T128V

5.0 or 3.3 V, 1 Mbit (128 Kb 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):

–M48T128Y: VCC = 4.5 to 5.5 V

4.1 V

≤ VPFD ≤ 4.5 V

–M48T128V: VCC = 3.0 to 3.6 V

2.7 V

≤ VPFD ≤ 3.0 V

(contact the ST sales office for availability)

■ 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

■ Self-contained battery and crystal in the DIP

package

■ Pin and function compatible with JEDEC

standard 128 K x 8 SRAMs

■ RoHS compliant

– Lead-free second level interconnect
