M48T08

M48T08Y, M48T18

5V, 64Kbit (8 Kb x 8) TIMEKEEPER® SRAM

Features

■ Integrated ultra low power sram, real time

clock, power-fail control circuit, and battery

■ 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

■ Automatic power-fail chip deselect and write

protection

■ Write protect

VPFD = Power-fail deselect voltage):

–M48T08: VCC = 4.75 to 5.5V

4.5V

≤ VPFD ≤ 4.75V

– M48T18/T08Y: VCC = 4.5 to 5.5V

4.2V

≤ VPFD ≤ 4.5V

■ Software controlled clock calibration for high

accuracy applications

■ Self-contained battery and crystal in the

CAPHAT™ dip package

■ Packaging includes a 28-lead SOIC and

SNAPHAT® top (to be ordered separately)

■ SOIC package provides direct connection for a

snaphat top which contains the battery and

crystal

■ Pin and function compatible with DS1643 and

JEDEC standard 8K x8 SRAMs

■ RoHS compliant

– Lead-free second level interconnect
