M48T58Y

5.0 V, 64 Kbit (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

■ Frequency test output for real-time clock

■ Automatic power-fail chip deselect and write

protection

■ Write protect voltages

(VPFD = power-fail deselect voltage):

–M48T58: VCC = 4.75 to 5.5 V

4.5 V

≤ VPFD ≤ 4.75 V

–M48T58Y: VCC = 4.5 to 5.5 V

4.2 V

≤ VPFD ≤ 4.5 V

■ 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 housing containing the battery and

crystal

■ Pin and function compatible with JEDEC

standard 8 Kb x 8 SRAMs

■ RoHS compliant

– Lead-free second level interconnect
