M48T35AV

3.3 V, 256 Kbit (32 Kbit 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

■ Battery low flag (BOK)

■ Frequency test output for real-time clock

■ Automatic power-fail chip deselect and WRITE

protection

■ WRITE protect voltage

(VPFD = power-fail deselect voltage):

–M48T35AV: VCC = 3.0 to 3.6 V;

2.7 V

≤ VPFD ≤ 3.0 V

■ Self-contained battery and crystal in the

CAPHAT™ DIP package

■ SOIC package provides direct connection for a

SNAPHAT® housing containing the battery and

crystal

■ SNAPHAT® housing (battery and crystal) is

replaceable

■ Pin and function compatible with JEDEC

standard 32 Kbit x 8 SRAMs

■ RoHS compliant

– Lead-free second level interconnect
