M48T35
M48T35Y
5 V, 256 Kbit (32 Kb x 8) TIMEKEEPER SRAM
Features
■ Integrated, ultralow 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):
–M48T35: VCC = 4.75 to 5.5 V
– 4.5 V
≤ VPFD ≤ 4.75 V
–M48T35Y: VCC = 4.5 to 5.5 V
–4.2V
≤ VPFD ≤ 4.5 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 Kb x 8 SRAMs
■ RoHS compliant
– Lead-free second level interconnect
