M48T129Y
M48T129V
5.0 or 3.3 V, 1 Mbit (128 Kbit x 8) TIMEKEEPER® SRAM
Not recommended for new design
Features
■ Integrated, ultra low power SRAM, real-time
clock, power-fail control circuit, battery, and
crystal
)■ BCD coded century, year, month, day, date,
t(shours, minutes, and seconds
c■ Battery low warning flag
du■ Automatic power-fail chip deselect and WRITE
roprotection
P■ Two WRITE protect voltages:
te(VPFD = power-fail deselect voltage)
le– M48T129Y: VCC = 4.5 to 5.5 V;
4.2 V ≤ VPFD ≤ 4.5 V
so– M48T129V: VCC = 3.0 to 3.6 V;
b2.7 V ≤ VPFD ≤ 3.0 V
O■ Conventional SRAM operation; unlimited
-WRITE cycles
t(s)■ Software controlled clock calibration for high
accuracy applications
uc■ 10 years of data retention and clock operation
din the absence of power
ro■ Self-contained battery and crystal in DIP
Ppackage
te■ Microprocessor power-on reset
le(valid even during battery backup mode)
so■ Programmable alarm output active in battery
Obbackup mode
32
1
PMDIP32 module
■ RoHS compliant
– Lead-free second level interconnect
