Description

1 piece M48T129Y-70PM1
TIMEKEEPER® SRAM
1 Mbit (128 Kbit x 8) | 70ns | Vcc 4.5 to 5.5 V | PMDIP32 package
Manufacturer: STMicroelectronics
Package: PMDIP32
Product Family: TIMEKEEPER® SRAM
INTEGRATED, ULTRA LOW POWER SRAM, REAL TIME CLOCK, POWER-FAIL CONTROL CIRCUIT, BATTERY, AND CRYSTAL
BATTERY LOW WARNING FLAG
The M48T129Y/V TIMEKEEPER® RAM is a 128 Kb x 8 non-volatile static RAM and real-time clock with programmable alarms and a watchdog timer. The special DIP package provides a fully integrated battery back-up memory and real-time clock solution. The M48T129Y/V directly replaces industry standard 128 Kb x 8 SRAM. It also provides the non-volatility of Flash without any requirement for special WRITE timing or limitations on the number of WRITEs that can be performed.
For surface-mount environments ST provides an equivalent SMT solution consisting of a 44-pin, 330mil SOIC TIMEKEEPER SUPERVISOR (M48T201V/Y) and a 32-pin, (TSOP, 8 x 20mm) 1Mb LPSRAM.
