5.0 Or 3.3V, 1 Mbit (128 Kbit X 8) TIMEKEEPER® SRAM

The M48T129V M48T129Y TIMEKEEPER RAM is 128 Kb x 8 non-volatile static RAM and real-tim Clock with programmable alarms and a watchdo Timer The special DIP package provides a fully in tegrated battery back-up memory and real-tim Clock solution. The M48T129V M48T129Y directly replace industry standard 128 Kb x 8 SRAM It also pro vides the non-volatility of Flash without any re quirement for special WRITE Timing or limitation on the number of WRITEs that CAN be performed. For surface-mount environments ST provides a equivalent SMT solution consisting of a 44-pin 330mil SOIC TIMEKEEPER SUPERVISOR M48T201V M48T201Y) and a 32-pin, (TSOP, 8 x 20mm 1Mb LPSRAM.
