M48T128V* General Description
The M48T128Y/V TIMEKEEPER® RAM is a 128Kb x 8 non-volatile static RAM and real time clock. The special DIP package provides a fully integrated battery back-up memory and real time clock solution. The M48T128Y/V directly replaces industry standard 128Kb 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.The 32-pin, 600mil DIP Hybrid houses a controller chip, SRAM, quartz crystal, and a long life lithium button cell in a single package.
