Note: 1. Soldering temperature not to exceed 260 for 10 seconds (total thermal budget not to exceed 150 for longer than 30 seconds).No preheat above 150, or direct exposure to IR reflow (or IR preheat) allowed, to avoid damaging the Lithium battery.


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 M48T128Y/V, quartz crystal, and a long life lithium button cell in a single package.
