JEDEC STANDARD 2Kb x8 SRAMs

DESCRIPTION

The M48T02/12 TIMEKEEPER® RAM is a 2Kb x8

non-volatile static RAM and real time clock which

is pin and functional compatible with the DS1642.

A special 24 pin 600mil DIP CAPHAT

™ package

houses the M48T02/12 silicon with a quartz crystal

and a long life lithium button cell to form a highly

integratedbatterybacked-upmemory and real time

clock solution.
