DESCRIPTION
The M48T513Y/V TIMEKEEPER RAM is a 512Kb
x 8 non-volatile static RAM and real time clock,
with programmable alarms and a watchdog timer.
The special DIP package provides a fully integrat-
ed battery back-up memory and real time clock so-
lution. The M48T513Y/V directly replaces industry
standard 512Kb 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 36 pin 600 mil DIP Hybrid houses a controller
chip, SRAM, quartz crystal, and a long life lithium
button cell in a single package.
