1 Description
The M48Z02/12 ZEROPOWER
®
RAM is a 2 K x 8 non-volatile static RAM which is pin and
function compatible with the DS1220.
A special 24-pin, 600 mil DIP CAPHAT™ package houses the M48Z02/12 silicon with a
long-life lithium button cell to form a highly integrated battery-backed memory solution.
The M48Z02/12 button cell has sufficient capacity and storage life to maintain data
functionality for an accumulated time period of at least 10 years in the absence of power
over commercial operating temperature range.
The M48Z02/12 is a non-volatile pin and function equivalent to any JEDEC standard 2 K x 8
SRAM. It also easily fits into many ROM, EPROM, and EEPROM sockets, providing the
non-volatility of PROMs without any requirement for special WRITE timing or limitations on
the number of WRITEs that can be performed.
