Description

function compatible with the DS1225.

The monolithic chip provides a highly integrated battery-backed memory solution.

The M48Z08/18 is a non-volatile pin and function equivalent to any JEDEC standard 8 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.

The 28-pin, 600 mil DIP CAPHAT™ houses the M48Z08/18 silicon with a long-life lithium

button cell in a single package.
