Description
The M48Z128/Y/V ZEROPOWER
as131,072 words by 8 bits. The device combines an internal lithium battery, a CMOS SRAM
and a control circuit in a plastic, 32-pin DIP module to provide a highly integrated battery-
backed memory solution.
The M48Z128/Y/V is a non-volatile pin and function equivalent to any JEDEC standard
128 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 32-pin, 600 mil DIP
module houses the M48Z128/Y/V silicon with a long-life lithium button cell in a single
package.
