• Manufacturer Part Number: M48Z02-150PC1TR
• Description: 5V, 16 Kbit (2Kb x 8) ZEROPOWER SRAM
• Manufacturer: STMICROELECTRONICS [STMicroelectronics]

SUMMARY DESCRIPTION
The M48Z02/12 ZEROPOWER
non-volatile static RAM which is pin and functional
compatible with the DS1220.
A special 24-pin, 600mil DIP CAPHAT™ package
houses the M48Z02/12 silicon with a long life lithi-
um button cell to form a highly integrated battery
backed-up 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 2K 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.
