M48Z02, M48Z12 5 V, 16 kbit (2 Kb x 8) ZEROPOWER SRAM Datasheet - production data 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 24 lithium button cell to form a highly integrated 1 battery-backed memory solution. PDIP 24.7 The M48Z02/12 button cell has sufficient capacity and storage life to maintain data functionality for Battery CAPHAT an accumulated time period of at least 10 years in the absence of power over commercial operating temperature range. Features The M48Z02/12 is a non-volatile pin and function equivalent to any JEDEC standard 2 K x 8 SRAM. Integrated, ultra low power SRAM and power- It also easily fits into many ROM, EPROM, and fail control circuit EEPROM sockets, providing the non-volatility of Unlimited WRITE cycles PROMs without any requirement for special WRITE timing or limitations on the number of READ cycle time equals WRITE cycle time WRITEs that can be performed.
