STMICROELECTRONICS M48Z08-100PC1 NVRAM, SRAM, 64 Kbit, 8K x 8bit, Parallel, 100 ns, DIP Vello EPF-XTL 4 mm) Outer Shield MaterialThe M48Z08 100PC1 is a ZEROPOWER RAM 8K x 8 Non volatile Static RAM which is pin and function compatible with the DS1225. The monolithic chip provides a highly integrated battery backed memory solution. 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. Integrated, ultralow power SRAM and power
