Description
The M48Z08-100PC1 ZEROPOWER® RAM is an 8 K 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. The M48Z08-100PC1 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 M48Z08-100PC1 silicon with a long-life lithium button cell in a single package.
Features
■ Integrated, ultra low power SRAM and powerfail control circuit
■ Unlimited WRITE cycles
■ READ cycle time equals WRITE cycle time
■ Automatic power-fail chip deselect and WRITE protection
■ WRITE protect voltages(VPFD = power-fail deselect voltage):
– M48Z08: VCC = 4.75 to 5.5 V;4.5 V ≤ VPFD ≤ 4.75 V
– M48Z18: VCC = 4.5 to 5.5 V;4.2 V ≤ VPFD ≤ 4.5 V
■ Self-contained battery in the CAPHAT™ DIP package
■ Pin and function compatible with JEDEC standard 8 K x 8 SRAMs
■ RoHS compliant
– Lead-free second level interconnect
