M48Z18-100PC1TR Datasheet PDF - ST Microelectronics

●Description

●The M48Z08/18 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 M48Z08/18 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.

●Features

●■ Integrated, ultra low power SRAM and power fail 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
