M48Z18 - 64 Kbit (8 Kb x 8) ZEROPOWER SRAM
The M48Z08/18 ZEROPOWER® RAM is a 8 kbit 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 kbit x 8 SRA
M48Z18 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):
