STMicroelectronics Zeropower SRAM 64K DIP28

The STMicroelectronics Zeropower SRAM 64K is an 8K x 8 Non-volatile Static RAM that is pin and function compatible with JEDEC standard 8K x 8 SRAMs. The monolithic chip provides a highly integrated battery-backed memory solution, making it an ideal choice for systems requiring reliable data retention. It easily fits into many ROM, EPROM and EEPROM sockets, delivering the non-volatility of PROMs without requiring special write timing or placing limitations on the number of write cycles that can be performed.

Key Features

• Integrated, ultralow power SRAM and power-fail control circuit
• READ cycle time equals WRITE cycle time
• Automatic power-fail chip deselect and WRITE protection
• Pin and function compatible with JEDEC standard 8K x 8 SRAMs

Important Handling Warning

Negative undershoots below -0.3V are strictly not allowed on any pin while the device is in battery backup mode. Proper handling ensures the integrity and longevity of the memory chip.
