STMicroelectronics Zeropower SRAM 64K DIP28
STMicroelectronics Zeropower SRAM 64K DIP28. Non-volatile 8K x 8 RAM with 100ns access time & automatic power-fail protection.
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.
