The DS1312 from Analog Devices / Maxim Integrated is a CMOS nonvolatile controller that provides essential functions for converting CMOS SRAM into nonvolatile memory. It features automatic switching to a battery backup supply during VCC power failures and write-protects the SRAM when VCC is out of tolerance. The device also monitors the voltage of a lithium cell, providing an advanced warning of impending battery failure via its active-low Battery Warning output.
This controller supports an operating voltage range of 4.75V to 5.5V and operates reliably within an industrial temperature range of -40°C to +85°C. It is available in a space-saving 8-pin DIP package (0.300" width) and offers optional 5% or 10% power-fail detection. The DS1312 is suitable for applications requiring robust memory backup and data integrity.
Key features include unconditional write-protection of SRAM during power failures, automatic battery backup switching, and low-battery condition signaling. The device's precise voltage detection circuitry ensures minimal battery consumption, making it an efficient solution for critical data retention needs.
