BQ2201PN TI SRAM Nonvolatile Controller | 8-PDIP | 3V-3.6V, 5V

Product Overview

The BQ2201PN from Texas Instruments is a nonvolatile SRAM controller designed to provide battery backup and memory protection for SRAM modules. It integrates power-fail detection, battery switchover, and write protection in a compact 8-pin PDIP package. The device ensures data retention during power loss by automatically switching to a backup battery and asserting chip-enable (CE) inhibit to prevent spurious writes. Ideal for industrial and telecom applications requiring reliable data storage.
