The CMOS bq2502 Integrated Backup Unit provides all the necessary functions for converting one or two banks of standard CMOS SRAM into nonvolatile read/write memory.
A precision comparator monitors the 5V VCC input for an out-of-tolerance condition.
When out of tolerance is detected, the two conditioned chip-enable outputs are forced inactive to write-protect both banks of SRAM.
