bq2204A - X4 SRAM Nonvolatile Controller
The CMOS bq2204A SRAM Nonvolatile Controller Unit provides all necessary functions for converting up to four 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 four
