bq2205LY General Description

The CMOS bq2205 SRAM non-volatile controller with reset provides all the necessary functions for converting one or two banks of standard CMOS SRAM into non-volatile read/write memory. A precision comparator monitors the 3.3-V VCC input for an out-of-tolerance condition. When out-of-tolerance is dete.
