bq2201 - SRAM Nonvolatile Controller

Description

The CMOS bq2201 SRAM Nonvolatile Controller Unit provides all necessary functions for converting a standard CMOS SRAM into nonvolatile read/write memory.

A precision comparator monitors the 5V VCC input for an out-of-tolerance condition.

Features

® Power monitoring and switching for 3-volt battery-backup.

bq2201 SRAM Nonvolatile Controller Unit Features ® Power monitoring and switching for 3-volt battery-backup applications ® Write-protect control ® 3-volt primary cell inputs ® Less than 10ns chip-enable propagation delay ® 5% or 10% supply operation General Description The CMOS bq2201 SRAM Nonvolatile Controller Unit provides all necessary functions for converting a 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, a conditioned chip-enable output is forced inactive to writeprotect any standard CMOS SRAM. During a power failure, the external SRAM is switched from the VCC supply to one of two 3V backup supplies.
