Product Summary

The BQ2201SN is the CMOS SRAM Nonvolatile Controller Unit which 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 write-protect any standard CMOS SRAM.

Parametrics

BQ2201SN absolute maximum ratings: (1)DC voltage applied on VCC relative to VSS: -0.3 to 7.0 V; (2)DC voltage applied on any pin excluding VCC relative to VSS: -0.3 to 7.0 V; (3)Operating temperature: 0 to +70 ℃, -40 to +85 ℃; (4)Storage temperature: -55 to +125 ℃; (5)Temperature under bias: -40 to +85 ℃; (6)Soldering temperature: 260 ℃; (7)VOUT current: 200 mA.

Features

BQ2201SN features: (1)Power monitoring and switching for 3-volt battery-backup applications; (2)Write-protect control; (3)3-volt primary cell inputs; (4)Less than 10ns chip-enable propagation delay; (5)5% or 10% supply operation.
