Part Number : BQ2204ASN-NTR
Function : X4 SRAM NONVOLATILE CONTROLLER IC
Package : DIP, SOIC 16 Pin
Maker : Texas Instruments
Pinouts : 
Description :
The CMOS BQ2204ASN-NTR, bq2204A SRAM Non-volatile 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 condi-tion. When out-of-tolerance is detected, the four conditioned chip-enable outputs are forced inactive to write-protect up to four banks of SRAM.
[ Features ]
1. Power monitoring and switching for 3-volt battery-backup applica tions
2. Write-protect control
3. 2-input decoder for control of up to 4 banks of SRAM
4. 3-volt primary cell inputs
5. Less than 10ns chip-enable propagation delay
6. 5% or 10% supply operation
