GENERAL DESCRIPTION
The SA56600-42 is designed to protect SRAM data in computer systems during periods of sagging power supply voltages and power outages.
When the power supply voltage drops to typically 4.
2 V, the CS output goes to a logic LOW state pulling CE to a LOW state, disabling the SRAM device.
In addition, a reset logic LOW is asserted for system use.
If the supply voltage drops further, to 3.
3...
