PRODUCT DESCRIPTION

The SST30VR041/043 are ROM/RAM combo chips consisting of 4 Mbit Read Only Memory organized as 512 KBytes and a Static Random Access Memory organized as either 128 or 32 KBytes. Output Enable Input (OE#) is pin-shared with RAMCS# (RAM Enable Input) signal in order to maintain the standard 32-pin TSOP package.

The device is fabricated using SST’s advanced CMOS low power process technology.
