The device is fabricated using SST’s advanced CMOS low power process technology. The SST30VR021/022/023 has an output enable input for precise control of the data outputs. It also has two (2) separate chip enable inputs for selection of either RAM or ROM and for minimizing current drain during power-down mode. The SST30VR021/022/023 is particularly well suited for use in low voltage (2.7-3.3V) supplies such as pagers, organizers and other handheld applications.
