PRODUCT DESCRIPTION

The SST30VR021/022/023 are ROM/RAM combo chips

consisting of 2 Mbit Read Only Memory organized as 256

KBytes and Static Random Access Memory organized as

128, 256, and 32 KBytes.

The SST30VR021/022/023 has an output enable input for

precise control of the data outputs. It also has two (2) sepa-

rate chip enable inputs for selection of either RAM or ROM

and for minimizing current drain during power-down mode.

The device is fabricated using SST’s advanced CMOS low

power process technology.

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.
