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 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) sepa-
rate 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.
