Features
Functional Description
The CY7C1020V is a high-performance CMOS static RAM or-
ganized as 32,768 words by 16 bits. This device has an auto-
matic power-down feature that significantly reduces power
consumption when deselected.
Writing to the device is accomplished by taking chip enable
(CE) and write enable (WE) inputs LOW. If byte low enable

Reading from the device is accomplished by taking chip en-
able (CE) and output enable (OE) LOW while forcing the write
enable (WE) HIGH. If byte low enable (BLE) is LOW, then data

HIGH), the outputs are disabled (OE HIGH), the BHE and BLE
are disabled (BHE, BLE HIGH), or during a write operation (CE

The CY7C1020V is available in standard 44-pin TSOP type II
and 400-mil-wide SOJ packages.
