Features
Functional Description
The CY7C1021BN/CY7C10211BN is a high-performance
CMOS static RAM organized as 65,536 words by 16 bits. This
device has an automatic power-down feature that significantly
reduces power consumption when deselected.
Note:
1. For best-practice recommendations, please refer to the Cypress application note “System Design Guidelines” on http://www.cypress.com

Writing to the device is accomplished by taking Chip Enable
(CE) and Write Enable (WE) inputs LOW. If Byte Low Enable
(BLE) is LOW, then data from I/O pins (I/O

Reading from the device is accomplished by taking Chip
Enable (CE) and Output Enable (OE) LOW while forcing the
Write Enable (WE) HIGH. If Byte Low Enable (BLE) is LOW,
then data from the memory location specified by the address
pins will appear on I/O
LOW, then data from memory will appear on I/O

description of read and write modes.

high-impedance state when the device is deselected (CE
HIGH), the outputs are disabled (OE HIGH), the BHE and BLE
are disabled (BHE, BLE HIGH), or during a write operation (CE
LOW, and WE LOW).
The CY7C1021BN/CY7C10211BN is available in standard
44-pin TSOP Type II and 44-pin 400-mil-wide SOJ packages.
