CY7C1021BN

1-Mbit (64 K × 16) Static RAM

Features

■

Functional Description

The CY7C1021BN 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.

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 the input/output (I/O) pins (I/O

through

I/O

), is written into the location specified on the address pins (A

through A

). If Byte High Enable (BHE) is LOW, then data from

I/O pins (I/O

through I/O

) is written into the location specified

on the address pins (A

through A

Reading from the device is accomplished by taking CE and

Output Enable (OE) LOW while forcing WE HIGH. If BLE is LOW,

then data from the memory location specified by the address pins

appears on I/O

to I/O

. If BHE is LOW, then data from memory

appears on I/O

to I/O

. See the

Truth Table on page 11

for a

complete description of read and write modes.

The I/O pins (I/O

through I/O

) are placed in a 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, WE LOW).

The CY7C1021BN is available in standard 44-pin TSOP type II

and 44-pin 400-mil-wide SOJ packages. Use part number

CY7C1021BN when ordering 15 ns t
