Features

Functional Description

■ Temperature ranges

❐ Industrial: –40 °C to 85 °C

❐ Automotive-A: –40 °C to 85 °C

The CY7C1021DV33 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.

■ Pin-and function-compatible with CY7C1021CV33

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/O₀through I/O₇), is written into

the location specified on the address pins (A₀through A₁₅). If

Byte High Enable (BHE) is LOW, then data from I/O pins (I/O₈

through I/O₁₅) is written into the location specified on the address

pins (A₀through A₁₅).

■ High speed

❐ t_AA= 10 ns

■ Low active power

❐ I_CC= 60 mA @ 10 ns

■ Low CMOS standby power

❐ I_SB2= 3 mA

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/O₀to I/O₇. If Byte High Enable (BHE) is LOW, then

data from memory will appear on I/O₈to I/O₁₅. See the truth table

at the end of this data sheet for a complete description of Read

and Write modes.

■ 2.0 V data retention

■ Automatic power-down when deselected

■ CMOS for optimum speed/power

■ Independent control of upper and lower bits

■ Available in Pb-free 44-pin 400-Mil wide molded SOJ, 44-pin

TSOP II and 48-ball VFBGA packages

The input/output pins (I/O₀through I/O₁₅) 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, and WE LOW).

The CY7C1021DV33 is available in Pb-free 44-pin 400-Mil wide

Molded SOJ, 44-pin TSOP II and 48-ball VFBGA packages.
