CY7C1021DV33

1-Mbit (64K x 16) Static RAM

Features

Functional Description^[1]

• Temperature Ranges

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.

— Industrial: –40°C to 85°C

— Automotive-A: –40°C to 85°C

— Automotive-E: –40°C to 125°C

• Pin-and function-compatible with CY7C1021CV33

• High speed

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 (A₀

through A₁₅). If Byte High Enable (BHE) is LOW, then data

from I/O pins (I/O₈through I/O₁₅) is written into the location

specified on the address pins (A₀through A₁₅).

— t_AA= 10 ns

• Low active power

— I_CC= 60 mA @ 10 ns

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.

• Low CMOS standby power

— I_SB2= 3 mA

• 2.0V 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.
