CY7C1021CV33

1-Mbit (64K x 16) Static RAM

Features

Functional Description^[1]

• Temperature Ranges

The CY7C1021CV33 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.

— Commercial: 0°C to 70°C

— 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 CY7C1021BV33

• 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/O₁through I/O₈), 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/O₉through I/O₁₆) is written into the location

specified on the address pins (A₀through A₁₅).

— t_AA= 8 ns (Commercial & Industrial)

— t_AA= 12 ns (Automotive)

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/O₁to I/O₈. If Byte High Enable (BHE) is

LOW, then data from memory will appear on I/O₉to I/O₁₆. See

the truth table at the end of this data sheet for a complete

description of Read and Write modes.

• CMOS for optimum speed/power

• Low active power: 345 mW (max.)

• Automatic power-down when deselected

• Independent control of upper and lower bits

• Available in Pb-free and non Pb-free 44-pin 400-Mil SOJ

44-pin TSOP II and 48-ball FBGA packages

The input/output pins (I/O₁through I/O₁₆) 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 CY7C1021CV33 is available in 44-pin 400-Mil wide SOJ,

44-pin TSOP II and 48-ball FBGA packages.
