256K (32K x 8) Static RAM

Features

Functional Description^[1]

• Temperature Ranges

The CY62256VN family is composed of two high-performance

CMOS static RAM’s organized as 32K words by 8 bits. Easy

memory expansion is provided by an active LOW chip enable

(CE) and active LOW output enable (OE) and tri-state drivers.

These devices have an automatic power-down feature,

reducing the power consumption by over 99% 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

• Speed: 70 ns

An active LOW write enable signal (WE) controls the

writing/reading operation of the memory. When CE and WE

inputs are both LOW, data on the eight data input/output pins

(I/O₀through I/O₇) is written into the memory location

addressed by the address present on the address pins (A₀

through A₁₄). Reading the device is accomplished by selecting

the device and enabling the outputs, CE and OE active LOW,

while WE remains inactive or HIGH. Under these conditions,

the contents of the location addressed by the information on

address pins are present on the eight data input/output pins.

• Low voltage range: 2.7V–3.6V

• Low active power and standby power

• Easy memory expansion with CE and OE features

• TTL-compatible inputs and outputs

• Automatic power-down when deselected

• CMOS for optimum speed/power

• Available in standard Pb-free and non Pb-free 28-lead

(300-mil) narrow SOIC, 28-lead TSOP-I and 28-lead

Reverse TSOP-I packages

The input/output pins remain in a high-impedance state unless

the chip is selected, outputs are enabled, and write enable

(WE) is HIGH.
