PRELIMINARY

CY62148V

512K x 8 Static RAM

Features

• 2.7V−3.6V operation

• CMOS for optimum speed/power

• Low active power

— 180 mW (max.)

• Low standby power (Commercial LL version)

— 54

µW

(max.)

• Automatic power-down when deselected

• TTL-compatible inputs and outputs

• Easy memory expansion with CE and OE options

an automatic power-down feature that reduces power con-

sumption by more than 99% when deselected.

Writing to the device is accomplished by taking chip enable

(CE) and write enable (WE) inputs LOW. Data on the eight I/O

pins (I/O

through I/O

) is then written into the location speci-

fied on the address pins (A

through A

Reading from the device is accomplished by taking chip en-

able (CE) and output enable (OE) LOW while forcing write en-

able (WE) HIGH for read. Under these conditions, the contents

of the memory location specified by the address pins will ap-

pear on the I/O pins.

The eight input/output 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), or during a write

operation (CE LOW, and WE LOW).

The CY62148V is available in a standard 32 pin 450-mil-wide

body width SOIC and 32 pin TSOPII packages.

Functional Description

The CY62148V is a high-performance CMOS static RAM or-

ganized as 524,288 words by 8 bits. Easy memory expansion

is provided by an active LOW chip enable (CE), an active LOW

output enable (OE), and three-state drivers. This device has
