PDM31096

4 Megabit 3.3V Static RAM

512K x 8-Bit

Features

Description

The PDM31096 is a high-performance CMOS static

RAM organized as 524,288 x 8 bits. Writing is

accomplished when the write enable (WE) and chip

enable CE inputs are both LOW. Reading is

accomplished when WE remains HIGH and CE and

OE are both LOW.

The PDM31096 operates from a single +3.3V power

supply and all the inputs and outputs are fully TTL-

compatible.

The PDM31096 is available in a 36-pin 400-mil plas-

tic SOJ package and a 44-pin plastic TSOP (II)

package.

High-speed access times

Com’l: 8, 10, 12, 15, and 20 ns

NOTE: 1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause

permanent damage to the device. This is a stress rating only and functional operation

of the device at these or any other conditions above those indicated in the operational

sections of this speciﬁcation is not implied. Exposure to absolute maximum rating

conditions for extended periods may affect reliability.

2. Appropriate thermal calculations should be performed in all cases and speciﬁcally for

those where the chosen package has a large thermal resistance (e.g., TSOP). The cal-

culation should be of the form

: T

= T

+ P *

where T

is the ambient temperature, P

is average operating power and

the thermal resistance of the package. For this

product, use the following
