W24258

32K ´ 8 CMOS STATIC RAM

GENERAL DESCRIPTION

The W24258 is a normal speed, very low power CMOS static RAM organized as 32768 ´ 8 bits that

operates on a wide voltage range from 2.7V to 5.5V power supply. The W24258 family, W24258-

70LE and W24258-70LI, can meet requirement of various operating temperature. This device is

manufactured using Winbond's high performance CMOS technology.

FEATURES

- Standby: 6 mW (max.)/3V

25 mW (max.)/5V

· Access time: 70 nS (max.)/5V

100 nS (max.)/3V

· All inputs and outputs directly TTL compatible

· Three-state outputs

· Battery back-up operation capability

· Data retention voltage: 2V (min.)

· Packaged in 28-pin 600 mil DIP, 330 mil SOP

and standard type one TSOP (8 mm ´ 13.4

mm)

· Single 3V/5V power supply

· Fully static operation
