W26020A

128K ´ 16 HIGH-SPEED CMOS STATIC RAM

GENERAL DESCRIPTION

The W26020A is a high-speed, low-power CMOS static RAM organized as 131,072 ´ 16 bits that

operates on a single 5-volt power supply. This device is manufactured using Winbond's high

performance CMOS technology.

The W26020A has an active low chip select, separate upper and lower byte selects, and a fast output

enable. No clock or refreshing is required. Separate byte select controls (LB and UB ) allow

individual bytes to be written and read. LB controls I/O1-I/O8, the lower byte. UB controls I/O9-

I/O16, the upper byte. This device is well suited for use in high-density, high-speed system

applications.

FEATURES

· High speed access time: 20/25 nS (max.)

· Low power consumption:

- Active: 1.5W (max.)

· All inputs and outputs directly TTL compatible

· Three-state outputs

· Data byte control

· Single +5V power supply

· Fully static operation

- LB (I/O1- I/O8), UB (I/O9- I/O16)

· Available packages: 44-pin type two TSOP

- No clock or refreshing
