W26010A

´ 16 HIGH-SPEED CMOS STATIC RAM

64K

GENERAL DESCRIPTION

The W26010A is a high-speed, low-power CMOS static RAM organized as 65,536 ´ 16 bits that

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

performance CMOS technology.

The W26010A 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: 15/20/25 nS (max.)

· Low power consumption:

- Active: 1.3W (max.)

· All inputs and outputs directly TTL compatible

· Three-state outputs

· Data byte control

· Single +5V power supply

· Fully static operation

- No clock or refreshing

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

· Available packages: 44-pin 400 mil SOJ and

Type II TSOP
