Preliminary W26B02

´ 16 CMOS STATIC RAM

128K

GENERAL DESCRIPTION

The W26B02 is a normal-speed, very low-power CMOS static RAM organized as 131072 ´ 16 bits that

operates on a wide voltage range from 2.7V to 3.6V power supply. The W26B02, W26B02-LE and

W26B02-LI, can meet the requirement of various operating temperature. This device is manufactured

using Winbonds’ high performance CMOS technology.

FEATURES

· Low power consumption

· Access time: 70 nS

· 2.7V to 3.6V supply voltage

· Fully static operation

· Battery back-up operation capability

· Data retention voltage: 1.5V (min.)

· Data byte control

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

· All inputs and outputs directly TTL compatible

· Three-state outputs

· Available packages: 44-pin type two TSOP,

and TFBGA
