W39L010

1. GENERAL DESCRIPTION

The W39L010 is a 1Mbit, 3.3-volt only CMOS flash memory organized as 128K

× 8 bits. For flexible

erase capability, the 1Mbits of data are divided into 32 small even pages with 4 Kbytes. The byte-wide

(

× 8) data appears on DQ7 − DQ0. The device can be programmed and erased in-system with a

W39L010 results in fast program/erase operations with extremely low current consumption (compared

to other comparable 3.3-volt flash memory products). The device can also be programmed and

erased by using standard EPROM programmers.
