• Manufacturer Part Number: w39l010
• Description: 128k X 8 Cmos Flash Memory
• Manufacturer: Winbond Electronics Corp America

1. GENERAL DESCRIPTION
The W39L010 is a 1Mbit, 3.3-volt only CMOS flash memory organized as 128K u 8 bits. For flexible
erase capability, the 1Mbits of data are divided into 32 small even pages with 4 Kbytes. The byte-wide
(u 8) data appears on DQ7  DQ0. The device can be programmed and erased in-system with a
standard 3.3V power supply. A 12-volt V
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.
