W39L010 Datasheet, PDF (3/27 Pages) Winbond – 128K X 8 CMOS FLASH MEMORY

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
standard 3.3V power supply. A 12-volt VPP is not required. The unique cell architecture of the
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.
