8 CMOS FLASH MEMORY
1. GENERAL DESCRIPTION
The W39L512 is a 512Kbit, 3.3-volt only CMOS flash memory organized as 64K
×
8 bits. For flexible
erase capability, the 512Kbits of data are divided into 16 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 V
PP
is not required. The unique cell architecture of the
W39L512 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.
