×
16 CMOS 3.3V FLASH MEMORY
GENERAL DESCRIPTION
The W49L102 is a 1-megabit, 3.3-volt only CMOS flash memory organized as 64K
×
16 bits. 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 W49L102 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 using standard EPROM programmers.
