Revision A4
1. GENERAL DESCRIPTION
The W49L401(T) is a 4-megabit, 3.3-volt only CMOS flash memory organized as 256K
×
16 bits. The
device can be programmed and erased in-system with a standard 3.3-volt power supply. A 12-volt V
PP
is not required. The unique cell architecture of the W49L401(T) 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.
