Revision A1
GENERAL DESCRIPTION
The W29S201 is a 2-megabit, 5-volt only CMOS flash memory organized as 128K
×
16 bits. The
W29S201 supports both assynchronous & high performance synchronous burst read modes. The device
can be programmed and erased in-system with a standard 5V power supply. A 12-volt V
PP
is not
required. The unique cell architecture of the W29S201 results in fast program/erase operations with
extremely low current consumption (compared to other comparable 5-volt flash memory products). The
device can also be programmed and erased using standard EPROM programmers.
