GENERAL DESCRIPTION

The W49V002FA is a 2-megabit, 3.3-volt only CMOS flash memory organized as 256K

× 8 bits. The

not required. The unique cell architecture of the W49V002FA results in fast program/erase operations

with extremely low current consumption. This device can operate at two modes, Programmer bus

interface mode and FWH bus interface mode. As in the Programmer interface mode, it acts like the

traditional flash but with a multiplexed address inputs. But in the FWH interface mode, this device

complies with the Intel FWH specification. The device can also be programmed and erased using

standard EPROM programmers.
