Revision A2
GENERAL DESCRIPTION
The W49V002FA is a 2-megabit, 3.3-volt only CMOS flash memory organized as 256K
×
8 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 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.
