Preliminary W49V002A
256K x 8 CMOS FLASH MEMORY
WITH LPC INTERFACE
GENERAL DESCRIPTION
The W49V002A is a 2
-megabit, 3.3-volt only CMOS flash memory organized as 256K
脳
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 W49V002A results in fast program/erase operations with
extremely low current consumption. This device can operate at two modes, Programmer bus interface
mode and LPC bus interface mode. As in the Programmer interface mode, it acts like the traditional
flash but with a multiplexed address inputs. But in the LPC interface mode, this device complies with the
Intel LPC specification 1.0. The device can also be programmed and erased using standard EPROM
programmers.
