Revision A4
1. GENERAL DESCRIPTION
The W39V080A is an 8-megabit, 3.3-volt only CMOS flash memory organized as 1M
×
8 bits. For
flexible erase capability, the 8Mbits of data are divided into 16 uniform sectors of 64 Kbytes. The
device can be programmed and erased in-system with a standard 3.3V power supply. A 12-volt VPP
is required for accelerated program. The unique cell architecture of the W39V080A 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. The device can also be
programmed and erased using standard EPROM programmers.
