1. GENERAL DESCRIPTION
The W39V080FA 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 W39V080FA 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.
