Description
The W39V040FC is a 4-megabit, 3.3-volt only CMOS flash memory organized as 512K?x 8 bits. For flexible erase capability, the 4Mbits of data are divided into 16 x 8 Kbytes pages and 6 x 64 Kbytes sectors or 8 x 64 Kbytes sectors. 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 W39V040FC results in fast program/erase operations with extremely low current consumption. This device can operate at two modes, Programmer bus interface mode, Firmware Hub (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.
