• Manufacturer Part Number: W39V040FBP
• Description: 512K X 8 CMOS FLASH MEMORY WITH FWH INTERFACE
• Manufacturer: WINBOND [Winbond]

1. GENERAL DESCRIPTION
The W39V040FB is a 4-megabit, 3.3-volt only CMOS flash memory organized as 512K
flexible erase capability, the 4Mbits of data are divided into 8 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 W39V040FB 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.
