the FWH interface (Intel Spec rev1.1) used
in PC BIOS applications
– 5-signal communication interface
supporting Read and Write operations
– 5 additional general-purpose inputs for
platform design flexibility
– Synchronized with 33 MHz PCI clock
■
16 blocks of 64 Kbytes
– 13 blocks of 64 Kbytes each
– 3 blocks, subdivided into 16 uniform
sectors of 4 Kbytes each
Two blocks at the top and one at the bottom
(M50FLW080A)
One block at the top and two at the bottom
(M50FLW080B)
■
Enhanced security
