Description
The AT49LH002 is a Flash memory device designed for use in PC and notebook BIOS
applications. The device complies with version 1.1 of Intel鈥檚 LPC Interface Specifica-
tion, providing support for both FWH and LPC memory read and write cycles. The
device can also automatically detect the memory cycle type to allow the AT49LH002
to be used as a FWH with Intel chipsets or as an LPC Flash with non-Intel chipsets.
