The Low Pin Count [LPC] Bus, may also be called PPC. This may be a legacy interface as the ISA and PCI buses are replaced by the PCIe interface. |
![]() 49LF040B Flash |
The SST 49LF040B, 4 Mbit Flash is an example of an IC using the Low Pin Count [LPC] interface. |
In LPC mode, communication between the Host and the
49LF040B occurs via the 4-bit I/O communication signals,
LAD[3:0] and LFRAME#.
The 49LF040B detects the start
of an LPC cycle by reading the START field contents; a
0000b indicates the beginning of an LPC memory cycle.
