16 Mbit LPC Flash
SST49LF160C
Advance Information
Multiple Device Selection
Multiple LPC flash devices may be strapped to increase
memory densities in a system. The four ID pins, ID[3:0],
allow up to 16 devices to be attached to the same bus by
using different ID strapping in a system. BIOS support, bus
loading, or the attaching bridge may limit this number. The
boot device must have an ID of 0000b (determined by
ID[3:0]); subsequent devices use incremental numbering.
Equal density must be used with multiple devices.
Multiple Device Selection for
LPC Memory Cycle
For LPC Memory Read/Write cycles, ID information is
included in the address bits of every cycle. The ID bits in
the address field are inverse of the hardware strapping.
The address bits [A 25 :A 23 , A 21 ] are used to select the
device with proper IDs. See Table 7 for device selection
configurations. The SST49LF160C will compare these bits
with ID[3:0]’s strapping values. If there is a mismatch, the
device will ignore the remainder of the cycle.
