16 Mbit LPC Serial Flash
SST49LF016C
Multiple Device Selection
Multiple LPC serial 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 sup-
port, bus loading, or the attaching bridge may limit this num-
ber. The boot device must have an ID of 0000b (determined
by ID[3:0]); subsequent devices use incremental number-
ing. Equal density must be used with multiple devices.
Multiple Device Selection for
Firmware Memory Cycle
For Firmware Memory Read/Write cycles, hardware strap-
ping values on ID[3:0] must match the values in IDSEL
field. The SST49LF016C 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. See Table 7 for Multi-
ple Device Selection Configuration.
