operation
Operation of the SMQ320C32 is identical to the ’320C30 and ’320C31 digital signal processors, with the
exception of an enhanced external memory interface and the addition of two CPU power-management modes.
external memory interface
The SMQ320C32 has a configurable external memory interface with a 24-bit address bus, a 32-bit data bus,
and three independent multi-function strobes. The flexibility of this unique interface enables product designers
to minimize external memory-chip count.
