description
The TI380PCI provides a glueless interface between a TI380C2x commprocessor and the PCI bus. The
TI380PCI transfers information / data between the PCI bus and the TI380C2x System Interface (SIF ) using any
of these three methods:
D Direct memory access (DMA)
D Direct input /output (DIO)
D Pseudo-direct memory access (PDMA)
DMA (or PDMA) transfers all data between host memory (by way of the PCI Local Bus) and TI380C2x local
memory. DIO accesses are typically used to load software into TI380C2x local memory and for initializing the
TI380C2x.
The TI380PCI conforms to the PCI standards found in “PCI Local Bus Specification,” Revision 2.0.^†
The TI380PCI is available in a 144-pin EIAJ plastic quad flat package (PCM suffix) and is rated from 0_C to
70_C.
† _{The “PCI Local Bus Specification”, Revision 2.0, and the TI380C2x series of data sheets (literature numbers SPWS012, SPWS013, and}
SPWS014) should be used as references to this document.
