description

The TI380PCIA provides a glueless interface between a TI380C2x commprocessor and the PCI bus (see Figure 1). The TI380PCIA transfers information/data between the PCI bus and the TI380C2x system interface (SIF) using any of these three methods:

• Direct memory access (DMA)
• Direct input/output (DIO)
• 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 TI380PCIA conforms to the PCI standards found in "PCI Local Bus Specification," Revision 2.0.^§

The TI380PCIA is available in a 144-pin JEDEC plastic quad flat package (PCM suffix) and is rated from 0°C to 70°C. It is a drop-in replacement for the TI380PCI.
