PCI2040PGE

The Texas Instruments PCI2040PGE is a PCI to DSP bridge controller that facilitates a glueless connection between host port interfaces (HPI) of TMS320C54X or TMS320C6X DSPs and the PCI bus. This device provides a PCI bus target interface compliant with the PCI Local Bus Specification.

Key electrical characteristics include a supply voltage range of 3.3V to 5V and an operating temperature range of 0°C to 70°C. The controller supports a maximum PCI bus frequency of 33 MHz and offers a speed of 0.033 Gbps. It features a universal PCI interface compatible with 3.3-V to 5-V signaling environments.

The PCI2040PGE is housed in a 144-pin LQFP package, measuring 20x20 mm. It supports single-word reads and writes, write transaction posting for improved PCI bus performance, and provides direct access to program and control external devices connected to the PCI2040. Additional interfaces include a serial ROM interface and a 16-bit general-purpose bus (GPB).

This bridge controller is suitable for applications requiring high-performance data transfer between DSP processors and the PCI bus, offering a robust solution for embedded systems and signal processing designs.
