Product Summary

The TMS320VC5509PGE31 is a fixed-point digital signal processor. It is based on the TMS320C55x DSP generation CPU processor core. The C55x DSP architecture achieves high performance and low power through increased parallelism and total focus on reduction in power dissipation. The CPU of the TMS320VC5509PGE31 supports an internal bus structure that is composed of one program bus, three data read buses, two data write buses, and additional buses dedicated to peripheral and DMA activity. These buses of TMS320VC5509PGE31 provides the ability to perform up to three data reads and two data writes in a single cycle.
