TMS320VC5503ZHH

Digital Signal Processor Dsp Overview

The TMS320VC5503ZHH is a fixed-point digital signal processor from Texas Instruments, utilizing the C55x CPU core architecture. It features a Harvard bus structure with one program bus and multiple data buses to enable high performance at low power. The device supports clock speeds up to 200 MHz when operating at a CVDD of 1.6 V. Key internal resources include dual-access RAM (DARAM) and read-only memory (ROM). Peripherals consist of three multichannel buffered serial ports (McBSPs), an enhanced host-port interface (EHPI), a direct memory access (DMA) controller, and general-purpose I/O.
