TMS320VC5509PGE31

Digital Signal Processor Dsp Overview

The TMS320VC5509PGE31 is a fixed-point digital signal processor from Texas Instruments, utilizing the C55x DSP core architecture. It operates at clock frequencies up to 200 MHz and delivers 400 MIPS performance. The device features an enhanced Harvard bus structure with separate program and data buses. On-chip memory includes dual-access RAM (DARAM) and single-access RAM (SARAM). Key peripherals include two Multi-Channel Buffered Serial Ports (McBSP), a Universal Serial Bus (USB) full-speed slave interface, an I²C interface, and a Direct Memory Access (DMA) controller. The component is housed in a 144-pin Low-Profile Quad Flatpack (LQFP) package.

Digital Signal Processor Dsp Procurement Notes

Verify the specific ordering suffix '31' against the manufacturer's current nomenclature guide to confirm package type and temperature rating. Ensure compatibility with development tools such as Code Composer Studio versions supporting the C55x family. Confirm lead times and availability through authorized distributors as production status may vary.

Digital Signal Processor Dsp Selection Notes

Select this model for applications requiring low-power fixed-point signal processing with integrated USB connectivity. Compare pin assignments and memory maps against system requirements. Verify that the 144-pin LQFP package fits the PCB layout constraints. Check peripheral availability if specific interfaces like MMC/SD or additional serial ports are required.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320VC5509 family within the TI C5000 DSP series. It shares architectural similarities with other C55x processors but offers specific memory configurations and peripheral sets tailored for cost-sensitive embedded applications. The PGE suffix denotes the 144-pin LQFP package variant.

Digital Signal Processor Dsp Replacement Considerations

Consult the official cross-reference documentation for compatible upgrades. Potential alternatives within the same family should be evaluated based on pin compatibility, memory size, and peripheral availability. Ensure software migration paths are considered when switching between different DSP cores.
