TMS320VC5509AGBB

Digital Signal Processor Dsp Overview

The TMS320VC5509AGBB is a fixed-point digital signal processor from Texas Instruments based on the C55x DSP CPU core. It features a 179-ball ball grid array (BGA) package and supports clock rates up to 200 MHz with a 1.6 V core voltage, delivering 400 MIPS performance. The device integrates 128 KB of on-chip RAM, including dual-access and single-access memory blocks, alongside 64 KB of ROM. Key peripherals include three McBSPs, an I2C interface, USB full-speed support, and a DMA controller. It operates within a temperature range of -40°C to +85°C.

Digital Signal Processor Dsp Feature Summary

• High-performance C55x DSP architecture with up to 200 MHz operation
• Integrated memory: 128 KB RAM (DARAM/SARAM) and 64 KB ROM
• Dual MAC units providing 400 MMACS throughput
• Comprehensive peripheral set including USB, MMC/SD, and multiple serial ports

Digital Signal Processor Dsp Applications

• Real-time minimum mean-square error turbo-equalization in mobile terminals
• Audio processing applications such as instrument tuners and noise reduction
• Portable multimedia devices requiring low-power signal processing

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'BB' against the manufacturer's nomenclature guide to confirm pinout and thermal specifications for the BGA package. Ensure that design files reference the correct 179-terminal GHH/ZHH package dimensions and electrical characteristics for the selected speed grade.

Digital Signal Processor Dsp Selection Notes

Select this model when a compact BGA footprint is required compared to the LQFP alternative. Confirm that the target application utilizes the internal boot configuration via GPIO pins or external parallel bus interfaces as defined in the memory map. Validate power supply requirements for the 1.6 V core voltage at maximum frequency.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320VC5509A family, which implements the enhanced C55x architecture. It shares functional similarities with other variants like the APGE and AZAY packages but differs in physical form factor and terminal count. The device is designed for high-efficiency digital signal processing in battery-operated systems.

Digital Signal Processor Dsp Replacement Considerations

Direct pin-compatible replacements within the same package are limited. Consider the TMS320VC5509AZAYR for BGA alternatives if pin mapping aligns, though verification of the specific suffix electrical parameters is required.
