What are the key features of TMS320VC549PGE-80?

  • 16-bit fixed-point DSP core with barrel shifter and multiple internal buses enabling high-throughput signal processing at up to 80 MHz
  • 23-bit address bus and 16-bit external data bus supporting large memory maps for complex algorithm storage and coefficient tables
  • Dual-voltage operation requiring 3.3 V I/O supply with a separate core supply, reducing dynamic power consumption in embedded DSP designs

What is TMS320VC549PGE-80 used for?

The TMS320VC549PGE-80 is suited for telecom line-card modems, voice processing units, and industrial DSP applications where a 16-bit fixed-point processor at 80 MHz provides the necessary MIPS for real-time filtering and coding algorithms. Its large 23-bit address space supports firmware-heavy signal processing tasks such as echo cancellation, DTMF detection, and speech encoding in PBX and VoIP equipment. The QFP package and JTAG boundary scan capability also make it practical for high-reliability embedded designs requiring in-system debug and test.

Frequently Asked Questions

What clock frequency does TMS320VC549PGE-80 operate at, and what DSP throughput does that provide for real-time filtering?

TMS320VC549PGE-80 operates at up to 80 MHz with a 16-bit fixed-point architecture and multiple internal buses, enabling approximately 80 MIPS of throughput for real-time FIR filter, FFT, and convolution tasks in telecom modem and audio processing applications.

How does the 23-bit address bus of TMS320VC549PGE-80 compare to earlier C5x family DSPs for algorithm storage?

The 23-bit address bus allows TMS320VC549PGE-80 to directly access up to 8 MB of memory space, significantly more than the 16-bit address range of older C5x devices. This is important when storing large coefficient tables for multi-band equalizers, echo cancellers, or codec libraries in 3.3 V DSP subsystems.

What dual-supply design consideration applies when using TMS320VC549PGE-80 on a 3.3 V logic board?

TMS320VC549PGE-80 requires both a 3.3 V I/O supply and a separate lower-voltage core supply, so the board must include a regulated core LDO. The 3.3 V I/O bus interfaces directly with standard SRAM, FLASH, and peripheral logic, while the core supply is sequenced to power up first to prevent latch-up during initialization.
