Applications
The TMS320VC5441PGF is designed for high-throughput embedded DSP applications such as multi-channel voice processing, telecom base-station modems, and medical imaging signal chains. Its quad-core architecture allows independent processing of 4 audio or data channels simultaneously, making it well suited for VoIP gateways and software-defined radio front-ends. Industrial control systems requiring real-time FFT and filter processing at 133 MHz also benefit from its fixed-point efficiency.

Frequently Asked Questions
What clock frequency does the TMS320VC5441PGF support, and how does its quad-core layout help multi-channel DSP workloads?
The TMS320VC5441PGF operates at up to 133 MHz per core, and its 4 independent fixed-point DSP cores can process separate data streams concurrently, yielding an effective throughput of 532 MMAC for parallel multi-channel workloads such as 4-channel audio filtering or beamforming arrays.
For a telecom line-card design, how does the TMS320VC5441PGF's 19-bit address bus affect memory expansion options?
The 19-bit address bus provides a 512 K-word (1 MB) external addressable space per core, sufficient for large coefficient tables and data buffers used in voice codecs like G.711 or G.729. Designers can attach external SRAM or SDRAM to each core's bus for expanded working memory without a memory management unit.
When is TMS320VC5441PGF a stronger choice than a single-core TMS320VC5416 for a multi-channel VoIP gateway?
The TMS320VC5441PGF's 4 DSP cores handle 4 independent voice channels at 133 MHz each, whereas a single-core TMS320VC5416 at 160 MHz can sustain only 1 to 2 full-rate G.729 channels. For a 4-port VoIP gateway, using the quad-core part reduces chip count from 4 single-core DSPs to 1 device, cutting PCB area by roughly 60%.
Does TMS320VC5441PGF support JTAG boundary scan, and how does this benefit production test?
Yes, the device includes IEEE 1149.1 JTAG boundary scan across all 5 cores, allowing automated test equipment to verify interconnect integrity on 100% of boards during production testing. This eliminates the need for bed-of-nails ICT fixtures for the DSP section, reducing test fixture cost by up to 40%.
What supply voltages does the TMS320VC5441PGF require, and what does the 3.3 V requirement mean for power-supply design?
The TMS320VC5441PGF requires both a core supply (typically 1.6 V) and a separate 3.3 V I/O supply, meaning the power tree must include at least 2 regulated rails. A sequenced power-up with core rail first avoids latch-up; the 3.3 V rail must deliver sufficient current for the 16-bit external data bus I/O buffers driving off-chip memory.
