TMS320VC549GGU-80

Digital Signal Processor Dsp Overview

The TMS320VC549GGU-80 is a fixed-point digital signal processor from the Texas Instruments C54x family, designed for low-power embedded applications. It features a high-performance CPU with a maximum clock frequency of 80 MHz and utilizes a Harvard architecture with separate program and data buses. The device integrates 16 kB of on-chip ROM, 192 kB of double-mapped RAM, and 2 kB of single-mapped RAM. Operating at a core voltage of 1.5 V and I/O voltage of 3.3 V, it is housed in a 176-pin Plastic Quad Flat Package (PQFP) suitable for surface-mount installation.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'GGU-80' against the manufacturer's official datasheet to confirm pin compatibility and electrical specifications. Ensure that the required mask ROM content is supported by the supplier, as this variant contains factory-programmed code. Confirm RoHS compliance status and moisture sensitivity level prior to assembly planning.

Digital Signal Processor Dsp Selection Notes

Select this component when an 80 MHz processing speed is required within the C54x ecosystem. Compare memory requirements against the available 192 kB RAM and 16 kB ROM; if larger storage is needed, consider variants with external memory interfaces or different package options. Verify that the PQFP-176 footprint aligns with the PCB design constraints.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320VC549 series, which represents an enhanced version of the C54x DSP line. The 'V' indicates a 3.3 V I/O interface, while the 'C' denotes commercial temperature range operation. The GGU suffix specifies the 176-pin PQFP package, and -80 indicates the 80 MHz speed grade.

Digital Signal Processor Dsp Replacement Considerations

Direct pin-compatible replacements within the same speed grade may include other TMS320VC549 variants with different package codes. For higher performance, the TMS320VC5416 series offers faster speeds but requires architectural adaptation. Always verify software compatibility and peripheral register mappings before substituting.
