TMS320VC5407PGE

Digital Signal Processor Dsp Overview

The TMS320VC5407PGE is a fixed-point digital signal processor from the Texas Instruments TMS320C54x family, housed in a 144-pin LQFP package. It operates at a maximum clock frequency of 90 MHz with a 16-bit data bus width and a 1.8V core supply voltage. The device integrates 8 kB of program ROM, 32 kB of dual-port RAM, and supports up to 1 MB of external memory expansion. Key architectural features include an enhanced Harvard architecture with four parallel buses, a 40-bit arithmetic logic unit, and a 17x17-bit multiplier. I/O pins are compatible with 3.3V logic levels.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix for temperature range and package variant against the manufacturer datasheet. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Check for active production status or obsolescence notices directly from Texas Instruments documentation.

Digital Signal Processor Dsp Selection Notes

Select this component when a low-power C54x solution with integrated ROM is required. Ensure the design accommodates the 1.8V core supply and 3.3V I/O requirements. Verify that the 90 MHz performance meets the algorithmic throughput needs compared to higher-speed variants like the VC5416.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320VC540x series, which serves as a cost-effective entry point into the C54x DSP portfolio. It shares architectural similarities with the VC5402 and VC5410 but offers distinct memory configurations and clock speeds tailored for specific embedded control and signal processing applications.

Digital Signal Processor Dsp Replacement Considerations

Direct pin-compatible replacements within the same package may include other members of the TMS320VC540x family, such as the TMS320VC5402 or TMS320VC5410, provided memory sizes and clock frequencies align with system requirements.
