TMS320VC5404PGE

Digital Signal Processor Dsp Overview

The TMS320VC5404PGE is a fixed-point digital signal processor from the Texas Instruments TMS320C54x family, housed in a 144-pin LQFP package. It operates with a maximum clock frequency of 80 MHz and utilizes a 1.8 V core voltage alongside 3.3 V I/O levels. The architecture features an improved Harvard structure with separate program and data buses, supporting up to 1M x 16-bit external memory addressing. Internal resources include 8 KB of dual-port RAM for data storage. The device supports multiple low-power modes and includes peripherals such as two McBSPs, an HPI8 interface, six-channel DMA, and two 16-bit timers.

• 1.8 V core supply with 3.3 V tolerant I/O pins
• Peripheral set includes dual McBSP, HPI8, 6-channel DMA, and dual 16-bit timers

Digital Signal Processor Dsp Applications

• Modems and communication equipment
• Industrial motor control systems
• Consumer audio processing devices

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade suffix (e.g., PGE80) against the required clock frequency, as the base model number may encompass multiple frequency variants. Confirm RoHS compliance status through the manufacturer's official documentation prior to procurement. Ensure ESD handling protocols are followed due to the sensitivity of the CMOS technology used in the LQFP-144 package.

Digital Signal Processor Dsp Selection Notes

Select this component when an 80 MHz processing speed is sufficient for the application, offering a cost-effective alternative to higher-speed C54x variants like the VC5416. Consider the 8 KB internal RAM limitation; applications requiring larger on-chip memory should evaluate the VC5409A or VC5416 models. Verify that the 1.8 V core voltage requirement aligns with the system's power delivery infrastructure.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320VC5404 series, which serves as a lower-frequency variant within the broader C54x family. It shares architectural similarities with the VC5402 and VC5409A but differs in clock speed and memory configuration. The 'PGE' suffix indicates a Green (RoHS compliant) plastic quad flatpack package with an exposed pad, suitable for surface-mount assembly.

Digital Signal Processor Dsp Replacement Considerations

Direct pin-compatible replacements within the same package include other C54x devices such as the TMS320VC5402PGE or TMS320VC5409APGE, provided the clock speed and memory requirements are met. Cross-family replacements require significant schematic and software modifications.
