SM320VC5409GGU10EP

Digital Signal Processor Dsp Overview

The SM320VC5409GGU10EP is a fixed-point digital signal processor based on the C54x core, manufactured by Texas Instruments. It features an advanced modified Harvard architecture with one program memory bus and three separate 16-bit data memory buses. The device includes a 40-bit arithmetic logic unit (ALU), a 17 × 17-bit parallel multiplier coupled to a 40-bit dedicated adder for single-cycle multiply/accumulate operations, and two address generators. On-chip memory consists of 16 kB ROM and 32 kB dual-access RAM. It operates at a maximum clock frequency of 100 MHz with a 10-ns instruction execution time, powered by a 1.8-V core supply (CVDD) and a 3.3-V I/O supply (DVDD).

Digital Signal Processor Dsp Feature Summary

• Advanced Modified Harvard Architecture: One program memory bus and three separate 16-bit data memory buses allow simultaneous access.
• High-Performance Arithmetic: Features a 40-bit ALU, barrel shifter, two independent 40-bit accumulators, and a non-pipelined single-cycle MAC unit.
• On-Chip Memory: Includes 16K x 16-bit ROM and 32K x 16-bit dual-access RAM.
• Controlled Baseline: Offers extended temperature performance from -40°C to 100°C, enhanced diminishing manufacturing sources support, and qualification pedigree.

Digital Signal Processor Dsp Applications

• Fixed-point digital signal processing applications requiring high parallelism.
• Systems utilizing the enhanced 8-bit parallel host-port interface.
• Embedded control environments needing software-programmable wait-state generation.

Digital Signal Processor Dsp Procurement Notes

Verify that the ordering suffix 'GGU' corresponds to the 144-pin Ball Grid Array package as specified in the datasheet. Confirm the top-side marking 'M5409GGUEP' matches the component received. Ensure the operating environment stays within the recommended voltage ranges of 1.8 V for CVDD and 3.3 V for DVDD.

Digital Signal Processor Dsp Selection Notes

Select this model when a controlled baseline with enhanced DMS support is required for long-term production. The GGU suffix indicates the specific BGA footprint compatible with LC548 and VC5410 devices. Verify that the system design supports the 1.8-V core voltage requirement distinct from the 3.3-V I/O voltage.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320C5000 DSP family, specifically the VC5409A series. The 'SM' prefix denotes the military/extended grade variant with controlled baseline manufacturing. It shares architectural similarities with other C54x processors but offers specific pinout compatibility with legacy LC548 designs via the GGU package.

Digital Signal Processor Dsp Replacement Considerations

The GGU package is footprint-compatible with the 'LC548, 'LC/VC549, and 'VC5410 devices. Verify electrical specifications and pin assignments before substituting with these related models.
