TMS320UC5409PGE-80

Digital Signal Processor Dsp Overview

The TMS320UC5409PGE-80 is a fixed-point digital signal processor based on the C54x core, housed in a 144-pin LQFP package. It operates at a maximum clock frequency of 80 MHz with a 12.5-ns instruction execution time. The device features a 16-bit data bus and an advanced modified Harvard architecture with separate program and data buses. Power requirements include a 1.8-V core supply (CVDD) and a 1.8-V to 3.6-V I/O supply (DVDD). On-chip memory consists of 16K x 16-bit ROM and 32K x 16-bit dual-access RAM.

Digital Signal Processor Dsp Feature Summary

• Advanced Multibus Architecture: One program memory bus and three separate 16-bit data memory buses for high parallelism.
• Arithmetic Logic Unit: 40-bit ALU with a barrel shifter, two 40-bit accumulators, and a 17x17-bit multiplier coupled to a 40-bit adder for single-cycle MAC operations.
• On-Chip Memory: Includes 16K x 16-bit maskable ROM with bootloader support and 32K x 16-bit dual-access RAM (DARAM).
• Peripherals: Features three multichannel buffered serial ports (McBSPs), an enhanced 8-bit parallel host-port interface, a 16-bit timer, and a six-channel DMA controller.

Digital Signal Processor Dsp Applications

• Low-power, high-performance digital signal processing applications.
• Systems requiring mixed voltage configurations with sub-3V operation.
• Multiprocessor systems utilizing branch control and external flag signals.

Digital Signal Processor Dsp Procurement Notes

Verify that the PGE suffix corresponds to the 144-pin Plastic Thin Quad Flatpack (TQFP) package as specified in the datasheet. Confirm the -80 speed grade matches the required 80 MHz operating frequency. Ensure power supply designs accommodate the separate 1.8-V core (CVDD) and 1.8-V to 3.6-V I/O (DVDD) rails.

Digital Signal Processor Dsp Selection Notes

Select this component for applications needing single-cycle multiply/accumulate performance with low power consumption. The wide I/O voltage range allows operation with a single 1.8-V supply or dual supplies, eliminating external level-shifters. Consider the 144-pin LQFP package constraints for PCB layout if surface-mount assembly is required.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320C54x family of fixed-point DSPs. The UC5409 variant specifically offers 80 MHz performance, distinguishing it from other speed grades like the 120 MHz VC5409. The PGE suffix denotes the LQFP package type, while GGU would indicate a BGA package.

Digital Signal Processor Dsp Replacement Considerations

Compatible parts within the same family include the TMS320VC5409 series for higher clock speeds or the TMS320LC5409 for different power profiles. Package variations such as the TMS320UC5409GGU offer the same functionality in a BGA format.
