TMS320UC5402PGE-80

Digital Signal Processor Dsp Overview

The TMS320UC5402PGE-80 is a fixed-point digital signal processor from the C54x family, manufactured by Texas Instruments. It features a 16-bit data bus and operates at a maximum clock frequency of 80 MHz, delivering 80 MMACS performance with a 12.5-ns instruction execution time. The device utilizes a modified Harvard architecture with one program memory bus and three data memory buses. Key on-chip resources include 4K x 16-bit ROM and 16K x 16-bit dual-access RAM (DARAM). It supports a 1.8-V core supply and I/O voltages ranging from 1.8 V to 3.6 V. The component is housed in a 144-pin Low-Profile Quad Flatpack (LQFP) package.

Digital Signal Processor Dsp Feature Summary

• Advanced Multibus Architecture: Features one program memory bus and three separate 16-bit data memory buses for high parallelism.
• High-Performance Arithmetic: Includes a 40-bit ALU, a 17x17-bit parallel multiplier coupled to a 40-bit dedicated adder, and a Compare, Select, and Store Unit (CSSU).
• Integrated Peripherals: Equipped with two McBSPs, an enhanced 8-bit parallel host-port interface (HPI8), six-channel DMA controller, two timers, and a software-programmable wait-state generator.
• Power Efficiency: Supports IDLE1, IDLE2, and IDLE3 power-down modes and allows operation with a single 1.8-V supply or dual supplies.

Digital Signal Processor Dsp Applications

• Low-power, high-performance digital signal processing systems.
• Mixed voltage systems requiring flexible I/O voltage configurations (1.8 V to 3.6 V).
• Applications utilizing the on-chip bootloader stored in ROM.

Digital Signal Processor Dsp Procurement Notes

Verify that the ordering suffix 'PGE' corresponds to the 144-pin LQFP package as specified in the datasheet. Confirm the speed grade matches the required 80 MHz operational frequency. Ensure the design accounts for the 1.8-V core voltage and the 1.8-V to 3.6-V I/O voltage range. Check for RoHS compliance status in the latest manufacturer documentation.

Digital Signal Processor Dsp Selection Notes

Select this component when a 16-bit DSP with 80 MIPS performance is required. The UC5402 variant includes 4K ROM with a bootloader, distinguishing it from variants without on-chip ROM. Consider the LQFP package if BGA soldering capabilities are unavailable. Verify that the system can support the specific power sequencing requirements between the core (CVDD) and I/O (DVDD) supplies to ensure long-term reliability.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320VC54xx series of fixed-point DSPs. The 'UC' designation indicates the inclusion of on-chip ROM with a bootloader. The 'PGE' suffix identifies the 144-pin LQFP package. The '-80' suffix denotes the 80 MHz speed grade. This model is distinct from the VC5416, which offers higher memory capacity and a 120 MHz speed grade.
