TMS320C6474FZUNA

Digital Signal Processor Dsp Overview

The TMS320C6474FZUNA is a multicore digital signal processor from Texas Instruments, featuring three independent C64x+ DSP cores operating at up to 1.2 GHz with a 0.83-ns instruction cycle time. It utilizes a 0.065-μm CMOS process and includes SmartReflex technology for adaptive core voltage scaling between 0.9 V and 1.2 V. The device integrates 32 KB L1P program cache, 32 KB L1D data cache, and 64 KB L3 ROM per megamodule. Key peripherals include two Serial RapidIO links, a 1000 Mbps Ethernet MAC, an antenna interface supporting OBSAI/CPRI standards, and a DDR2 memory controller.

• Integrated Enhanced Viterbi-Decoder Coprocessor (VCP2) and Turbo Decoder Coprocessor (TCP2)
• Antenna Interface (AIF) with six high-speed serial links compliant with OBSAI RP3 and CPRI
• Two 1x Serial RapidIO v1.2 links supporting 1.25 Gbps to 3.125 Gbps rates

Digital Signal Processor Dsp Applications

• Telecommunications infrastructure base stations
• Video and imaging systems requiring high-bandwidth interconnects
• Medical imaging equipment
• Radar and electronic warfare signal processing

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade and temperature rating required for the application, as the C6474 family includes 850 MHz, 1 GHz, and 1.2 GHz variants with distinct commercial and extended temperature ranges. Confirm that the ZUN suffix corresponds to the 561-pin BGA package with 0.8-mm ball pitch. Ensure design specifications account for the mandatory use of a heatsink and implementation of the SmartReflex solution for proper thermal and voltage management.

Digital Signal Processor Dsp Selection Notes

Select this component when high-performance multicore processing is combined with specialized channel decoding needs. The integrated VCP2 and TCP2 accelerators significantly reduce CPU load for 3GPP-compliant turbo and Viterbi decoding tasks. Consider the 561-pin BGA footprint and 0.065-μm process requirements during PCB layout. Verify compatibility with existing C6000 platform software tools if migrating from previous generations.

Digital Signal Processor Dsp Part Context

The TMS320C6474 belongs to the TMS320C64x+ DSP family within the broader TMS320C6000 platform. It represents a third-generation high-performance VLIW architecture designed for upward code compatibility with earlier C6000 devices. The FZUNA designation indicates a specific speed bin and package configuration within the C6474 product line, which also includes CUN and GUN package options.
