TMS320C6474FGUN2

Digital Signal Processor Dsp Overview

The TMS320C6474FGUN2 is a multicore digital signal processor from Texas Instruments, featuring three independent C64x+ DSP cores. Each core operates at frequencies up to 1.2 GHz with an instruction cycle time of 0.83 ns. The device utilizes a 65-nm CMOS process and includes on-chip memory comprising 32 KB L1P cache, 32 KB L1D cache, and 64 KB L3 ROM per core. It integrates specialized accelerators such as the VCP2 and TCP2 for channel decoding, alongside peripherals including two Serial RapidIO links, a 1000 Mbps Ethernet MAC, and an antenna interface supporting OBSAI/CPRI standards.

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade suffix (e.g., -2 for 1.2 GHz) against the required operating frequency and temperature range. Confirm package availability as production status may vary. Ensure thermal management solutions are compatible with the SmartReflex adaptive voltage scaling requirements for proper device operation.

Digital Signal Processor Dsp Selection Notes

Select based on required clock frequency: 1.2 GHz for commercial temperatures (0°C to 95°C), 1 GHz for extended temperatures (-40°C to 100°C), or 850 MHz variants. Evaluate memory needs against the 3200 KB total on-chip capacity. Consider peripheral requirements such as the number of RapidIO links or EMAC channels needed for system connectivity.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320C6000 platform, representing a generation of high-performance multicore DSPs. It builds upon the C64x+ architecture, offering upward code compatibility with previous single-core devices while providing significantly increased throughput through parallel processing capabilities across multiple cores.

Digital Signal Processor Dsp Replacement Considerations

Direct pin-to-pin replacements within the same package are limited. Consider other C6474 speed grades (e.g., CUN, ZUN) if frequency or temperature ranges differ. For architectural upgrades, evaluate newer TI DSP families such as the C66x series for enhanced performance.
