TMS320C6474FGUN

Digital Signal Processor Dsp Overview

The TMS320C6474FGUN is a multicore digital signal processor from Texas Instruments, featuring three independent C64x+ DSP cores. It utilizes a 0.065-μm CMOS process and operates at clock rates up to 1.2 GHz with an instruction cycle time of 0.83 ns. The device integrates 32 KB L1P program cache, 32 KB L1D data cache, and 64 KB L3 ROM per core, alongside a 3-MB unified L2 SRAM. Key peripherals include two Serial RapidIO links, a 1000 Mbps Ethernet MAC, six antenna interface links, and dedicated VCP2/TCP2 decoders. It is housed in a 561-pin FBGA package (27x27 mm) with a 0.8-mm ball pitch.

• Telecommunications base stations

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade suffix (e.g., -2 for 1.2 GHz, -1 for 1 GHz, or -8 for 850 MHz) against project requirements. Confirm temperature range compliance, as the FGUN suffix typically denotes commercial or extended temperature variants depending on the full part number construction. Ensure heatsink implementation is planned for thermal management given the SmartReflex voltage regulation requirements.

Digital Signal Processor Dsp Selection Notes

Select based on required clock frequency: 1.2 GHz for maximum throughput, 1 GHz for standard performance, or 850 MHz for lower power applications. Verify memory configuration needs; the device provides 3 MB of L2 SRAM shared across cores. Check peripheral availability, noting that not all pins are accessible simultaneously due to pin multiplexing constraints defined in the datasheet.

Digital Signal Processor Dsp Part Context

The TMS320C6474 belongs to the C6000 multicore DSP platform, succeeding single-core C64x devices. It represents a shift toward parallel processing for high-throughput applications. The 'FGUN' designation indicates the 561-pin BGA package type, while the numeric suffix defines the operational frequency and temperature rating.

Digital Signal Processor Dsp Replacement Considerations

Direct pin-to-pin replacements within the same package are limited. Consider the TMS320C6472 for similar functionality at lower speeds or the TMS320C667x series for newer architectures, though software migration may be required.
