TMS320C6474FZUNA2

Digital Signal Processor Dsp Overview

The TMS320C6474FZUNA2 is a multicore digital signal processor from Texas Instruments, featuring three independent C64x+ DSP cores. It operates at clock rates up to 1.2 GHz with an instruction cycle time of 0.83 ns. The device utilizes a 0.065-μm CMOS process and includes SmartReflex technology for adaptive voltage scaling between 0.9 V and 1.2 V. On-chip memory consists of 32 KB L1P cache, 32 KB L1D cache, and 64 KB L3 ROM per core, alongside a unified 3 MB L2 SRAM. Key peripherals include 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 ordering suffix 'FZUNA2' against official Texas Instruments documentation to confirm specific temperature range, speed grade, and packaging details. Ensure compliance with RoHS directives if required by the application environment. Confirm availability status as production data may vary over time.

Digital Signal Processor Dsp Selection Notes

Select this component for applications requiring high-performance multicore DSP processing with dedicated channel decoding capabilities. Consider the 561-pin BGA package constraints and thermal management requirements, as a heatsink is mandatory for operation within specified temperature ranges. Evaluate the need for SmartReflex implementation for optimal power efficiency.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320C64x+ family, which is part of the broader TMS320C6000 DSP platform. It represents a generation of high-performance multicore processors designed for complex signal processing tasks. The FZUNA2 suffix indicates a specific variant within the ZUN package family, distinguished by its pin count and physical dimensions compared to CUN or GUN variants.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements within the same package and pinout are limited. Upgrades may involve other C64x+ variants with different clock speeds or memory configurations. Cross-family migration to newer DSP generations requires significant architectural redesign.
