Texas Instruments TMS320C6472EZTZ7

Overview

TMS320C6472EZTZ7 from Texas Instruments is a fixed-point digital signal processor (DSP) with six independent C64x+ megamodules operating at 700 MHz, delivering 5600 MIPS/44800 MMACs (16-bit), 768 KB shared L2 SRAM, dual IEEE 802.3-compliant 10/100/1000 Mb/s Ethernet MACs, and a 32-bit DDR2-533 memory controller - deployed in high-end telecom infrastructure, media gateways, and remote access servers.

For engineers reviewing the TMS320C6472EZTZ7 datasheet, TMS320C6472EZTZ7 pinout, TMS320C6472EZTZ7 application, or TMS320C6472EZTZ7 equivalent, key selection criteria include multi-core deterministic real-time processing capability, on-chip memory hierarchy (32 KB L1P/L1D per core + 608 KB local L2 + 768 KB shared SL2), UTOPIA Level 2 slave ATM interface, Serial RapidIO v1.2 support, and 737-pin CTZ/ZTZ BGA package compatibility.

Technical Context

The TMS320C6472EZTZ7 implements six fully independent C64x+ DSP megamodules, each with an eight-functional-unit VLIW core, dual 32-bit register files, and dedicated L1P/L1D memory controllers. Each megamodule executes eight 16-bit × 16-bit MACs per cycle and supports SPLOOP for software-pipelined loop acceleration.

System-level interconnect includes a switched central resource (SCR) fabric enabling coherent access to shared peripherals: dual EMACs sharing one MDIO interface, three TSIP ports, I2C, HPI16, and a unified 768 KB SL2 RAM accessible by all cores. Clocking uses three independent PLLs - PLL1 for system clock, PLL2 for EMAC, and PLL3 for DDR2 - ensuring domain-specific frequency optimization.
