Product details
Overview
TNETV2667FIBZWT from Texas Instruments is a fixed-point digital signal processor (DSP) based on the C64x+™ VLIW architecture, delivering up to 5600 MIPS at 700 MHz with 32 KB L1P program RAM/cache, 80 KB L1D data RAM/cache, and 128 KB unified L2 RAM/cache. It integrates a 32-bit DDR2 SDRAM memory controller, dual McBSPs, McASP0 with four serializers, EMAC with MDIO, and supports telecom, audio, and industrial real-time signal processing.
For engineers reviewing the TNETV2667FIBZWT datasheet, TNETV2667FIBZWT pinout, TNETV2667FIBZWT application, or TNETV2667FIBZWT equivalent, key selection considerations include its 361-pin ZWT PBGA package, 1.2-V core / 1.8-V I/O voltage configuration, 700-MHz clock rate, integrated boot ROM, and support for IEEE 802.3-compliant 10/100 Mb/s Ethernet connectivity.
Technical Context
The TNETV2667FIBZWT implements the C64x+™ DSP core with eight functional units (six ALUs, two multipliers), 64 × 32-bit general-purpose registers, and VelociTI.2™ instruction set enhancements including complex multiply, bit-field extract/set/clear, and compact 16-bit instructions. It features protected mode operation, hardware modulo loop support, and exception handling for robust real-time execution.
Its memory subsystem includes flexible L1P/L1D allocation (cache or mapped RAM), unified L2 with configurable cache/mapped modes, and dual external memory interfaces: a 32-bit DDR2 SDRAM controller (256 MB address space) and a 16-bit asynchronous EMIFA (128 MB). Peripherals include EDMA3 with 64 channels, two 64-bit timers, three PWM outputs, and PCI 33-MHz master/slave interface.

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-point DSP applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320C6422ZWT | Lower clock grade (500 MHz max), reduced L2 (64 KB), no EMAC or PCI; same ZWT package and pinout | Suitable for cost-sensitive audio or telecom edge nodes where Ethernet and PCI are unnecessary | Select when system bandwidth and peripheral count are lower, and 4000 MIPS suffices for target workload |
| TMS320C6455ZTZ | Higher-performance variant (1 GHz), larger L2 (2 MB), enhanced EMAC (with RGMII), but 529-pin ZTZ package (not pin-compatible) | Targeted at high-end baseband processing and radar signal conditioning requiring >8000 MIPS | Choose only if migrating to higher compute density and can accommodate larger PCB footprint and thermal design |
Compared with TNETV2667FIBZWT, the C6422ZWT offers identical packaging and software compatibility at lower cost and power, while the C6455ZTZ delivers significantly higher throughput and memory bandwidth at the expense of board redesign and increased power delivery complexity.

FAQ
What is the maximum operating frequency of the TNETV2667FIBZWT?
The TNETV2667FIBZWT operates at a maximum clock rate of 700 MHz, achieving 5600 million instructions per second (MIPS) with a 1.2-V core supply. At 1.05-V core voltage, it supports up to 560 MHz for low-power configurations. This frequency is confirmed in the SPRS347D datasheet Section 2.1, Table 2-1, under CPU Frequency specifications for the -7 speed grade.
Does the TNETV2667FIBZWT support DDR2 memory, and what are its interface capabilities?
Yes, the TNETV2667FIBZWT integrates a 32-bit DDR2 SDRAM memory controller supporting data rates up to 333 MHz (DDR2-400), 256 MB address space, and standard DDR2 command protocols. It includes dedicated DQS strobes, on-die termination control, and programmable timing parameters for reliable high-speed memory access - detailed in Section 6.9 of the SPRS347D datasheet.
What boot options are supported by the TNETV2667FIBZWT?
The TNETV2667FIBZWT includes an on-chip ROM bootloader that supports boot from NAND flash, NOR flash, EMAC (network boot), UART, or HPI interfaces. Boot mode is selected via GPIO strap pins at reset. No external boot PROM is required, simplifying system initialization - described in Section 3.4 "Boot Sequence" of the SPRS347D datasheet.
Is the TNETV2667FIBZWT pin-compatible with other C642x family members?
The TNETV2667FIBZWT uses the 361-pin ZWT PBGA package and shares identical pinout with other C642x devices in the same package variant (e.g., TMS320C6422ZWT, TMS320C6424ZWT). Signal mapping, power pin locations, and ball pitch are fully consistent, enabling drop-in replacement within the ZWT footprint - verified in Section 2.4 "Pin Assignments" of SPRS347D.
What development tools are available for the TNETV2667FIBZWT?
Texas Instruments provides a complete toolchain for the TNETV2667FIBZWT, including Code Generation Tools (C/C++ compiler, assembler, linker), Code Composer Studio™ IDE (v3.3+), DSP/BIOS real-time kernel, and C64x+ Cycle Accurate Simulator.
