Product details
Overview
TNETV2666INZWT 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 controller, dual McBSPs, McASP0 with four serializers, EMAC with MDIO, and supports telecom, audio, and industrial real-time signal processing.
For engineers reviewing the TNETV2666INZWT datasheet, TNETV2666INZWT pinout, TNETV2666INZWT application, or TNETV2666INZWT equivalent, this page provides verified technical context, package mapping to the 361-pin ZWT PBGA, confirmed pin functions, key timing and memory parameters, and two validated alternative DSPs for fixed-point high-throughput embedded signal processing.
Technical Context
The TNETV2666INZWT implements the C64x+™ DSP core with eight functional units (six ALUs, two multipliers), 64 × 32-bit general-purpose registers, and VelociTI.2™ VLIW extensions enabling four 16×16-bit MACs/cycle (2800 MMACS) or eight 8×8-bit MACs/cycle (5600 MMACS). Its memory subsystem includes flexible L1P/L1D allocation and unified L2 cache/RAM with configurable writeback/invalidate policies.
Peripheral integration includes a 10/100-Mb/s IEEE 802.3-compliant EMAC with MII/RMII support, asynchronous 16-bit EMIFA for NOR/NAND flash, dual UARTs (one with RTS/CTS), I²C master/slave, three PWM outputs, and 111 GPIO pins multiplexed with peripheral functions - all managed via a centralized interrupt controller and EDMA3 with 64 independent channels.
Key Specifications

| VLYNQ Interface | 4-bit transmit/receive FPGA interconnect enables glueless expansion of I/O or custom logic without external bus buffers. |
| ROM Bootloader | 64 KB on-chip boot ROM supports secure image validation, encrypted loading, and fallback recovery from corrupted external media. |
| Power Management | Multiple low-power modes (IDLE, STANDBY, DEEPSLEEP) with individual peripheral clock gating reduce active power to sub-100 mW in idle states. |
