TNETV2665ZWT6

Overview

The TNETV2665ZWT6 is a digital signal processor from the TMS320C642x series, manufactured by Texas Instruments. It features a C64x+ fixed-point DSP core operating at clock rates up to 700MHz. The device integrates 240kB of on-chip RAM and 64kB of ROM. It utilizes a 361-NFBGA (16x16) package with a 0.5mm pitch. Electrical specifications include a core voltage of 1.05V or 1.20V and I/O voltages of 1.8V and 3.3V. The component supports an operating temperature range of 0°C to +90°C.

Feature Summary

• C64x+ fixed-point DSP architecture with processing speeds up to 700MHz
• Integrated memory comprising 240kB SRAM and 64kB boot ROM
• 361-pin NFBGA package suitable for high-density surface mount applications
• Dual voltage operation: 1.05V/1.20V core and 1.8V/3.3V I/O

Applications

• Digital media systems-on-chip implementations
• Video codec and image processing hardware
• Telecommunications baseband processing
• Industrial control systems requiring high-speed signal manipulation

Procurement Notes

Verify the specific suffix (e.g., WT6 vs WT7) against the datasheet to confirm speed grade and packaging configuration. Confirm moisture sensitivity level (MSL 3) requirements for storage and reflow soldering profiles. Ensure the ordering part number matches the exact pinout and thermal characteristics defined in the official Texas Instruments documentation.

Selection Notes

Select this component when a C64x+ DSP core is required for fixed-point arithmetic operations. Verify that the 361-NFBGA footprint fits the PCB layout constraints. Check if the 700MHz performance meets the throughput requirements compared to lower-speed variants like the TNETV2664. Ensure power supply designs accommodate the specified 1.05V/1.20V and 1.8V/3.3V rails.

Part Context

This part belongs to the Davinci Digital Media System family, integrating ARM cores alongside the C64x+ DSP. It is functionally related to the TMS320C6424 but includes additional peripherals for video and audio processing. The ZWT6 suffix indicates a specific commercial temperature range and tray packaging variant within the broader TNETV2665 product line.

Replacement Considerations

Direct substitutes include other TNETV2665 variants with different suffixes (e.g., TNETV2665FIDZWT7) which may differ only in speed binning or packaging quantity. Cross-referencing with the TMS320C6424 series is necessary for functional compatibility, though peripheral integration may vary.
