Texas Instruments TMS320DM6467TZUT1

Overview

TMS320DM6467TZUT1 from Texas Instruments is a dual-core digital media system-on-chip (SoC) integrating a 1-GHz TMS320C64x+ DSP core and a 500-MHz ARM926EJ-S RISC processor, with 128KB L2 unified RAM/cache, dual HDVICP video co-processors, and 150-MHz configurable video port interface (VPIF). It targets real-time H.264/MPEG-4/VC-1 encode/decode in networked media infrastructure.

For engineers reviewing the TMS320DM6467TZUT1 datasheet, TMS320DM6467TZUT1 pinout, TMS320DM6467TZUT1 application, or TMS320DM6467TZUT1 equivalent, key selection criteria include DDR2 memory controller timing (400 MHz), dual HDVICP hardware acceleration support, VPIF BT.656/BT.1120 interface capability, and industrial-grade 529-pin CUT BGA packaging.

Technical Context

The TMS320DM6467TZUT1 implements a tightly coupled heterogeneous architecture: the ARM926EJ-S handles OS services, peripheral control, and system boot via on-chip 8KB ROM bootloader, while the C64x+ DSP executes compute-intensive video algorithms at 8000 MIPS. Both cores share access to 128KB L2 memory configured as flexible RAM/cache.

Hardware acceleration is distributed across dedicated blocks: dual HDVICP engines offload H.264 Baseline/Main Profile and MPEG-4 SP/ASP encoding/decoding; VDCE performs chroma conversion (4:2:2 ↔ 4:2:0) and horizontal/vertical downscaling; TSIF modules with CRGEN support MPEG transport stream time-stamp recovery and PID filtering.

FAQ

What is the maximum DDR2 data rate supported by the TMS320DM6467TZUT1?

The TMS320DM6467TZUT1 supports a DDR2 memory controller operating at up to 400 MHz (200 MHz clock with double-data-rate), delivering 3.2 GB/s peak bandwidth on its 32-bit bus. This enables real-time buffering of multiple HD video streams in applications such as multi-channel NVRs. The controller complies with JEDEC DDR2 specifications and supports programmable timing parameters including tRCD, tRP, and tRAS.

Does the TMS320DM6467TZUT1 support H.264 encode functionality?

Yes, the TMS320DM6467TZUT1 supports full H.264 Baseline and Main Profile encode via its dual HDVICP engines. Each HDVICP can independently handle encode or decode operations, allowing simultaneous encode of one stream and decode of another. The SoC's 1-GHz C64x+ DSP core provides additional headroom for pre-processing (e.g., noise reduction) and post-processing (e.g., bitstream formatting) tasks not handled by HDVICP.

What video interface standards does the TMS320DM6467TZUT1 VPIF support?

The TMS320DM6467TZUT1 VPIF supports BT.656 (8-bit SD), BT.1120 (16-bit HD), and raw video formats (8-/10-/12-bit) across two independent capture and two display channels. It operates at up to 150 MHz, enabling 1080p60 capture or display when configured in HD mode. The interface includes built-in sync detection, EAV/SAV parsing, and programmable pixel clock dividers for flexible sensor/display timing alignment.

Is the TMS320DM6467TZUT1 pin-compatible with other DaVinci devices like the DM6446?

No, the TMS320DM6467TZUT1 is not pin-compatible with the DM6446 or other DaVinci predecessors. It uses a unique 529-pin CUT BGA footprint with distinct power domain assignments (e.g., separate VDD_IO_18 and VDD_IO_33 rails), different clock input requirements (DEV_CLKIN + AUX_CLKIN), and expanded peripheral pinouts (e.g., dual TSIF, VLYNQ, PCI). Migration requires PCB redesign and signal integrity revalidation.

What boot options are available for the TMS320DM6467TZUT1?

The TMS320DM6467TZUT1 supports multiple boot modes controlled by strapping pins: NAND flash, NOR flash, UART, USB, and EMIFA. Its on-chip 8KB ARM ROM contains a bootloader (RBL) that initializes clocks, configures PLLs, and loads the second-stage bootloader from the selected medium. The RBL supports secure boot via hash verification when paired with external authentication hardware.
