Product details
Overview
TMS320DM6467CZUTD7 from Texas Instruments is a dual-core digital media system-on-chip (SoC) integrating a 729-MHz TMS320C64x+ DSP and a 364.5-MHz ARM926EJ-S RISC processor, with 128KB L2 unified RAM/cache, dual HDVICP video co-processors, and 10/100/1000-Mb/s Ethernet MAC - deployed in networked video infrastructure and real-time H.264/MPEG4 encode/decode systems.
For engineers reviewing the TMS320DM6467CZUTD7 datasheet, TMS320DM6467CZUTD7 pinout, TMS320DM6467CZUTD7 application, or TMS320DM6467CZUTD7 equivalent, key selection criteria include DDR2 memory controller timing (310.5 MHz), VPIF video capture bandwidth (108 MHz), HDVICP hardware acceleration support for H.264/VC1, and industrial temperature grade (-40°C to 85°C) compliance.
Technical Context
The TMS320DM6467CZUTD7 implements a tightly coupled heterogeneous architecture: the ARM926EJ-S handles OS management, peripheral control, and high-level protocol stacks, while the C64x+ DSP executes real-time video algorithms at up to 5832 MIPS. Both cores share access to 128KB L2 memory with flexible RAM/cache allocation and coordinate via EDMA3 (64 channels) and shared interrupt controllers.
Hardware acceleration is distributed across dedicated subsystems: dual HDVICP engines perform parallel encode/decode of H.264, MPEG2, VC1, and MPEG4 SP/ASP; VDCE handles chroma conversion (4:2:2 ↔ 4:2:0) and downscaling; CRGEN modules enable precise clock recovery for TSIF transport stream inputs; and EMAC+MDIO provides full QoS-aware Gigabit Ethernet with automatic PHY enumeration.

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital media SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320DM6467CZUTD6 | Rated for 594-MHz DSP / 297-MHz ARM operation; lower DDR2 speed (297 MHz); -40°C to 85°C industrial grade | Suitable for cost-sensitive HD encode-only systems without dual HDVICP full-load concurrency | Select when thermal budget limits or lower video channel count reduces need for 729-MHz headroom |
| i.MX6Q | Quad-core ARM Cortex-A9 @ 1 GHz; no integrated DSP; GPU-based video acceleration (Vivante GC2000); lacks HDVICP-class codec hardware | Better for Android/Linux GUI-rich applications; weaker deterministic real-time video processing vs. C64x+ + HDVICP | Choose for UI-centric multimedia gateways where DSP offload is secondary to application CPU performance |
Compared with TMS320DM6467CZUTD7, the CZUTD6 offers identical packaging and industrial temp rating but trades 23% lower DSP throughput and reduced DDR2 bandwidth for lower power and cost; i.MX6Q provides higher general-purpose CPU performance and modern GPU acceleration but lacks the deterministic, low-latency video pipeline architecture and dual-HDVICP hardware essential for professional broadcast-grade encode/decode.

FAQ
What is the maximum DDR2 data rate supported by the TMS320DM6467CZUTD7?
The TMS320DM6467CZUTD7 supports a DDR2 memory controller operating at 310.5 MHz, enabling a peak theoretical bandwidth of 9.9 GB/s on its 32-bit bus. This rate is validated for industrial temperature range (-40°C to +85°C) operation and requires strict PCB layout adherence to TI's DDR2 routing guidelines, including length matching within ±10 mils and controlled impedance of 50 Ω ±5%.
Does the TMS320DM6467CZUTD7 include hardware support for H.264 High Profile decoding?
Yes, the TMS320DM6467CZUTD7 integrates two independent HDVICP (High-Definition Video/Imaging Co-Processor) engines that natively support H.264 High Profile decoding and encoding, along with MPEG2, VC1, and MPEG4 SP/ASP. These accelerators operate in parallel with the C64x+ DSP core, allowing full-resolution 1080p60 decode without consuming DSP MIPS - confirmed in TI's SPRS403H datasheet Section 1.1 and DVSDK 3.x documentation.
What is the function of the CRGEN modules in the TMS320DM6467CZUTD7?
The TMS320DM6467CZUTD7 includes two Clock Recovery Generator (CRGEN) modules, each paired with a TSIF transport stream interface. These modules recover precise bit-clock and byte-clock timing from asynchronous MPEG-TS serial streams using an external VCXO, enabling jitter-free demultiplexing without requiring external clock recovery ICs - a key feature for broadcast-grade IPTV and DVB-ASI receiver designs.
Can the TMS320DM6467CZUTD7 operate in both little-endian and big-endian modes?
No, the TMS320DM6467CZUTD7 operates exclusively in little-endian mode for both the ARM926EJ-S and C64x+ DSP cores, as explicitly stated in Section 1.1 of the SPRS403H datasheet. Endianness is hardwired and not software-configurable; all memory-mapped peripherals, L1/L2 caches, and DMA transfers assume little-endian byte ordering.
What boot sources are supported by the TMS320DM6467CZUTD7's on-chip ROM bootloader?
The TMS320DM6467CZUTD7's on-chip ARM ROM bootloader (RBL) supports boot from NAND flash, NOR flash, UART, and EMIFA-connected peripherals - as documented in Section 4.4 of SPRS403H. It does not support direct boot from DDR2 or USB; those require secondary-stage loaders. Boot mode is selected via strap pins (BOOTCFG[3:0]) at reset, with NAND boot being most common for field-upgradable video systems.
