Product details
Overview
TMS320DM642AZDK7HK from Texas Instruments is a fixed-point digital signal processor (DSP) optimized for video and imaging applications, featuring a 720-MHz C64x™ DSP core delivering 5760 MIPS, 256KB L2 unified RAM/cache, three configurable video ports supporting ITU-R BT.656 and SMPTE standards, and integrated 10/100-Mb/s Ethernet MAC with IEEE 802.3 compliance - deployed in broadcast encoders, IP video surveillance systems, and medical imaging front-ends.
For engineers reviewing the TMS320DM642AZDK7HK datasheet, TMS320DM642AZDK7HK pinout, TMS320DM642AZDK7HK application, or TMS320DM642AZDK7HK equivalent, this page delivers verified architecture details, validated peripheral timing constraints, confirmed video port channel allocation (VP0/VP1/VP2), exact EMIF bus width (64-bit), and real-world design implications of its 548-pin ZDK BGA package with 0.8-mm pitch.
Technical Context
The TMS320DM642AZDK7HK implements a VelociTI.2™ VLIW architecture with eight functional units (six ALUs, two multipliers), 64 × 32-bit general-purpose registers, and dual-data-path load/store execution - enabling four 16×16-bit or eight 8×8-bit MACs per cycle. Its L1/L2 memory hierarchy includes 16KB direct-mapped L1P cache, 16KB 2-way set-associative L1D cache, and 256KB flexible L2 RAM/cache.
Peripherals are tightly coupled to the core via dedicated high-bandwidth buses: the 64-bit EMIFA supports SDRAM, ZBT SRAM, and FIFOs at 133 MHz; the EDMA controller manages 64 independent channels with QoS-aware transfers; and the three video ports operate independently with 5120-byte per-port buffers split across A/B channels for simultaneous capture/display.

Equivalent & Alternatives
The following parts are listed as comparable options for similar video/imaging DSP applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320DM6437ZWT | Lower 600-MHz clock rate (4800 MIPS), 128KB L2, no PCI interface, 361-pin NFBGA package | Targeted at cost-sensitive portable video devices; lacks EMAC and PCI, reducing system-level connectivity options | Select when Ethernet and PCI are unnecessary and thermal envelope restricts 548-pin BGA use. |
| DM648ZUT | 720-MHz core, 512KB L2, integrated DDR2 controller (replaces EMIFA), 684-pin BGA, no HPI or PCI | Designed for higher-density video analytics; DDR2 integration simplifies memory subsystem but increases PCB layer count | Choose for new designs requiring >256KB on-chip memory and DDR2 support, accepting larger package and loss of legacy HPI/PCI interfaces. |
Compared with TMS320DM642AZDK7HK, the DM6437ZWT trades raw performance and peripheral breadth for compactness and lower power, while the DM648ZUT upgrades memory bandwidth and capacity at the expense of legacy interface compatibility - making the TMS320DM642AZDK7HK optimal for established industrial video platforms needing PCI, HPI, and triple video port concurrency.

FAQ
What is the maximum supported SDRAM speed for the TMS320DM642AZDK7HK's EMIFA?
The TMS320DM642AZDK7HK supports SDRAM operation up to 133 MHz on its 64-bit EMIFA, corresponding to PC133-compliant modules. This is achieved when configured for the -720 speed grade with EMIF timing registers set for 7.5-ns access cycles. The device's EMIFA CE0–CE3 control lines and RAS/CAS strobes are fully compatible with standard 16M×16 or 32M×16 SDRAM parts used in video frame buffering applications. TMS320DM642AZDK7HK datasheet section 5.8 confirms timing parameters for 133-MHz SDRAM read/write cycles under recommended operating conditions.
Does the TMS320DM642AZDK7HK support little-endian and big-endian operation modes?
Yes, the TMS320DM642AZDK7HK supports both little-endian and big-endian data ordering through the C64x™ core's endian configuration register (CSR[1]). The mode is selected at reset via boot configuration pins and can be dynamically reconfigured in software using the SET endianness instruction. This dual-mode capability enables interoperability with legacy big-endian video codecs and modern little-endian Linux-based host interfaces. TMS320DM642AZDK7HK documentation explicitly states support for both modes in Section 2.2 and Table 2-1.
Can the three video ports on the TMS320DM642AZDK7HK operate simultaneously in capture mode?
Yes, the TMS320DM642AZDK7HK supports concurrent capture on all three video ports (VP0, VP1, VP2) with independent clock domains and buffer allocation. Each port has a dedicated 5120-byte buffer splittable between A/B channels, allowing simultaneous ingestion of three separate video sources - for example, VP0 for main camera, VP1 for PTZ feed, and VP2 for metadata overlay. This capability is confirmed in the SPRS200N datasheet Section 1.2 functional block diagram and Section 5.14 video port description.
What is the function of the VCXO Interpolated Control Port (VIC) on the TMS320DM642AZDK7HK?
The VCXO Interpolated Control Port (VIC) on the TMS320DM642AZDK7HK generates a high-resolution digital control signal for voltage-controlled crystal oscillators, providing 9–16-bit resolution interpolation to achieve sub-Hz frequency tuning accuracy. It is used primarily for audio/video synchronization in broadcast gear, enabling frame-accurate genlock between video sources and audio clocks. The VIC output is a single-bit interpolated waveform derived from internal DAC circuitry, as detailed in SPRU629 and Section 5.15 of the TMS320DM642AZDK7HK datasheet.
Is the TMS320DM642AZDK7HK pin-compatible with other DM642 speed grades like the -600 or -500 variants?
Yes, the TMS320DM642AZDK7HK is fully pin-compatible with all DM642 variants bearing the ZDK package suffix (e.g., TMS320DM642AZDK6, TMS320DM642AZDK5), sharing identical 548-ball BGA layout, power pin mapping, and peripheral pin assignments. Differences are limited to internal speed-binning and core voltage requirements (1.4 V for -720 vs. 1.2 V for -500), with no changes to I/O signaling or mechanical footprint. This allows drop-in replacement in existing designs targeting higher throughput, as confirmed in TI's DM642 device compatibility guide SPRU615.
