Texas Instruments TMS320DM647CUT9

Overview

TMS320DM647CUT9 from Texas Instruments is a fixed-point digital media processor based on the C64x+™ DSP core, operating at 900 MHz with 256 KB L2 unified RAM/cache, five configurable video ports, and integrated 3-port Gigabit Ethernet switch subsystem. It targets real-time video encoding/decoding in embedded DVRs, IP cameras, and broadcast infrastructure where deterministic low-latency processing and multi-standard video I/O are required.

For engineers reviewing the TMS320DM647CUT9 datasheet, TMS320DM647CUT9 pinout, TMS320DM647CUT9 application, or TMS320DM647CUT9 equivalent, key selection criteria include its 900-MHz C64x+ core performance (7200 MIPS), DDR2 + EMIFA dual-memory interface, SGMII Ethernet port, VCXO-interpolated timing control, and 529-pin nFBGA (ZUT) package compatibility with industrial temperature operation.

Technical Context

The TMS320DM647CUT9 implements a two-level cache hierarchy: 32 KB L1P direct-mapped program cache and 32 KB L1D 2-way set-associative data cache, backed by 256 KB L2 unified RAM/cache configurable as memory, cache, or hybrid. Its C64x+ core delivers eight functional units-including two multipliers enabling four 16×16-bit MACs/cycle-and supports little-endian mode only.

Peripheral integration includes a 32-bit DDR2 SDRAM controller (1.8-V I/O, 512 MB address space), asynchronous 16-bit EMIFA supporting SRAM/Flash/ZBT, five 16-bit video ports compliant with ITU-BT.656, SMPTE 274M, and CCIR601, plus a single SGMII port for 1-Gbps Ethernet connectivity and VIC for audio/video synchronization.

FAQ

What is the maximum operating frequency of the TMS320DM647CUT9?

The TMS320DM647CUT9 operates at a guaranteed maximum frequency of 900 MHz, delivering 7200 million instructions per second (MIPS). This corresponds to a 1.11 ns instruction cycle time and is validated across the industrial temperature range (–40°C to 85°C). The device also supports 720-MHz and 1100-MHz speed grades, but TMS320DM647CUT9 is specifically rated and tested for 900-MHz operation.

Does the TMS320DM647CUT9 support DDR2 memory, and what are its interface specifications?

Yes, the TMS320DM647CUT9 integrates a 32-bit DDR2 SDRAM memory controller supporting 1.8-V I/O and up to 512 MB of address space. It complies with JEDEC DDR2 standards, supports programmable CAS latency, burst lengths of 4 or 8, and auto-precharge. The controller includes dedicated command/address and data strobe routing requirements, and requires board-level termination matching DDR2 specifications.

How many video ports does the TMS320DM647CUT9 have, and what video standards do they support?

The TMS320DM647CUT9 features five independent 16-bit configurable video ports (VP0–VP4), each supporting both capture and display modes. These ports implement glueless interfaces to common video encoders/decoders and support ITU-R BT.656, BT.1120, SMPTE 274M (1080p), SMPTE 296M (720p), CCIR601, and SMPTE 125M/260M standards with embedded sync and field identification.

What Ethernet capabilities are integrated into the TMS320DM647CUT9?

The TMS320DM647CUT9 includes a fully integrated 3-port Gigabit Ethernet switch subsystem with one SGMII port (1.25 Gbps), MDIO management interface, and hardware-accelerated forwarding logic. It supports IEEE 802.3, VLAN tagging, and priority-based queuing-enabling standalone networked video streaming without external PHY or switch ICs.

Is the TMS320DM647CUT9 pin-compatible with other devices in the DM64x family?

The TMS320DM647CUT9 shares the same 529-pin nFBGA (ZUT) package and pinout with the TMS320DM648CUT9, enabling mechanical compatibility and PCB reuse. However, functional differences-including L2 size, SGMII count, and temperature grade options-require firmware and layout validation. It is not pin-compatible with earlier DM642 or DM643 devices due to differing peripheral sets and memory interface configurations.
