Product details
Overview
TMS320DM642AZNZ5 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 memory/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 and IP-based video surveillance systems.
For engineers reviewing the TMS320DM642AZNZ5 datasheet, TMS320DM642AZNZ5 pinout, TMS320DM642AZNZ5 application, or TMS320DM642AZNZ5 equivalent, key selection criteria include its 548-pin BGA (ZNZ suffix, 1.0-mm ball pitch), 3.3-V I/O / 1.4-V core voltage, VelociTI.2™ VLIW architecture with eight functional units, EDMA controller with 64 independent channels, and McASP0 supporting S/PDIF and AES-3 audio encoding.
Technical Context
The TMS320DM642AZNZ5 implements a two-level cache hierarchy: 16KB direct-mapped L1P program cache and 16KB 2-way set-associative L1D data cache, backed by 256KB flexible L2 unified memory/cache that supports dynamic allocation between RAM and cache modes. Its C64x™ core executes up to eight 32-bit instructions per cycle using VelociTI.2™ extensions including quad 8-bit and dual 16-bit arithmetic, saturation, normalization, and bit-field manipulation.
Peripheral integration includes three multiplexed video ports (VP0–VP2) supporting simultaneous capture/display with 5120-byte channel buffers, a 64-bit EMIFA interfacing to SDRAM/ZBT SRAM/FIFO, PCI 2.2-compliant 32-bit/66-MHz master/slave interface, and McASP0 with eight serial data pins capable of concurrent 192-kHz stereo transmission and multi-channel S/PDIF output from a single RAM buffer.

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 memory, same 548-pin ZWT package but 0.8-mm pitch; lacks PCI interface. | Targeted at cost-sensitive portable video devices; insufficient L2 for multi-stream 1080p encode. | Select only when thermal/power budget prohibits 720-MHz operation and PCI connectivity is unnecessary. |
| OMAP-L138 | ARM9 + C674x DSP dual-core; 375-MHz DSP (3000 MIPS), 128KB L2, integrated DDR2 controller; different architecture and toolchain. | Designed for Linux-based multimedia gateways requiring OS services; not pin-compatible or code-compatible with DM642. | Choose for applications needing rich OS support and mixed ARM/DSP workload partitioning - not for drop-in replacement. |
Compared with TMS320DM642AZNZ5, the TMS320DM6437ZWT trades peak performance and L2 capacity for lower power, while OMAP-L138 shifts from pure DSP-centric design to heterogeneous SoC architecture - making TMS320DM642AZNZ5 uniquely suited for legacy C64x-based video infrastructure requiring maximum deterministic throughput.

FAQ
What is the core voltage requirement for the TMS320DM642AZNZ5?
The TMS320DM642AZNZ5 requires a 1.4-V core supply (VDD_CORE) for operation at its rated 720-MHz clock speed. This voltage is specified for the A-720 variant denoted by the "-720" suffix in the part number. Deviation outside ±3% tolerance may cause timing violations or functional failure during sustained video processing loads.
Does the TMS320DM642AZNZ5 support PCIe interface?
No, the TMS320DM642AZNZ5 does not support PCIe. It features a PCI 2.2-compliant 32-bit/66-MHz master/slave interface, which is electrically and protocol-wise incompatible with PCIe. Systems requiring PCIe must use an external bridge IC or select a newer-generation SoC.
Can the TMS320DM642AZNZ5 directly drive an HDMI transmitter?
The TMS320DM642AZNZ5 cannot directly drive HDMI; it lacks TMDS physical layer circuitry. However, its VP0/VP1/VP2 ports provide glueless parallel interface to HDMI receiver/transmitter ICs compliant with BT.656 or custom RGB/YUV formats - requiring external HDMI PHY such as TI TFP410 or Parade PS8315.
What video standards are supported by the TMS320DM642AZNZ5 video ports?
The TMS320DM642AZNZ5 video ports natively support CCIR-601, ITU-R BT.656, BT.1120, SMPTE 125M, 260M, 274M, and 296M standards. These are implemented in hardware within the VP peripherals and require no firmware decoding - enabling real-time capture/display of interlaced and progressive video formats up to 1080i60.
Is the TMS320DM642AZNZ5 RoHS compliant?
Yes, the TMS320DM642AZNZ5 is RoHS compliant and lead-free, as confirmed by Texas Instruments' official product change notices and material declarations dated October 2010. The ZNZ package uses matte tin finish on solder balls and complies with JEDEC J-STD-020 moisture sensitivity level 3.
