Product details
Overview
TMS320DM6443BZWT from Texas Instruments is a dual-core digital media system-on-chip integrating a 594-MHz C64x+ DSP and a 297-MHz ARM926EJ-S RISC processor in a single 361-pin Pb-free BGA (ZWT) package. It delivers 4752 MIPS DSP performance and includes integrated video processing subsystem (VPSS) with resizer, on-screen display (OSD), and analog/digital video encoder for NTSC/PAL/S-Video/RGB output. It targets embedded networked media encode/decode applications such as IP cameras and portable media players.
For engineers reviewing the TMS320DM6443BZWT datasheet, TMS320DM6443BZWT pinout, TMS320DM6443BZWT application, or TMS320DM6443BZWT equivalent, key selection criteria include dual-core clock domain coordination, DDR2 + EMIFA memory interface support, VPBE analog DAC timing compliance, EDMA3 channel allocation, and ARM/DSP co-boot sequencing via ROM bootloader.
Technical Context
The TMS320DM6443BZWT implements a tightly coupled dual-processor architecture where the ARM926EJ-S handles OS services, user interface, and peripheral control while the C64x+ DSP executes real-time video encoding/decoding algorithms. The Switched Central Resource (SCR) interconnect manages arbitration between ARM, DSP, EDMA3, and peripherals using configurable bus master priorities.
Its Video Processing Subsystem (VPSS) comprises a front-end resizer supporting 1/4× to 4× scaling with separate horizontal/vertical control and a back-end (VPBE) with four 10-bit DACs operating at 54 MHz for composite/YPbPr output plus 8-/16-/24-bit digital BT.656/CCIR.601 RGB interfaces. The VPBE operates synchronously with VPBECLK, not PCLK, per silicon revision 2.3 updates.

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital media SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320DM6446BZWT | Includes VPFE (video front-end) for CCD/CMOS sensor input; adds 10/100 EMAC with MDIO polling; same ZWT package | Required for camera systems needing raw sensor capture; DM6443 lacks VPFE and only supports video decode/display | Select DM6446 when sensor interface is needed; DM6443 suffices for playback-only or encoded-input use cases |
| OMAP-L138BZWT | ARM9 + C674x floating-point DSP; lower 375-MHz DSP clock; no integrated VPBE DACs; supports uPP interface | Better suited for floating-point audio processing or radar; requires external video encoder for analog output | Choose OMAP-L138 for mixed-signal control + floating-point math; retain DM6443 for cost-sensitive analog video output |
Compared with TMS320DM6446BZWT, the TMS320DM6443BZWT omits VPFE but reduces cost and power for playback-centric designs; versus OMAP-L138BZWT, it provides integrated analog video output and higher fixed-point DSP throughput at the expense of floating-point capability.

FAQ
What is the maximum supported DDR2 memory size for the TMS320DM6443BZWT?
The TMS320DM6443BZWT DDR2 memory controller supports up to 256 MB of address space with a 32-bit data bus. This capacity accommodates multiple high-resolution video frame buffers and codec working memory required for real-time H.264 encode/decode operations. The TMS320DM6443BZWT does not support DDR3 or LPDDR variants.
Does the TMS320DM6443BZWT support booting from NAND flash?
Yes, the TMS320DM6443BZWT includes an on-chip ARM ROM Bootloader (RBL) that supports direct boot from NAND flash devices connected to the EMIFA. The RBL validates image integrity and loads both ARM and DSP firmware without requiring external boot ROM or host intervention.
What video output standards does the TMS320DM6443BZWT VPBE support?
The TMS320DM6443BZWT VPBE supports NTSC and PAL composite video via its four 10-bit DACs, S-Video (Y/C), and component video (YPbPr or RGB) up to 720p progressive scan. Digital output includes 8-/16-bit BT.656 and 24-bit RGB888 with separate HSYNC/VSYNC signals.
How many independent EDMA3 channels does the TMS320DM6443BZWT provide?
The TMS320DM6443BZWT integrates an EDMA3 controller with 64 independent DMA channels and 8 QDMA channels. This allows concurrent data movement between DDR2, L2 memory, peripherals (EMAC, USB, VPBE), and DSP/ARM address spaces without CPU intervention.
Is the TMS320DM6443BZWT pin-compatible with other DaVinci devices like the DM6441 or DM6446?
No, the TMS320DM6443BZWT is not pin-compatible with DM6441 or DM6446. While all share the ZWT BGA package, pin functions differ significantly - e.g., DM6446 includes VPFE signals absent on DM6443, and DM6441 lacks VPBE DAC outputs. PCB layout must be specific to TMS320DM6443BZWT.
