Product details
Overview
DM3730CUS from Texas Instruments is a high-performance digital media processor integrating an ARM Cortex-A8 microprocessor core (up to 1 GHz), a TMS320C64x+ DSP core (up to 800 MHz), and a POWERVR SGX graphics accelerator - all on a single 45-nm CMOS die. It delivers concurrent video decode/encode (H.264, MPEG-4), 2D/3D graphics rendering, and real-time audio processing for portable infotainment and industrial HMI systems.
For engineers reviewing the DM3730CUS datasheet, DM3730CUS pinout, DM3730CUS application, or DM3730CUS equivalent, this page provides verified package mapping (423-pin s-PBGA, CUS suffix), validated IVA2.2 subsystem capabilities, confirmed SmartReflex™ DVFS support, and precise GPIO multiplexing context for embedded Linux and Windows CE design integration.
Technical Context
The DM3730CUS implements a heterogeneous dual-core architecture: the ARM Cortex-A8 executes HLOS tasks with TrustZone security and NEON SIMD acceleration, while the C64x+ DSP handles computationally intensive media pipelines including codec offload and image signal processing. Both cores share a unified L3 interconnect and access to 256 KB L2 cache.
Its IVA2.2 subsystem integrates dedicated hardware accelerators for video (MPEG-4/H.264 encode/decode), imaging (ISP with BT.601/BT.656 interface), and graphics (POWERVR SGX delivering up to 20 MPoly/sec). The device supports parallel SDRAM via SDRC and glueless NAND/NOR/SRAM interfacing through GPMC - critical for boot reliability and memory bandwidth in multimedia edge devices.

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital media processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DM3730CBP | 515-pin s-PBGA, 0.5-mm (top)/0.4-mm (bottom) ball pitch; supports POP memory stacking; includes additional GPIOs and McBSP channels. | Targeted at higher-bandwidth designs requiring stacked LPDDR and >180 GPIOs - unsuitable for space-constrained CUS footprint. | Select DM3730CBP only when POP memory integration or expanded peripheral count is mandatory; not drop-in compatible with CUS layout. |
| AM3715CUS | Same 423-pin CUS package and pinout; identical ARM/DSP cores but omits POWERVR SGX graphics accelerator and reduces IVA2.2 video capability. | Used where graphics rendering is unnecessary (e.g., headless industrial gateways); lower thermal envelope and BOM cost. | AM3715CUS is pin-compatible and software-compatible for non-graphics use cases - ideal for cost-sensitive, non-UI applications. |
Compared with DM3730CBP and AM3715CUS, the DM3730CUS uniquely balances full multimedia acceleration (SGX + IVA2.2) within a compact 423-ball footprint - making it optimal for space-constrained, graphics-intensive embedded displays where POP memory is not required.

FAQ
What is the maximum operating frequency of the ARM Cortex-A8 core in the DM3730CUS?
The DM3730CUS ARM Cortex-A8 core operates at up to 1 GHz under OPP100 conditions. It also supports lower OPPs (OPP80 at 800 MHz, OPP50 at 500 MHz) with corresponding voltage scaling via SmartReflex AVS to optimize power efficiency for varying workload demands.
Does the DM3730CUS include a graphics processing unit, and what APIs does it support?
Yes, the DM3730CUS integrates a POWERVR SGX graphics accelerator supporting OpenGL ES 1.1 and 2.0, as well as OpenVG 1.0. This enables hardware-accelerated 2D/3D graphics rendering, UI composition, and video overlay - confirmed in TI SPRS685D Section 1.1 and Figure 1-1.
Is the DM3730CUS pin-compatible with the AM3715CUS?
Yes, the DM3730CUS and AM3715CUS share identical 423-pin s-PBGA (CUS) packaging, mechanical footprint, and ball map. They are pin-compatible for PCB layout, though software must account for missing SGX and reduced IVA2.2 features in the AM3715CUS.
What memory interfaces does the DM3730CUS support for external storage?
The DM3730CUS supports SDRAM via its SDRC (16-/32-bit, 1-GByte space) and NAND/NOR/SRAM/OneNAND via its GPMC (8 chip selects, 128-MByte per CS). It also includes three MMC/SDIO controllers - one supporting eMMC 4.41 with built-in ECC for reliable boot storage.
What video input standards does the DM3730CUS camera interface support?
The DM3730CUS camera interface supports BT.601 and BT.656 digital YCbCr 4:2:2 formats at 8- and 10-bit depth, with parallel CCD/CMOS imager connectivity via cam_pclk, cam_hs, cam_vs, and 12-bit data lines - fully documented in Section 2.2.1 and Table 2-25 of SPRS685D.
