For engineers reviewing the DM3730CUSD100 datasheet, DM3730CUSD100 pinout, DM3730CUSD100 application, or DM3730CUSD100 equivalent, key selection criteria include its 45-nm process, dual-core heterogeneous architecture, integrated SGX GPU, SmartReflex dynamic voltage/frequency scaling, and support for Linux and Windows Embedded CE operating systems.

Technical Context

The DM3730CUSD100 implements a hierarchical L3/L4 interconnect fabric linking its ARM Cortex-A8 MPU subsystem, C64x+ DSP subsystem, POWERVR SGX graphics engine, and IVA2.2 hardware accelerators. Its memory subsystem includes 256KB L2 cache, 64KB on-chip RAM, and dedicated SDRAM controller with SMS rotation engine.

It features dual-domain power management with SmartReflex AVS enabling adaptive core voltages (0.9–1.2 V) and I/O voltages (1.8 V), alongside comprehensive clock domain control via multiple DPLLs and DLLs for precise timing across MPU, DSP, graphics, and peripheral interfaces.

Key Specifications

Pinout & Package

The DM3730CUSD100 is packaged in a 423-ball s-PBGA (CUS package) with 0.65mm ball pitch. Top-side balls are omitted per TI documentation; all signals are assigned to bottom-side pads. Pin functions are highly multiplexed across 188 GPIOs and dedicated peripheral interfaces.

FAQ

What is the maximum operating frequency of the ARM Cortex-A8 core in the DM3730CUSD100?

The DM3730CUSD100 supports an ARM Cortex-A8 core operating at up to 1 GHz under commercial temperature conditions. It also supports lower OPPs at 300 MHz, 600 MHz, and 800 MHz for power-optimized configurations. The actual achievable frequency depends on thermal design and SmartReflex voltage calibration, but the DM3730CUSD100 datasheet specifies 1 GHz as the maximum rated performance point for this CUS-package variant.

Does the DM3730CUSD100 include a POWERVR graphics accelerator?

Yes, the DM3730CUSD100 integrates a POWERVR SGX530 graphics accelerator delivering up to 20 MPoly/sec. This GPU supports OpenGLES 1.1 and 2.0, OpenVG 1.0, and features a universal scalable shader engine for pixel and vertex processing. Unlike the DM3725, the DM3730CUSD100 includes this graphics block-making it essential for UI-rich applications requiring hardware-accelerated rendering.

What memory interfaces are supported by the DM3730CUSD100?

The DM3730CUSD100 supports two primary memory interfaces: a SDRAM Controller (SDRC) for DDR2 and LPDDR memory, and a General Purpose Memory Controller (GPMC) for NOR/NAND flash, SRAM, and FPGA interfacing. The SDRC includes a memory scheduler and rotation engine, while the GPMC provides up to 8 chip selects with 128MB address space each and built-in Hamming ECC for NAND reliability-both fully accessible in the DM3730CUSD100 CUS package.

Is the DM3730CUSD100 pin-compatible with other DM3730 variants like DM3730CUSB100?

No, the DM3730CUSD100 is not pin-compatible with DM3730CUSB100. The DM3730CUSD100 uses a 423-ball s-PBGA (CUS) package with 0.65mm pitch, while DM3730CUSB100 uses a 515-ball s-PBGA (CBP) package with finer 0.5mm/0.4mm pitch and POP capability. Ball assignments, power domains, and peripheral mappings differ significantly-requiring separate PCB layouts for each variant.

What operating systems are officially supported on the DM3730CUSD100?

Texas Instruments provides official software support for Linux and Windows Embedded CE on the DM3730CUSD100. TI's Processor SDK Linux includes kernel drivers, bootloader (U-Boot), and graphics libraries (SGX SDK) validated for the DM3730CUSD100. Windows Embedded CE BSPs are also available directly from TI, with full peripheral enablement including USB OTG, display subsystem, and camera ISP-ensuring production-ready deployment without third-party porting effort.
