DM3730CUS100

Digital Signal Processor Dsp Overview

The DM3730CUS100 is a digital signal processor and controller from the Texas Instruments DaVinci series, featuring a dual-core architecture. It integrates an ARM Cortex-A8 processor running at up to 800 MHz and a TMS320C64x+ DSP core also operating at 800 MHz. The device utilizes an sPBGA-423 package and supports a 32-bit data bus width. Key memory specifications include 32 kB L1 instruction cache and 32 kB L1 data cache for the ARM core, alongside 32 kB L1 instruction cache and 80 kB L1 data cache for the DSP core. Internal storage comprises 32 kB of program memory and 64 kB of data RAM. The component operates within a temperature range of -40°C to +105°C with a core voltage of 1.14 V.

Digital Signal Processor Dsp Feature Summary

• Dual-core configuration combining ARM Cortex-A8 and TMS320C64x+ DSP cores
• Maximum clock frequency of 800 MHz for both processor cores
• Integrated multimedia capabilities with 6400 MMACS performance
• Supports multiple interfaces including USB, UART, I2S, Serial, and 1-Wire

Digital Signal Processor Dsp Applications

• Wireless music production systems using open hardware platforms like BeagleBoard
• Embedded human tracking and computer vision applications utilizing OpenCV libraries
• Digital media processing tasks requiring low-latency audio streaming

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'CUS100' against official Texas Instruments documentation to confirm pinout compatibility and electrical characteristics relative to other DM3730 variants. Ensure that the sPBGA-423 package dimensions align with the target PCB footprint design. Confirm moisture sensitivity level requirements for manufacturing processes.

Digital Signal Processor Dsp Selection Notes

Select this component when both general-purpose processing via ARM Cortex-A8 and high-performance fixed-point digital signal processing via C64x+ are required in a single chip. Consider the 800 MHz speed limit if higher throughput is needed, as faster variants like the DM3730CBP100 offer 1 GHz operation. Evaluate the 423-ball package size against available board space constraints.

Digital Signal Processor Dsp Part Context

This part belongs to the Texas Instruments DaVinci family, designed for embedded multimedia applications. It sits alongside similar processors like the AM3703 series, which lacks the dedicated DSP core, and other DM3730 variants with different package types or clock speeds. The inclusion of the C64x+ core distinguishes it from pure MPU solutions in the Sitara lineup.

Digital Signal Processor Dsp Replacement Considerations

The DM3730CBP100 serves as a functional alternative with a 1 GHz clock speed but uses an sPBGA-515 package, requiring layout changes.
