DM3730CBPD100

Digital Signal Processor Dsp Overview

The DM3730CBPD100 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 1 GHz and a TMS320C64x+ DSP core operating at 800 MHz. The device utilizes a fixed-point instruction set with 6400 MMACS performance. Key memory resources include 32 kB L1 instruction cache for both cores, 32 kB L1 data cache for the ARM core, and 80 kB L1 data cache for the DSP core. It operates on a 1.14 V supply voltage and supports I/O voltages of 1.8 V and 3 V. The component is housed in a 515-pin sPBGA package and functions within a temperature range of -40°C to +105°C.

Digital Signal Processor Dsp Feature Summary

• Dual-core processing combining ARM Cortex-A8 (1 GHz) and C64x+ DSP (800 MHz)
• Integrated multimedia accelerators including HD video codec and display controllers
• Extensive connectivity with USB OTG, Ethernet MAC, and multiple serial interfaces

Digital Signal Processor Dsp Applications

• Digital media processors for consumer electronics
• Video surveillance systems and IP cameras
• Portable media players and handheld devices

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'D' indicates the commercial temperature grade (+105°C max) against the official datasheet. Confirm the 515-pin sPBGA footprint dimensions and pinout compatibility during PCB layout. Ensure power supply sequencing meets the 1.14 V core voltage requirements specified in the electrical characteristics table.

Digital Signal Processor Dsp Selection Notes

Select this model when high-performance multimedia processing is required alongside general-purpose computing. The inclusion of both ARM and DSP cores allows for flexible task distribution between real-time signal processing and application logic. Compare against the AM3703 if only the ARM core is needed, or the OMAP3530 if lower clock speeds are sufficient for cost optimization.

Digital Signal Processor Dsp Part Context

This component belongs to the DM37x family of DaVinci processors designed for embedded multimedia applications. It serves as a successor to earlier OMAP-based solutions, offering improved performance per watt. The CBPD100 variant specifically denotes the 1 GHz ARM core speed and commercial temperature rating within the broader DM3730 product line.

Digital Signal Processor Dsp Replacement Considerations

Direct functional replacements within the same package and pinout are limited. The DM3730CBP100 offers similar specifications but may differ in temperature rating or packaging details. Cross-family migration to Sitara processors requires significant hardware redesign due to architectural differences.
