DM3730CBC

Digital Signal Processor Dsp Overview

The DM3730CBC is a digital media processor from the Texas Instruments DaVinci family, featuring a dual-core architecture. It integrates an ARM Cortex-A8 core and a TMS320C64x+ DSP core, both operating at a maximum clock frequency of 800 MHz. The device utilizes a fixed-point instruction set and includes 64 kB of data RAM alongside 32 kB of L1 cache for both instruction and data memory on the ARM core, and 80 kB of L1 data cache on the DSP. It operates at a supply voltage of 1.14 V and supports I/O voltages of 1.8 V and 3 V. The processor is housed in an sPBGA-515 package and functions within a temperature range of -40°C to +105°C.

Digital Signal Processor Dsp Feature Summary

• Dual-core architecture combining ARM Cortex-A8 and TMS320C64x+ DSP cores
• Maximum clock frequency of 800 MHz for both processing cores
• Integrated memory structure including 64 kB data RAM and dedicated L1 caches
• Support for multiple interfaces including USB, UART, I2S, and Serial communication

Digital Signal Processor Dsp Applications

• Digital video recording and playback systems
• Portable media players and multimedia devices
• Industrial control applications requiring real-time signal processing

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'CBC' against the official Texas Instruments datasheet to confirm pinout, package dimensions, and electrical characteristics. Ensure compatibility with required I/O voltage levels (1.8 V or 3 V) and operating temperature ranges (-40°C to +105°C). Confirm moisture sensitivity level requirements for assembly processes.

Digital Signal Processor Dsp Selection Notes

Select this component when a combination of general-purpose processing and high-performance digital signal processing is required. The 800 MHz speed suits applications needing efficient media decoding. Compare with the AM3703CBC if floating-point arithmetic is preferred over the fixed-point C64x DSP capabilities. Verify that the 515-pin sPBGA package fits the target PCB layout constraints.

Digital Signal Processor Dsp Part Context

The DM3730CBC belongs to the DM3730 series of DaVinci Digital Media Processors. This series is designed to handle complex multimedia tasks by leveraging the synergy between the ARM application processor and the C64x+ DSP. It serves as a central processing unit for embedded systems requiring robust media handling and control logic.

Digital Signal Processor Dsp Replacement Considerations

The AM3703CBC is a related single-core ARM Cortex-A8 processor within the Sitara family, lacking the C64x+ DSP core. For direct functional replacement maintaining the dual-core DSP capability, verify availability of other DM3730 variants such as DM3730CBPD100, noting differences in clock speeds and packaging.
