ADSP-2186MKCA-300

Digital Signal Processor Dsp Overview

The ADSP-2186MKCA-300 is a fixed-point digital signal processor from the ADSP-2100 family, fabricated in a high-speed CMOS process. It features a 75 MHz maximum clock frequency with a 13.3 ns instruction cycle time, delivering 75 MIPS sustained performance. The device integrates 40 Kbytes of on-chip RAM, configured as 8K words (24-bit) of program memory and 8K words (16-bit) of data memory. It operates at a core voltage of 2.5 V with I/O voltages supporting 2.5 V or 3.3 V. The component is housed in a 144-ball Mini-BGA package.

Digital Signal Processor Dsp Feature Summary

• ADSP-2100 base architecture with three independent computational units: ALU, MAC, and shifter.
• Single-cycle execution for all instructions with zero-overhead looping via internal loop counters.
• Dual buffered synchronous serial ports (SPORT0/SPORT1) with hardware companding support.
• Flexible memory interface modes including Full Memory Mode and Host Mode with IDMA port.

Digital Signal Processor Dsp Applications

• Digital signal processing applications optimized for high-speed numeric processing.
• Battery-operated portable equipment utilizing low power dissipation and power-down modes.
• Audio processing systems leveraging SPORT interfaces and companding hardware.
• Multiprocessor communication systems using serial ports and interrupt capabilities.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix MKCA-300 against the manufacturer's current ordering guide to confirm package type and speed grade. Check for product change notices regarding availability status, as older DSP models may have discontinuation updates. Ensure environmental compliance documentation matches the required RoHS standards for the target application.

Digital Signal Processor Dsp Selection Notes

Select this model when code compatibility with the broader ADSP-2100 family is required alongside specific memory configurations. Choose the Mini-BGA package if board space constraints necessitate a smaller footprint compared to the LQFP option. Verify that the 2.5 V core voltage and 3.3 V tolerant I/O levels align with the system's power supply design.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-2186M series, which extends the ADSP-2100 architecture. It shares architectural similarities with variants like the ADSP-2189M but differs in specific pinouts and package options. The MKCA-300 designation specifically identifies the 144-ball Mini-BGA package variant operating at the 75 MHz speed grade.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements within the same family include other ADSP-2186M variants such as the LQFP package version. Cross-family migration to SHARC processors requires significant software and hardware redesign due to architectural differences.
