ADSP-2191MKCA-160

Digital Signal Processor Dsp Overview

The ADSP-2191MKCA-160 is a fixed-point digital signal processor from the Analog Devices ADSP-219x family, fabricated in a high-speed CMOS process. It features a 16-bit DSP core with up to 160 MIPS sustained performance, driven by a 6.25 ns instruction cycle time at a maximum clock frequency of 160 MHz. The device integrates 160 KB of on-chip SRAM, configured as 32K words of 24-bit program RAM and 32K words of 16-bit data RAM, alongside 1K word of boot ROM. It operates with a 2.5 V internal supply and 3.3 V I/O levels, housed in a 144-lead Mini-BGA package.

Digital Signal Processor Dsp Feature Summary

• ADSP-218x family code-compatible architecture with enhanced computational units and dual Data Address Generators (DAGs).
• Integrated peripherals include three full-duplex serial ports, two SPI-compatible ports, one UART, and a 16-bit Host port with DMA support.
• Supports up to 16M words of addressable external memory via a 16-bit External Memory Interface.
• Features flexible power management with user-selectable power-down and idle modes.

Digital Signal Processor Dsp Applications

• Telecommunications systems requiring TDM channel processing.
• High-speed numeric processing applications.
• Digital signal processing optimized for compiled C and C++ code efficiency.

Digital Signal Processor Dsp Procurement Notes

Verify the specific ordering suffix 'KCA' against the manufacturer's current datasheet to confirm package type and temperature range. Confirm availability status as legacy components may have limited stock or end-of-life notifications. Ensure compatibility with existing PCB footprints for the 144-ball Mini-BGA configuration.

Digital Signal Processor Dsp Selection Notes

Select this model if code compatibility with the ADSP-218x family is required while needing higher performance. Choose based on the need for 160 MIPS throughput and 160 KB of unified on-chip memory. Consider the 144-lead Mini-BGA package constraints for board layout and thermal management requirements.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-219x series, which extends the ADSP-218x architecture. It shares instruction set compatibility but offers architectural enhancements such as additional registers and improved peripheral integration. The 'MKCA' suffix typically denotes the Mini-BGA package variant within the 2191M product line.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements within the same family include other ADSP-2191M variants with different speed grades or packages, such as ADSP-2191MKSTZ. Cross-family migration to newer SHARC processors requires significant software and hardware redesign due to architectural differences.
