ADSP-2191MKSTZ-160

Digital Signal Processor Dsp Overview

The ADSP-2191MKSTZ-160 is a digital signal processor from the ADSP-219x family, fabricated in a high-speed CMOS process. It features a 6.25 ns instruction cycle time, delivering up to 160 MIPS of sustained performance. The device integrates 64K words of on-chip SRAM, configured as 32K words of 24-bit program RAM and 32K words of 16-bit data RAM. It operates with a 2.5 V internal core voltage and 3.3 V I/O levels. The architecture includes three computational units (ALU, MAC, shifter), two Data Address Generators (DAGs), and a unified memory space allowing dual operand fetches per cycle.

Digital Signal Processor Dsp Feature Summary

• 160 MIPS performance with 6.25 ns instruction cycle time
• 64K words on-chip SRAM (32K 24-bit PM + 32K 16-bit DM)
• Three full-duplex serial ports supporting up to 128 TDM channels
• Two SPI-compatible ports and one UART port with DMA support
• 16-bit Host Port for glueless interface to 8/16-bit microcontrollers

Digital Signal Processor Dsp Applications

• Telecommunications systems requiring H.100 support and companding
• High-speed numeric processing applications
• Digital signal processing optimized for compiled C and C++ code efficiency
• Systems requiring zero-overhead looping and conditional instruction execution

Digital Signal Processor Dsp Procurement Notes

Verify package availability as the ADSP-2191M series is available in 144-lead LQFP and 144-ball Mini-BGA formats. Confirm that the specific suffix 'MKSTZ' corresponds to the required temperature range and packaging variant. Check current distribution status as older generation DSPs may have limited stock or end-of-life notifications from Analog Devices.

Digital Signal Processor Dsp Selection Notes

Select this component if code compatibility with the ADSP-218x family is required while needing enhanced architectural features like additional registers and peripherals. Ensure the application can utilize the 2.5 V core and 3.3 V I/O power domains. Verify that the 160 MIPS throughput meets the real-time processing demands of the target algorithm.

Digital Signal Processor Dsp Part Context

The ADSP-2191M belongs to the ADSP-219x family, which extends the ADSP-218x architecture. It shares code compatibility with the ADSP-218x family but offers improvements in computational units, DAGs, and the program sequencer. This lineage allows developers to migrate existing ADSP-218x codebases with minimal modification while gaining access to new peripheral capabilities.

Digital Signal Processor Dsp Replacement Considerations

Direct pin-to-pin replacements within the same package are not explicitly listed in the provided documentation. Developers should evaluate other members of the ADSP-21xx family for similar performance characteristics and peripheral sets, ensuring software compatibility with the ADSP-218x instruction set.
