ADSP-2191MBCAZ-140

Digital Signal Processor Dsp Overview

The ADSP-2191MBCAZ-140 is a fixed-point 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 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. Key architectural components include an ALU, multiplier/accumulator, barrel shifter, two Data Address Generators (DAGs), and a program sequencer supporting zero-overhead looping.

Digital Signal Processor Dsp Feature Summary

• ADSP-219x DSP Core with single-cycle execution for most instructions and dual operand fetch capability via unified memory space.
• Integrated peripherals including three full-duplex serial ports, two SPI-compatible ports, one UART, and a 16-bit Host port with DMA support.
• Six independent DMA channels enabling automated data transfers between internal memory, external memory, and peripherals without core intervention.
• Three programmable interval timers capable of PWM generation, pulsewidth capture, and external event counting.

Digital Signal Processor Dsp Applications

• Digital signal processing laboratory environments utilizing assembly language programming and advanced algorithm implementation.
• Telecommunications systems requiring H.100 support and TDM channel handling with A-law/μ-law companding.
• High-speed numeric processing applications demanding efficient code execution through pipelined architecture and compiled C/C++ optimization.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix BCZA against the manufacturer's ordering guide to confirm package type and temperature range. Confirm that the 140 designation aligns with the standard 160 MHz clock speed specifications found in the datasheet. Ensure compatibility with 2.5 V core and 3.3 V I/O power requirements during system design validation.

Digital Signal Processor Dsp Selection Notes

Select this component when code compatibility with the ADSP-218x family is required alongside enhanced computational flexibility. Choose the ADSP-2191M for applications needing extensive on-chip memory and multiple serial interfaces. Consider the 144-lead LQFP or Mini-BGA packages based on board space constraints and thermal management needs.

Digital Signal Processor Dsp Part Context

The ADSP-2191M belongs to the ADSP-21xx series, specifically the ADSP-219x family. This family represents an evolution of the ADSP-218x architecture, offering improved DAG units and program sequencer capabilities while maintaining binary compatibility. It serves as a bridge between legacy 218x designs and more modern mixed-signal controllers like the ADSP-2199x series.

Digital Signal Processor Dsp Replacement Considerations

The ADSP-2191MKCAZ-140 is a direct pin-compatible alternative within the same package family. For higher integration with analog peripherals, the ADSP-21991 offers mixed-signal capabilities but requires architectural adaptation due to different peripheral sets.
