ADSP-2195MKCA-160

Digital Signal Processor Dsp Overview

The ADSP-2195MKCA-160 is a 16-bit fixed-point digital signal processor from the Analog Devices ADSP-219x family, housed in a 144-lead Mini-BGA package. It delivers up to 160 MIPS sustained performance with a 6.25 ns instruction cycle time. The device integrates 32K words of on-chip RAM (configured as 16K words 24-bit program RAM and 16K words 16-bit data RAM) and 16K words of on-chip ROM. Operating at 2.5 V internally with 3.3 V compliant I/O, it features a pipelined architecture with dual Data Address Generators, three computational units, and extensive peripheral interfaces including three serial ports, two SPI ports, a UART, and a host port.

Digital Signal Processor Dsp Feature Summary

• 160 MIPS Performance: Executes instructions in a single cycle with a 6.25 ns internal instruction cycle time.
• Unified Memory Architecture: Combines 32K words of on-chip SRAM and 16K words of ROM in a unified 16M-word addressable space.
• Advanced Peripherals: Includes three full-duplex multichannel serial ports, two SPI-compatible ports, one UART, and a 16-bit Host Port with DMA capability.
• Power Management: Supports selectable power-down and idle modes for battery-operated applications.

Digital Signal Processor Dsp Applications

• High-speed numeric processing and digital signal processing algorithms
• Battery-powered portable equipment requiring low-power operation
• Systems requiring glueless interface to 8/16-bit microcontrollers via Host Port
• Applications utilizing hardware companding (A-law/u-law) in serial communications

Digital Signal Processor Dsp Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified suppliers. Check for obsolescence status as this is an older generation DSP. Ensure storage conditions comply with moisture sensitivity level requirements for the Mini-BGA package. Confirm that the specific MKCA suffix matches the required pinout and thermal characteristics for the target PCB design.

Digital Signal Processor Dsp Selection Notes

Select the ADSP-2195MKCA-160 when code compatibility with the ADSP-218x family is required alongside enhanced memory and peripheral features. Choose this model over the LQFP variant if board space constraints necessitate the smaller 10x10 mm Mini-BGA footprint. Ensure the application can support the 2.5 V core voltage and utilizes the available 3.3 V I/O levels. Verify that the 160 MHz clock speed meets the real-time processing demands of the specific algorithm.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-21xx series, specifically the ADSP-219x family which extends the ADSP-218x architecture. It is designed for embedded control and signal processing tasks. The 'MKCA' suffix denotes the 144-lead Mini-BGA package variant with industrial temperature range capabilities, distinguishing it from other package options like the LQFP.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements within the same family include the ADSP-2195M in LQFP packaging for form-factor changes. For higher performance needs, consider the ADSP-2191 or ADSP-21991 models, though these may require architectural adjustments due to increased memory and peripheral differences. Code migration from ADSP-218x is supported but requires verification of peripheral usage.
