Product details
Overview
ADSP-2195MKCA-160 from Analog Devices is a 160 MIPS fixed-point DSP microcomputer with dual 40-bit accumulators, 32K words of on-chip RAM (16K × 24-bit program RAM + 16K × 16-bit data RAM), and 16K × 24-bit on-chip ROM. It features three full-duplex multichannel serial ports compliant with H.100, two SPI-compatible ports, one UART, and a 16-bit glueless host port - deployed in telecom voice processing, audio codec control, and real-time industrial signal analysis.
For engineers reviewing the ADSP-2195MKCA-160 datasheet, ADSP-2195MKCA-160 pinout, ADSP-2195MKCA-160 application, or ADSP-2195MKCA-160 equivalent, key selection criteria include its 6.25 ns instruction cycle time, 24-bit addressing width supporting up to 16M words, programmable PLL (1×–32× multiplication), 2.5 V core / 3.3 V I/O voltage compatibility, and IEEE 1149.1 JTAG debug support.
Technical Context
The ADSP-2195MKCA-160 implements a pipelined Harvard architecture with three independent computational units (ALU, MAC, barrel shifter), two 16-bit DAGs with 8-bit page registers for 24-bit addressing, and a zero-overhead program sequencer supporting conditional execution and nested loops. Its unified memory space enables flexible operand fetches - including dual-operand instructions with one operand from program memory and one from data memory in a single cycle.
Peripherals are tightly integrated via shared DMA resources: the external memory interface (22-bit address, 16-bit configurable data bus), host port (16-bit multiplexed address/data), three SPORTs with hardware A-law/μ-law companding, and three 32-bit programmable timers supporting PWM generation, pulsewidth capture, and external event watchdog modes - all accessible without CPU intervention.

FAQ
What is the maximum operating frequency of the ADSP-2195MKCA-160?
The ADSP-2195MKCA-160 achieves sustained 160 MIPS performance with a 6.25 ns instruction cycle time. This is enabled by its internal PLL, which multiplies a lower-frequency external clock (e.g., 5 MHz) up to 160 MHz. The device does not require an external 160 MHz clock source - the PLL synthesizes the core clock internally. All instructions except two multiword types execute in a single cycle, ensuring predictable timing behavior critical for real-time signal processing in the ADSP-2195MKCA-160.
Does the ADSP-2195MKCA-160 support booting from external memory?
Yes, the ADSP-2195MKCA-160 supports multiple boot methods including external memory interface, SPI ports, UART port, and host interface. Booting from external memory uses the MS3–0 bank select pins to configure the initial memory map, and the processor fetches the first instruction from the configured external bank after reset. The on-chip 1K-word boot ROM (located on Page 255) provides fallback initialization routines if peripheral boot fails. This flexibility is documented in the "Booting Modes" section of the ADSP-2195 preliminary datasheet.
How many DMA channels does the ADSP-2195MKCA-160 support simultaneously?
The ADSP-2195MKCA-160 supports up to 11 active DMA channels at any given time. These channels serve the core, external memory interface, UART, three SPORTs, two SPI ports, and host port - enabling concurrent background data transfers without CPU overhead. Each channel operates independently with configurable priority, source/destination addressing, and transfer count. This capability allows the ADSP-2195MKCA-160 to sustain full-bandwidth I/O while executing intensive signal processing in parallel.
Is the ADSP-2195MKCA-160 pin-compatible with other ADSP-219x family members?
The ADSP-2195MKCA-160 shares the same 144-lead LQFP pinout with other ADSP-219x variants in the same package option (e.g., ADSP-2191MKCA-160), including identical power, ground, clock, reset, and memory interface pin assignments. However, peripheral pin mappings (e.g., SPORT signal routing, timer outputs) may differ between models due to feature subsets - always verify pin function definitions against the specific variant's datasheet. The ADSP-2195MKCA-160 is not pin-compatible with Mini-BGA variants like ADSP-21992KSTZ-160.
What development tools are supported for the ADSP-2195MKCA-160?
Analog Devices provides the VisualDSP++ integrated development environment (IDE) for the ADSP-2195MKCA-160, including C/C++ compiler, assembler, linker, simulator, and JTAG-based hardware debugger. Third-party tools such as TargetLink (dSPACE) support automatic code generation from Simulink models. Emulation is enabled via the IEEE 1149.1 JTAG port using ADZS-USB-ICE or compatible pods. All tools target the ADSP-2195MKCA-160's instruction set and memory map directly, with no abstraction layer required.
