Product details
Overview
ADSP-2191MKCAZ-160 from Analog Devices is a 160 MIPS fixed-point DSP microcomputer with dual-memory architecture (32K × 24-bit program RAM + 32K × 16-bit data RAM), three full-duplex serial ports, two SPI-compatible ports, UART, and 16-bit host interface - deployed in telecom infrastructure, audio processing, and real-time control systems.
For engineers reviewing the ADSP-2191MKCAZ-160 datasheet, ADSP-2191MKCAZ-160 pinout, ADSP-2191MKCAZ-160 application, or ADSP-2191MKCAZ-160 equivalent, key selection criteria include instruction cycle time (6.25 ns), on-chip memory configuration, serial port count and TDM channel support (up to 128), programmable PLL range (1×–32×), and 144-lead LQFP package compatibility.
Technical Context
The ADSP-2191MKCAZ-160 implements a three-unit computational core (ALU, MAC with dual 40-bit accumulators, barrel shifter) with zero-overhead looping, dual DAGs for circular buffering, and unified 24-bit address space enabling simultaneous program/data fetches. Its instruction set supports single-cycle execution of multifunction instructions (e.g., data move + ALU operation).
System-level integration includes a 16-bit external memory interface (22-bit address bus), glueless 8/16-bit host port with DMA, JTAG-compliant emulation, and power management with user-selectable idle/power-down modes - all operating at 2.5 V core / 3.3 V I/O.

FAQ
What is the maximum external memory address space supported by the ADSP-2191MKCAZ-160?
The ADSP-2191MKCAZ-160 supports up to 16M words (22-bit address bus) of external memory space, divided into four configurable banks (Bank 0–3) selectable via MS3–MS0 pins. Each bank can be assigned variable page boundaries and wait-state parameters, enabling flexible interfacing with SRAM, Flash, or FIFO devices across diverse timing requirements.
Does the ADSP-2191MKCAZ-160 support IEEE JTAG 1149.1 for in-circuit debugging?
Yes, the ADSP-2191MKCAZ-160 integrates a full IEEE 1149.1-compliant JTAG Test Access Port (TAP) controller supporting boundary-scan testing, on-chip emulation, and real-time debug features such as hardware breakpoints, register inspection, and memory read/write - all without halting real-time serial or timer operations.
How many DMA channels does the ADSP-2191MKCAZ-160 support simultaneously?
The ADSP-2191MKCAZ-160 supports up to 11 active DMA channels concurrently - including dedicated channels for each SPORT (0–2), SPI (0–1), UART, Host Port, and Memory DMA. Channel arbitration follows fixed priority (SPORT0 Rx highest), ensuring predictable latency for time-critical I/O like TDM voice streams.
Can the ADSP-2191MKCAZ-160 boot directly from an external SPI flash device?
Yes, the ADSP-2191MKCAZ-160 supports SPI-based booting via its integrated boot ROM. When configured with BMODE[1:0] = 10, the device initializes from an external SPI ROM connected to SPI0, executing autobaud-detect initialization and loading firmware into on-chip RAM - eliminating need for external boot controllers.
What voltage levels are required for core and I/O operation of the ADSP-2191MKCAZ-160?
The ADSP-2191MKCAZ-160 requires 2.5 V ± 0.1 V for internal core operation and 3.3 V ± 0.3 V for all I/O interfaces (SPORTs, SPI, UART, Host Port, PF pins). Separate power domains allow independent sequencing, and the device includes internal regulators and power-on reset circuitry to ensure reliable startup under specified voltage tolerances.
