Product details
Overview
ADSP-2191MKCA-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, one UART, and 16-bit host interface - deployed in telecom infrastructure, audio processing, and real-time control systems.
For engineers reviewing the ADSP-2191MKCA-160 datasheet, ADSP-2191MKCA-160 pinout, ADSP-2191MKCA-160 application, or ADSP-2191MKCA-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-2191MKCA-160 implements a pipelined Harvard architecture with three independent computational units (ALU, MAC, barrel shifter), two 16-bit DAGs with 40-bit accumulators, and unified 24-bit address space enabling simultaneous dual-operand fetches from program and data memory. Its program sequencer delivers zero-overhead looping and conditional execution.
It integrates a 16-bit external memory interface (22-bit address bus), DMA controller supporting up to 11 concurrent channels, JTAG-compliant test access port, and flexible 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 operating frequency of the ADSP-2191MKCA-160?
The ADSP-2191MKCA-160 operates at a 6.25 ns instruction cycle time, delivering sustained 160 MIPS performance. Its internal PLL supports input clock multiplication from 1× to 32×, allowing flexible system clock derivation from low-frequency crystals or oscillators - all while maintaining full functional specification compliance across its rated temperature range.
Does the ADSP-2191MKCA-160 support booting from external memory?
Yes, the ADSP-2191MKCA-160 supports multiple boot modes via its on-chip 1K-word boot ROM, including booting from an external 8- or 16-bit host device, SPI ROM, or UART with autobaud detection. The BMODE1–0 pins configure the boot source, and the boot ROM initializes the core before transferring control to user code stored in external or internal memory.
How many serial communication interfaces does the ADSP-2191MKCA-160 integrate?
The ADSP-2191MKCA-160 integrates three full-duplex synchronous serial ports (SPORT0–SPORT2), two SPI-compatible ports (SPI0–SPI1), and one asynchronous UART port - all with DMA support. Each SPORT supports up to 128 TDM channels and hardware A-law/μ-law companding, making ADSP-2191MKCA-160 ideal for multi-channel voice and data aggregation.
Is the ADSP-2191MKCA-160 pin-compatible with other ADSP-219x family members?
The ADSP-2191MKCA-160 shares the same 144-lead LQFP package and pinout with other ADSP-2191M variants (e.g., ADSP-2191MSTZ-160 uses mini-BGA). However, it is not pin-compatible with ADSP-2192 or ADSP-2196 derivatives due to differences in peripheral register mapping and signal assignment - always verify pin function tables before substitution.
What power supply voltages does the ADSP-2191MKCA-160 require?
The ADSP-2191MKCA-160 requires two separate supply rails: 2.5 V ± 0.2 V for the core logic and 3.3 V ± 0.3 V for I/O buffers. Decoupling capacitors must be placed per Analog Devices' layout guidelines, and the power-on reset sequence must meet minimum ramp time and voltage monotonicity requirements specified in the datasheet for reliable initialization of ADSP-2191MKCA-160.
