Product details
Overview
ADSP-2186MKSTZ300R from Analog Devices is a 75 MIPS fixed-point DSP microcomputer optimized for real-time signal processing in embedded audio, telecom, and industrial control systems. It integrates 8K × 24-bit program RAM, 8K × 16-bit data RAM, dual synchronous serial ports (SPORT0/SPORT1), a 16-bit internal DMA port, and a programmable 16-bit interval timer - all operating at 13.3 ns instruction cycle time with single-cycle execution.
For engineers reviewing the ADSP-2186MKSTZ300R datasheet, ADSP-2186MKSTZ300R pinout, ADSP-2186MKSTZ300R application, or ADSP-2186MKSTZ300R equivalent, key selection criteria include its LQFP-100 package, 2.5 V core supply with 3.3 V I/O tolerance, full memory mode vs. host mode configuration flexibility, and ICE-Port™ debug interface compatibility for in-system emulation.
Technical Context
The ADSP-2186MKSTZ300R implements the ADSP-2100 base architecture with three independent computational units (ALU, MAC, shifter), two data address generators (DAG1/DAG2), and a zero-overhead loop-capable program sequencer. Its 3-bus architecture enables simultaneous dual operand fetches - one from program memory and one from data memory - within every instruction cycle.
It supports two distinct system interface modes: Full Memory Mode (Mode C = 0) with 14-bit address bus (A13:A0) and 24-bit data bus (D23:D0), and Host Mode (Mode C = 1) using a multiplexed 16-bit IDMA port (IAD15:IAD0) with dedicated control signals (IWR, IRD, IAL, IS, IACK). Pin functionality is determined at RESET and remains static during operation.

Pinout & Package
ADSP-2186MKSTZ300R is housed in a 100-lead LQFP (ST-100) package with 0.5 mm lead pitch and exposed thermal pad. Pin assignments are mode-dependent: Full Memory Mode (Mode C = 0) uses A13:A0 and D23:D0 for external memory interfacing, while Host Mode (Mode C = 1) repurposes pins for the 16-bit IDMA port (IAD15:IAD0) and control signals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RESET | Asynchronous processor reset input | Active-low signal initializing all registers, memory, and state machines; must be held low ≥ 100 ns after power stabilization |
| CLKIN / XTAL | System clock source input | Accepts 3.6864 MHz–50 MHz crystal or CMOS clock; drives internal PLL to generate core timing |
| A13:A0 | Address output (Full Memory Mode) | 14-bit multiplexed address bus for program/data/byte/I/O memory spaces; requires external latch on rising edge of CLKOUT |
| D23:D0 | Data I/O (Full Memory Mode) | 24-bit bidirectional bus; upper 8 bits (D23:D16) serve as byte memory address bits in BDMA transfers |
| IAD15:IAD0 | Address/data bus (Host Mode) | Multiplexed 16-bit bus carrying both address and data during IDMA transactions; latched by IAL signal |
| PMS / DMS / IOMS / BMS / CMS | Memory space select outputs | Individually asserted strobes enabling program, data, I/O, byte, or combined memory decoding without glue logic |
| SPORT0 / SPORT1 | Synchronous serial I/O | Each port provides separate Tx/Rx clocks, frame sync, and data lines; supports 3–16 bit word lengths and hardware µ/A-law companding |
| PF0–PF7 | Programmable flag I/O | Eight bidirectional pins configurable as inputs or outputs; three additional flags (FL0–FL2) are output-only for system signaling |
Key Features
| Feature | Design Value |
|---|---|
| Single-cycle instruction execution | Every ALU/MAC/shifter operation completes in 13.3 ns - enables deterministic latency-critical control loops |

FAQ
What is the maximum operating frequency supported by ADSP-2186MKSTZ300R?
The ADSP-2186MKSTZ300R operates with a guaranteed 13.3 ns instruction cycle time, corresponding to a maximum internal clock frequency of 75 MHz. This timing is specified under recommended operating conditions (2.5 V VDDINT, –40°C to +85°C) and is validated across process, voltage, and temperature corners. The ADSP-2186MKSTZ300R does not support overclocking beyond this rated speed.
Does ADSP-2186MKSTZ300R support external memory expansion in both Full Memory Mode and Host Mode?
Yes, ADSP-2186MKSTZ300R supports external memory expansion in both modes but with different interfaces: Full Memory Mode (Mode C = 0) uses dedicated A13:A0 and D23:D0 buses for up to 4 MB byte memory and I/O space, while Host Mode (Mode C = 1) employs the 16-bit multiplexed IDMA port (IAD15:IAD0) with IWR/IRD controls for direct access to external memory-mapped peripherals or RAM. Mode selection is hardwired at RESET and cannot be changed dynamically.
How does the ICE-Port™ interface on ADSP-2186MKSTZ300R differ from standard JTAG debug solutions?
The ICE-Port™ on ADSP-2186MKSTZ300R is a proprietary 14-pin asynchronous interface that provides full in-circuit emulation capabilities - including breakpoints, register/memory read/write, and C-source debugging - without requiring JTAG boundary scan logic or shared pins with functional I/O. Unlike JTAG, ICE-Port™ operates independently of the DSP's normal execution state and does not consume CPU cycles or require special debug instructions, enabling true non-intrusive real-time analysis.
Can ADSP-2186MKSTZ300R boot directly from external parallel EPROM without external logic?
Yes, ADSP-2186MKSTZ300R supports automatic booting from byte-wide external memory (e.g., EPROM) in Full Memory Mode via its BDMA controller. Upon reset, it executes a predefined boot sequence that loads the first 8K words of program memory from external byte memory starting at address 0x000000, using BMS and RD/WR strobes. No external glue logic is required - the ADSP-2186MKSTZ300R generates all necessary control signals internally.
What are the power management capabilities of ADSP-2186MKSTZ300R?
The ADSP-2186MKSTZ300R features three low-power states: Power-Down (enters sub-µA standby with 200 CLKIN-cycle wake-up), Idle (clock gated to core logic while peripherals remain active), and Slow Idle (reduced clock frequency via prescaler). Power-down is triggered by the PWD input and acknowledged via PWDACK; all states preserve on-chip RAM contents. These modes are essential for battery-powered portable audio and measurement devices where runtime extension is critical.
