Product details
Overview
ADSP-2186LKSTZ-133 from Analog Devices is a 33 MIPS fixed-point DSP microcomputer with 16K × 24-bit on-chip program RAM, 16K × 16-bit on-chip data RAM, and dual 5-pin synchronous serial ports (SPORT0/SPORT1). It executes all instructions in a single 30 ns cycle and supports zero-overhead looping for real-time audio filtering and telecom signal processing.
For engineers reviewing the ADSP-2186LKSTZ-133 datasheet, ADSP-2186LKSTZ-133 pinout, ADSP-2186LKSTZ-133 application, or ADSP-2186LKSTZ-133 equivalent, key selection criteria include instruction cycle time, on-chip memory configuration, serial port framing flexibility, power-down recovery latency, and ICE-Port™ debug interface compatibility.
Technical Context
The ADSP-2186LKSTZ-133 implements the ADSP-2100 family base architecture with three independent computational units (ALU, MAC, shifter), two dedicated data address generators (DAG1/DAG2), and a zero-overhead program sequencer supporting conditional jumps and subroutine calls in one cycle. Its 3-bus architecture enables simultaneous dual operand fetches from program and data memory.
It integrates a 16-bit internal DMA port (IDMA) for transparent access to on-chip RAM, an 8-bit byte DMA port (BDMA) addressing up to 4 MB external memory, and a programmable 16-bit interval timer with prescaler. Serial ports support hardware A-law/µ-law companding per CCITT G.711 and frameless or framed operation with independent transmit/receive synchronization.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Instruction Cycle Time | 30 ns - enables 33 MIPS sustained throughput for real-time FIR/IIR filter execution without pipeline stalls. |
| On-Chip Program Memory | 16K × 24-bit RAM - stores both instructions and constants; eliminates external program memory for compact embedded DSP designs. |
| On-Chip Data Memory | 16K × 16-bit RAM - supports dual-operand fetches per cycle; sufficient for 1024-point FFT buffers or multi-channel audio sample storage. |
| Serial Ports | 2 × 5-pin SPORTs - each provides double-buffered TX/RX with hardware companding and independent framing control for TDM or ISDN interfaces. |
| Power-Down Recovery | 100 CLKIN cycles - allows rapid wake-up from ultra-low-power state for battery-powered voice recorders or sensor nodes. |
| Timer Resolution | Programmable 16-bit counter with 8-bit prescaler - generates precise periodic interrupts for sample rate timing (e.g., 8 kHz, 16 kHz, 48 kHz). |
| Interrupt Sources | 11 total (6 external + 5 internal) - includes edge/level-configurable IRQ pins and SPORT/BDMA/timer interrupts for deterministic real-time response. |
Pinout & Package
ADSP-2186LKSTZ-133 is housed in a 100-lead thin quad flat package (TQFP) with 0.5 mm pitch, compliant with JEDEC MO-153. Pin functions are multiplexed during reset (mode pins) or runtime (SPORT/flag reconfiguration); default states apply unless modified by software or external pull resistors.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLKIN / XTAL | Clock input pair | Accepts either 16.67 MHz TTL clock or parallel-resonant crystal; determines 30 ns instruction cycle; XTAL left unconnected when using external clock. |
| SPORT0[4:0] | Synchronous serial interface | 5-pin bidirectional port supporting TDM, frame sync, and companding; DT0/DR0 handle data; TFS0/RFS0 manage framing; SCLK0 supplies clock. |
| SPORT1[4:0] | Reconfigurable serial/flag interface | Software-selectable between serial I/O and IRQ0/IRQ1/FLAG_IN/FLAG_OUT; enables flexible peripheral signaling without additional GPIO. |
| PF0–PF7 | Programmable flag I/O | 8 pins configurable as inputs/outputs; PF0–PF2 serve dual role as mode select (Mode A/B/C) during reset; FL0–FL2 are dedicated output flags. |
| IDMA Port (IAD15:0, IWR, IRD, IAL, IS, IACK) | Host-mode external interface | 16-bit multiplexed address/data bus with control signals; enables glueless connection to microcontrollers or FPGAs in host mode (Mode C = 1). |
| PWD / PWDACK | Power management control | PWD initiates hardware power-down; PWDACK asserts low when device enters dormant state - critical for system-level power sequencing. |
Key Features
| Feature | Design Value |
|---|---|
| Single-cycle context switch | Enables deterministic interrupt latency ≤30 ns - essential for hard real-time audio buffering and echo cancellation. |
| Dual operand fetch per instruction | Leverages 3-bus architecture to load two data operands and execute ALU/MAC/shifter operations simultaneously - maximizes compute density per cycle. |
| ICE-Port™ debug interface | 14-pin dedicated emulation port supporting in-target debugging, 20 breakpoints, and C-source-level trace without removing chip from PCB. |
| Bit manipulation instructions | Includes bit set/clear/toggle/test - accelerates protocol stack bit-field handling (e.g., HDLC flag detection, packet header parsing). |
| Automatic boot from byte memory | Loads program code directly from EPROM or flash via BDMA port at power-on - eliminates need for external boot ROM or loader firmware. |

FAQ
What is the maximum external memory bandwidth supported by ADSP-2186LKSTZ-133 in Full Memory Mode?
ADSP-2186LKSTZ-133 supports up to 24-bit data bus width and 14-bit address bus (A13:A0) in Full Memory Mode, enabling direct access to 16 MB of combined program/data/byte/I/O space. The BDMA port operates at up to 133 MHz effective transfer rate when synchronized to the internal clock, allowing sustained 8 MB/s throughput to external EPROM or SRAM.
Does ADSP-2186LKSTZ-133 support IEEE 754 floating-point arithmetic natively?
No, ADSP-2186LKSTZ-133 is a fixed-point DSP with 24-bit program word and 16-bit data word architecture. It lacks hardware floating-point units. Floating-point operations must be implemented in software using Q-format arithmetic or library functions from the ADSP-2100 Family Runtime Library, with performance penalties versus native fixed-point execution.
Can SPORT0 and SPORT1 operate simultaneously at different bit widths and framing modes?
Yes, ADSP-2186LKSTZ-133 allows independent configuration of SPORT0 and SPORT1. Each port supports serial word lengths from 3 to 16 bits, selectable framing (internal/external sync, active-high/inverted), and optional A-law/µ-law companding. This enables concurrent TDM voice stream handling on SPORT0 and control channel communication on SPORT1 within the same application.
How does the ADSP-2186LKSTZ-133 handle interrupt nesting and priority resolution?
ADSP-2186LKSTZ-133 implements hardware-managed interrupt nesting with fixed priority levels defined in Table I of its datasheet. Reset has highest priority (0000h), timer lowest (0028h). The IMASK register individually enables/disables interrupts, and the ICNTL register configures edge/level sensitivity for IRQ0–IRQ2. Nested servicing preserves full context via 12-level hardware stacks.
Is the ICE-Port™ interface on ADSP-2186LKSTZ-133 compatible with standard JTAG debuggers?
No, ICE-Port™ is a proprietary Analog Devices emulation interface distinct from JTAG. It uses a 14-pin connector and protocol optimized for ADSP-21xx architecture, requiring ADI's EZ-ICE® emulator hardware and VisualDSP++ software. Standard JTAG tools cannot communicate with ADSP-2186LKSTZ-133 via ICE-Port™ without protocol translation hardware.
