Product details
Overview
ADSP-2186LBCA-160 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, supports zero-overhead looping, and integrates power-down mode with 100-cycle recovery-designed for real-time audio processing, telecom channel coding, and portable instrumentation.
For engineers reviewing the ADSP-2186LBCA-160 datasheet, ADSP-2186LBCA-160 pinout, ADSP-2186LBCA-160 application, or ADSP-2186LBCA-160 equivalent, key selection criteria include instruction cycle time, on-chip memory partitioning, serial port framing flexibility, low-power idle modes, and ICE-Port™ debug interface compatibility with final-system emulation.
Technical Context
The ADSP-2186LBCA-160 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-one from program memory and one from data memory-within each instruction cycle.
It features a 16-bit internal DMA port (IDMA) for transparent access to on-chip RAM in Host Mode, plus an 8-bit byte DMA port (BDMA) addressing up to 4 MB of external byte memory. Serial ports support hardware companding per CCITT G.711, frameless or framed operation, and programmable word lengths from 3 to 16 bits.
Key Specifications

| Package | 100-lead TQFP (14 mm × 14 mm, 0.5 mm pitch) - surface-mount compatible with industrial thermal profiles. |
Pinout & Package
ADSP-2186LBCA-160 is housed in a 100-lead thin quad flat pack (TQFP) with exposed thermal pad. Pin functionality is multiplexed: external bus pins are configured at RESET; serial port and flag pins are software-reconfigurable during runtime. Default functions apply unless modified via system control register.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLKIN / XTAL | Clock input pair | Accepts either 16.67 MHz TTL clock or parallel-resonant crystal; defines 30 ns instruction cycle. |
| SPORT0[4:0] | Synchronous serial I/O | 5-pin interface for full-duplex bitstream transfer; supports frame sync, companding, and autobuffering. |
| SPORT1[4:0] | Reconfigurable serial/flag interface | Can operate as serial port or be remapped to IRQ0/IRQ1/Flag In/Flag Out-enabling flexible system signaling. |
| PF0–PF7 | Programmable flag I/O | 13 total flags: 8 bidirectional (PF0–PF7), 3 dedicated outputs (FL0–FL2); used for handshaking, status, or GPIO. |
| IDMA[15:0] / A0 / IWR / IRD / IAL / IS / IACK | Host-mode interface bus | Enables glueless connection to external microcontrollers or FPGAs; 16-bit multiplexed address/data with handshake signals. |
| PWD / PWDACK | Power management control | PWD initiates hardware power-down; PWDACK confirms entry into low-power dormant state. |
Key Features
| Feature | Design Value |
|---|---|
| Single-cycle context switch | Enables deterministic interrupt response ≤30 ns-critical for hard real-time audio buffering and telecom frame alignment. |
| Dual DAG architecture | Supports simultaneous circular buffer addressing for FFTs and FIR filters without software pointer management overhead. |
| ICE-Port™ emulator interface | 14-pin debug interface enabling in-circuit emulation, breakpoint insertion, and C-level debugging in production hardware. |
| Programmable interval timer | 16-bit TCOUNT with 8-bit TSCALE prescaler-generates precise periodic interrupts for sample-rate timing or scheduler ticks. |
| Low-power operation modes | Three states: Power-Down (100-cycle wake), Idle (indefinite wait), Slow Idle (16×/32×/64×/128× clock divisor)-extends battery life in portable DSP systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-point DSP microcomputer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADSP-2189MKSTZ-160 | Same 100-lead TQFP package, 33 MIPS, but adds 2K × 24-bit boot ROM and enhanced UART emulation via SPORT reconfiguration. | Preferred for systems requiring standalone boot from internal ROM without external EPROM; lacks ADSP-2186LBCA-160's dedicated flag pin count. | Select ADSP-2189MKSTZ-160 when ROM-based boot and UART-like serial protocol are required over maximum flag I/O flexibility. |
| TMS320C549PGE | 16-bit fixed-point DSP in 144-pin LQFP; 100 MIPS peak, 32K × 16-bit RAM, but no integrated serial ports-requires external McBSP or UART. | Better suited for high-throughput, memory-intensive tasks (e.g., wideband speech coding); increases BOM cost and PCB area due to external interface ICs. | Choose TMS320C549PGE only when raw MIPS and RAM capacity outweigh integration benefits and board space constraints of ADSP-2186LBCA-160. |
Compared with ADSP-2186LBCA-160, ADSP-2189MKSTZ-160 trades flag I/O headroom for boot ROM convenience, while TMS320C549PGE delivers higher compute density at the cost of external interface components and larger footprint-making ADSP-2186LBCA-160 optimal for compact, self-contained DSP subsystems with balanced I/O and memory needs.

FAQ
What clock source options does the ADSP-2186LBCA-160 support?
The ADSP-2186LBCA-160 accepts either a 16.67 MHz TTL-compatible clock signal applied to CLKIN (with XTAL left unconnected), or a parallel-resonant fundamental-mode crystal connected across CLKIN and XTAL pins. The internal oscillator circuit automatically stabilizes the crystal; capacitor values must follow the crystal manufacturer's specification. Both configurations yield a 30 ns instruction cycle time.
Does the ADSP-2186LBCA-160 support booting from external memory?
Yes, the ADSP-2186LBCA-160 supports automatic booting from external byte-wide memory such as EPROM or flash via its 8-bit byte DMA port (BDMA). During reset, it loads the first 64 words of program code from external memory into on-chip program RAM. This capability eliminates the need for external boot ROM in many designs and is fully configurable through the system control register.
How many external interrupts does the ADSP-2186LBCA-160 support, and what types are available?
The ADSP-2186LBCA-160 supports six external interrupts: IRQ2 (edge- or level-sensitive), IRQL0 and IRQL1 (level-sensitive), IRQE (edge-sensitive), and IRQ0/IRQ1 (reconfigurable via SPORT1). All are individually maskable except the nonmaskable power-down interrupt. Priority levels and vector addresses are fixed in hardware and documented in the ADSP-2186LBCA-160 interrupt table.
Can the ADSP-2186LBCA-160 operate in a host processor configuration?
Yes, the ADSP-2186LBCA-160 supports Host Mode via the Mode C pin during reset. In this mode, it exposes a 16-bit multiplexed IDMA port (IAD15:0) with handshake signals (IWR, IRD, IAL, IS, IACK), enabling direct connection to microcontrollers or FPGAs. Host Mode limits external addressing to A0 but provides glueless, high-bandwidth access to on-chip program and data RAM.
What debug interfaces are available on the ADSP-2186LBCA-160?
The ADSP-2186LBCA-160 integrates an ICE-Port™ emulator interface-a 14-pin dedicated debug port supporting in-circuit emulation, breakpoint insertion, register/memory inspection, and C-source-level debugging. Unlike JTAG, ICE-Port™ requires no target processor core modification and operates in final-system hardware without removing the ADSP-2186LBCA-160 from the board.
