Product details
Overview
ADSP-2185MKCAZ-300 from Analog Devices is a 24-bit fixed-point DSP microcomputer optimized for real-time signal processing in embedded audio, telecom, and industrial control systems. It delivers 75 MIPS sustained performance at 13.3 ns instruction cycle time, integrates 16K × 24-bit program RAM and 16K × 16-bit data RAM, and supports dual synchronous serial ports (SPORT0/SPORT1) with hardware companding for voice-band applications.
For engineers reviewing the ADSP-2185MKCAZ-300 datasheet, ADSP-2185MKCAZ-300 pinout, ADSP-2185MKCAZ-300 application, or ADSP-2185MKCAZ-300 equivalent, key selection considerations include its 100-lead LQFP package, 2.5 V core supply with 2.5/3.3 V I/O tolerance, ICE-Port™ debug interface, and full ADSP-2100 family code compatibility for legacy migration paths.
Technical Context
The ADSP-2185MKCAZ-300 implements the ADSP-2100 base architecture with three independent computational units-ALU, MAC, and shifter-enabling single-cycle execution of multifunction instructions. Its 3-bus architecture permits simultaneous dual operand fetches (one from program memory, one from data memory) per instruction cycle, while two dedicated DAGs support zero-overhead circular buffering and modulo addressing.
It operates in Full Memory Mode (Mode C = 0) or Host Mode (Mode C = 1), configurable at reset only. In Full Memory Mode, it exposes 14-bit address (A13:A0) and 24-bit bidirectional data (D23:D0) buses with programmable wait states, memory select signals (PMS/DMS/IOMS/BMS/CMS), and RD/WR controls-enabling direct glueless interfacing to external EPROM, SRAM, and peripherals.
Key Specifications

|---|---|
| Core Architecture | ADSP-2100 family 24-bit fixed-point DSP with ALU, MAC, and shifter computational units |
| Performance | 75 MIPS sustained at 13.3 ns instruction cycle time; all instructions execute in one cycle |
| On-Chip Memory | 16K × 24-bit program RAM + 16K × 16-bit data RAM; dual-purpose program memory supports instruction/data overlay |
| Serial Interfaces | Two independent SPORTs supporting 3–16-bit word lengths, A-law/µ-law companding per G.711, and frame sync flexibility |
| Power Supply | 2.5 V core (VDDINT), 2.5 V or 3.3 V I/O (VDDEXT); all inputs tolerate up to 3.6 V regardless of mode |

Pinout & Package
The ADSP-2185MKCAZ-300 is housed in a 100-lead LQFP (ST-100) package with 0.5 mm pitch and 14 mm × 14 mm footprint. Pin functions are mode-dependent: Full Memory Mode (Mode C = 0) activates A13:A0 address outputs and D23:D0 bidirectional data lines; Host Mode (Mode C = 1) repurposes pins for IDMA port (IAD15:IAD0, IWR, IRD, IAL, IS, IACK). All interrupt/flag pins (IRQ2/PF7 through IRQE/PF4) retain concurrent interrupt and I/O functionality.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RESET | Asynchronous processor reset input | Active-low signal that initializes all registers, clears memory pointers, and forces boot sequence; must be held low ≥ 100 ns after power stabilization |
| A13:A0 | Address output bus (Full Memory Mode) | 14-bit multiplexed address for program, data, byte, and I/O memory spaces; enables 4 MByte external memory interface |
| D23:D0 | Bidirectional data bus (Full Memory Mode) | 24-bit data path; upper 8 bits (D23:D16) serve as byte memory address bits during BDMA transfers |
| PMS/DMS/IOMS/BMS/CMS | Memory space select outputs | Individual chip-select signals for program, data, I/O, byte, and combined memory spaces-eliminates need for external address decoders |
| RD/WR | Memory control strobes | Active-low read/write enable signals synchronized to CLKIN; support programmable wait states for slow peripherals |
| SPORT0/SPORT1 | Synchronous serial I/O pairs | Each includes SCLK, RFS, TFS, DR, DT pins; supports independent framing, internal clock generation, and automatic buffer management |
| PF0–PF7 | Programmable flag I/O | 13 total flags; PF0–PF3 always I/O, PF4–PF7 share IRQ functions; software-configurable direction and state for system signaling |
| ICE-Port (EZ-Port) | Emulation interface | 14-pin dedicated debug port supporting real-time trace, breakpoint injection, and non-intrusive memory/register access without target removal |
Key Features
| Feature | Design Value |
|---|---|
| Zero-overhead looping | Hardware loop counters and stack eliminate branch overhead for repetitive operations-critical for FIR/IIR filter kernels |
| Byte DMA controller (BDMA) | Direct 8-bit memory access to external EPROM/SRAM for program overlays and coefficient tables without CPU intervention |
| Internal DMA port (IDMA) | 16-bit multiplexed address/data bus enabling high-speed transparent access to on-chip RAM from host processors or FPGAs |
| Power-down mode | CMOS standby power reduction with 200 CLKIN-cycle wake-up latency-suitable for battery-powered portable DSP systems |
| Flexible interrupt system | 11 total interrupts (6 external, 5 internal), individually maskable via IMASK register; nonmaskable power-down interrupt ensures safe state retention |

Equivalent & Alternatives
The following parts are listed as comparable options for similar DSP microcomputer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADSP-2189MKCAZ-300 | Higher clock speed (75 MHz vs. 75 MIPS effective), identical architecture and pinout, but rated for commercial temperature range only | Targeted at cost-sensitive consumer audio where extended temperature operation is not required | Select when maximum throughput is prioritized over industrial temp grade and long-term availability |
| TMS320VC5402PGE100 | TI C54x 16-bit fixed-point DSP; different instruction set, no ICE-Port, requires external boot ROM, 144-pin LQFP | Legacy TI ecosystem integration; suitable where existing C54x toolchain and libraries are mandated | Choose only if migrating from C54x design; not drop-in compatible due to architectural and debug interface differences |
Compared with ADSP-2185MKCAZ-300, the ADSP-2189MKCAZ-300 offers identical feature set with higher guaranteed clock frequency but narrower temperature rating, while the TMS320VC5402PGE100 requires full software rework and lacks integrated emulation-making ADSP-2185MKCAZ-300 preferable for new designs requiring robust debug, industrial temp, and seamless ADSP-2100 family migration.

FAQ
What is the operating voltage range for ADSP-2185MKCAZ-300?
The ADSP-2185MKCAZ-300 requires a 2.5 V ± 0.2 V supply on VDDINT for the core logic and supports either 2.5 V or 3.3 V on VDDEXT for I/O buffers. All digital inputs tolerate up to 3.6 V regardless of VDDEXT setting, enabling mixed-voltage system interfacing without level shifters. This dual-supply scheme minimizes core power while maintaining interface flexibility in ADSP-2185MKCAZ-300 designs.
Does ADSP-2185MKCAZ-300 support booting from external memory?
Yes, the ADSP-2185MKCAZ-300 supports automatic booting from byte-wide external memory (e.g., EPROM or Flash) via its Byte DMA port. During reset, it loads the first 64 words of program code from external memory into on-chip program RAM, then begins execution. This capability eliminates the need for external boot PROMs in ADSP-2185MKCAZ-300 systems and simplifies firmware updates.
How many serial ports does ADSP-2185MKCAZ-300 have, and what protocols do they support?
The ADSP-2185MKCAZ-300 integrates two fully independent synchronous serial ports (SPORT0 and SPORT1), each supporting TDM, I²S-like, and frame-synced modes with programmable word length (3–16 bits), internal/external clock sourcing, and hardware A-law/µ-law companding per CCITT G.711. These ports operate concurrently and can be configured for multichannel voice or audio streaming in ADSP-2185MKCAZ-300 applications.
What debug interface is provided on ADSP-2185MKCAZ-300?
The ADSP-2185MKCAZ-300 features a dedicated 14-pin ICE-Port™ interface compliant with Analog Devices' EZ-ICE® emulator standard. This interface enables non-intrusive in-circuit debugging-including breakpoints, real-time register/memory inspection, instruction-level stepping, and boot emulation-without removing the ADSP-2185MKCAZ-300 from the target board or adding external adapters.
Is ADSP-2185MKCAZ-300 pin-compatible with other ADSP-2100 family members?
The ADSP-2185MKCAZ-300 shares the same 100-lead LQFP package and core pinout as ADSP-2181/2185/2189 variants, but differs in memory interface signal mapping and ICE-Port pin assignment. While software is fully code-compatible within the ADSP-2100 family, hardware layout requires verification against the specific variant's pin configuration table-ADSP-2185MKCAZ-300 is not a drop-in replacement for all members without schematic review.
