Product details
Overview
ADSP-2189NBCAZ-320 from Analog Devices is a 16-bit fixed-point DSP microcomputer in the ADSP-218xN family, optimized for real-time signal processing. It delivers 80 MIPS sustained performance at 12.5 ns instruction cycle time (1.8 V core), integrates 32K words of on-chip program RAM and 48K words of data RAM, and features dual serial ports (SPORT0/SPORT1), 16-bit internal DMA port, and programmable 16-bit interval timer - deployed in audio codecs, telecom line cards, and industrial motor control systems.
For engineers reviewing the ADSP-2189NBCAZ-320 datasheet, ADSP-2189NBCAZ-320 pinout, ADSP-2189NBCAZ-320 application, or ADSP-2189NBCAZ-320 equivalent, key selection criteria include on-chip memory configuration (32K × 24-bit PM / 48K × 16-bit DM), LQFP-100 package compatibility, 1.8 V core supply with 3.3 V I/O tolerance, ICE-Port™ debug interface support, and boot-from-byte-memory capability via BDMA.
Technical Context
The ADSP-2189NBCAZ-320 implements the ADSP-2100 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 nested loops. Its 3-bus architecture enables simultaneous dual operand fetches - one from program memory and one from data memory - in every instruction cycle.
It supports flexible system interfacing via 16-bit internal DMA port (IDMA), byte-wide DMA (BDMA) for up to 4 MB external memory, programmable wait states, and dual double-buffered serial ports with hardware A-law/μ-law companding per CCITT G.711. Power management includes software- or hardware-initiated power-down mode with 200 CLKIN-cycle recovery and Slow Idle mode with configurable clock divisors (16/32/64/128).

FAQ
What is the core supply voltage requirement for ADSP-2189NBCAZ-320?
The ADSP-2189NBCAZ-320 requires a 1.8 V ± 0.1 V core supply (VDDINT) for operation at its rated 80 MIPS performance and 12.5 ns instruction cycle time. I/O banks support 1.8 V, 2.5 V, or 3.3 V operation independently, and all input pins tolerate up to 3.6 V regardless of selected VDDIO level. This dual-voltage capability allows direct interfacing with legacy 3.3 V peripherals without level shifters. The ADSP-2189NBCAZ-320 datasheet specifies strict decoupling requirements: minimum 10 μF bulk capacitance plus 0.1 μF ceramic capacitors near each VDDINT pin.
Does ADSP-2189NBCAZ-320 support automatic boot from external memory?
Yes, ADSP-2189NBCAZ-320 supports automatic boot from byte-wide external memory (e.g., EPROM or Flash) using its Byte DMA (BDMA) port. When configured in Mode C = 0 and Mode A = 0 (per Table 2), the device loads the first 32 words of program memory from byte memory space before starting execution. This eliminates need for external boot ROM controllers or FPGA glue logic. The ADSP-2189NBCAZ-320 retains full access to BDMA during runtime for program overlays and data table updates, maintaining system flexibility after boot.
How many serial ports does ADSP-2189NBCAZ-320 include, and what are their key capabilities?
The ADSP-2189NBCAZ-320 integrates two fully independent synchronous serial ports (SPORT0 and SPORT1), each with double-buffered transmit/receive sections, programmable frame sync, and hardware A-law/μ-law companding per CCITT G.711. Each port supports 3–16 bit word lengths, internal or external serial clock generation, and circular buffer autobuffering with one-cycle overhead per word. SPORT0 additionally supports multichannel TDM (24- or 32-word streams), while SPORT1 can be reconfigured to provide two external interrupt inputs (IRQ0/IRQ1) alongside FI/FO signaling - all without sacrificing serial functionality.
What debug interface is supported by ADSP-2189NBCAZ-320?
ADSP-2189NBCAZ-320 supports the ICE-Port™ emulator interface, a proprietary Analog Devices debug architecture that enables full in-circuit emulation, real-time trace, hardware breakpoints, and register/memory inspection directly in the target system. Unlike standard JTAG, ICE-Port provides non-intrusive program flow monitoring and cycle-accurate timing analysis - critical for validating real-time DSP behavior. The ADSP-2189NBCAZ-320 requires an ADZS-ICE-100B or compatible emulator pod; no additional boundary-scan logic or debug firmware is needed on the target board.
Is ADSP-2189NBCAZ-320 pin-compatible with other ADSP-218xN family members?
Yes, ADSP-2189NBCAZ-320 is fully pin-compatible with all ADSP-218xN series devices in the same package variant - specifically the 100-lead LQFP (e.g., ADSP-2184N, ADSP-2185N, ADSP-2188N). This allows direct substitution based on on-chip memory requirements (32K/48K vs. 4K/4K or 48K/56K) without PCB redesign. All signal names, power/ground pin locations, and boot mode pin assignments (PF0–PF2) match exactly across the LQFP-100 variants. The ADSP-2189NBCAZ-320 shares identical timing specifications and electrical characteristics with its family members, ensuring drop-in functional replacement.
