Product details
Overview
ADSP-2187NBCA-320 from Analog Devices is a 16-bit fixed-point DSP microcomputer optimized for real-time signal processing, featuring 32K words (24-bit) program RAM, 32K words (16-bit) data RAM, 12.5 ns instruction cycle time (80 MIPS), and dual serial ports with hardware companding - deployed in telecom voice codecs, industrial motor control, and audio preprocessing systems.
For engineers reviewing the ADSP-2187NBCA-320 datasheet, ADSP-2187NBCA-320 pinout, ADSP-2187NBCA-320 application, or ADSP-2187NBCA-320 equivalent, key selection considerations include on-chip memory configuration, LQFP-100 package compatibility, 1.8 V core operation, ICE-Port™ debug support, and boot-from-byte-memory capability via BDMA port.
Technical Context
The ADSP-2187NBCA-320 implements the ADSP-2100 base architecture with three independent computational units (ALU, MAC, shifter), two dedicated DAGs for simultaneous operand fetches, and zero-overhead looping via hardware loop counters and stack. Its 3-bus Harvard architecture enables concurrent instruction fetch, data read, and data write in a single cycle.
It supports flexible system interfacing through a 16-bit internal DMA port, byte-wide BDMA port (up to 4 MB addressing), programmable wait states, and dual SPORTs with frame sync, μ-law/A-law companding, and circular buffer autobuffering - all configurable without external glue logic.

FAQ
What is the core voltage requirement for ADSP-2187NBCA-320?
The ADSP-2187NBCA-320 operates at a nominal core supply voltage of 1.8 V ±0.1 V, with I/O banks supporting 1.8 V, 2.5 V, or 3.3 V operation. All inputs tolerate up to 3.6 V regardless of I/O voltage mode, enabling safe interfacing with higher-voltage peripherals without level shifters. This dual-voltage capability simplifies system integration in mixed-supply environments.
Does ADSP-2187NBCA-320 support in-circuit debugging in production hardware?
Yes, ADSP-2187NBCA-320 includes the ICE-Port™ emulator interface, which allows full in-circuit debugging - including breakpoints, real-time trace, and register inspection - directly in the final target system without requiring special test fixtures or socketed emulators. This capability is retained across all operating modes, including power-down and idle states.
How does the boot process work for ADSP-2187NBCA-320?
The ADSP-2187NBCA-320 supports automatic booting from byte-wide external memory (e.g., EPROM or Flash) via its BDMA port, loading the first 32 program words before execution begins. Boot mode is selected at reset using the Mode C (PF2) pin configuration. Alternative boot methods include IDMA-host loading or direct execution from external memory, all configurable without firmware modification.
What memory expansion options are available for ADSP-2187NBCA-320?
ADSP-2187NBCA-320 provides three memory expansion paths: (1) 4 MB byte-addressable space via BDMA port, (2) full external data/address bus with programmable wait states for parallel memory/peripherals, and (3) 16-bit internal DMA port for high-speed host access to on-chip RAM. All interfaces support glueless connection to standard SRAM, Flash, and I/O devices.
Is ADSP-2187NBCA-320 pin-compatible with other ADSP-218xN family members?
Yes, all ADSP-218xN series devices - including ADSP-2184N, ADSP-2185N, ADSP-2186N, ADSP-2187N, ADSP-2188N, and ADSP-2189N - are fully pin-compatible in the 100-lead LQFP package. They differ only in on-chip memory size and configuration, enabling hardware reuse and scalable firmware development across the family.
