ADSP1802KCPZ400-RL

ADSP1802KCPZ400-RL is Analog Devices’ ADSP-180x series fixed-point DSP processor. It features a 16-bit DSP core with multiply-accumulate, a pipelined architecture, and a Harvard data path designed for real-time signal processing. The device typically includes programmable program and data memories, on-chip peripherals (timers, serial I/O, DMA), and fast I/O for embedded DSP tasks. It’s used in audio processing, telecommunications, motor control, and instrumentation where deterministic timing and high MAC density are advantageous. The suffixes indicate packaging and packaging/shipping details: KCPZ denotes the package type, 400 is a speed/revision code, and RL indicates reel (tape-and-reel) packaging. For development, consult Analog Devices’ toolchains and the ADSP-180x family documentation for configuring memory, pins, and peripherals.

ADSP1802KCPZ400-RL features (highlights):
- 16-bit fixed-point DSP core with hardware multiply-accumulate (MAC)
- Harvard architecture: separate program and data memories
- Up to ~40 MHz operation with DSP-optimized instruction set (MAC, shifts, circular buffering, bit-reverse addressing)
- On-chip RAM/ROM with external memory interface for expanded memory
- Peripherals: timers, serial ports, general-purpose I/O, interrupt controller
