ADSP1802KCPZ400-RL

ADSP1802KCPZ400-RL is an Analog Devices fixed‑point DSP in the ADSP-1800 family. It’s a high‑pin, 400‑pin LQFP device (KCPZ package) with reel packaging (RL). The part is designed for real‑time DSP tasks and typically features a fixed‑point DSP core with fast multiply‑accumulate (MAC), a parallel program/data memory interface, and a range of on‑chip/peripheral I/O options typical of the 1800 family.
Key points:
- Core: fixed‑point DSP suitable for real‑time signal processing (filters, audio, telecom, control).
- Memory: external program and data memory interface for large working datasets.
- Peripherals: I/O options, timers, and serial interfaces common to ADSP‑1800 devices; includes DMA capabilities on many variants.
- Package/Packaging: 400 pins in KCPZ; RL denotes reel packaging.
- Use: embedded applications requiring deterministic DSP performance.
- Tools: development with Analog Devices’ VisualDSP++ legacy tools or CrossCore Embedded Studio (and related evaluation boards).
Note: exact peripheral sets and memory sizes vary by device variant; consult the datasheet for pin‑level, timing, and feature details.
