NUC980DK71YC

Microprocessors Overview

The NUC980DK71YC is a 32-bit microprocessor IC from the NuMicro series, manufactured by Nuvoton Technology Corporation. It features an ARM926EJ-S core operating at 300 MHz with 16 KB I-cache and 16 KB D-cache. The device integrates 128 MB DDR-II memory within a single 128-LQFP (14x14 mm) package. Key peripherals include dual 10/100 Mbps Ethernet MACs, two USB 2.0 High-Speed Host/Device controllers, six USB 1.1 Host Lite interfaces, four CAN 2.0B interfaces, and a hardware cryptographic accelerator supporting AES, RSA, ECC, and SHA.

Microprocessors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS3 compliance status prior to integration. Check for End-of-Life notifications as discontinuation dates may vary by region. Ensure supply chain stability due to potential obsolescence risks associated with legacy ARM9 architectures.

Microprocessors Selection Notes

Select this model when high-density memory integration is required to minimize PCB footprint. Suitable for designs needing robust industrial connectivity via dual Ethernet and multiple CAN buses. Consider thermal management requirements for the 128-LQFP package under full load conditions.

Microprocessors Part Context

Part of the NUC980 series targeting industrial control and IoT applications. Designed to reduce BOM cost and EMI issues through stacked memory packaging. Supports Embedded Linux and FreeRTOS environments.

Microprocessors Replacement Considerations

NUC980DK63YC: Similar LQFP128 package but with 64 MB DDR-II memory instead of 128 MB.
