Product details

Connectivity is a strong suit: Ethernet MAC, CAN 2.0B, USB OTG, plus multiple SPI, I²C, UART, and I²S interfaces. The 82 GPIOs in the 100-pin LQFP package provide enough headroom for parallel displays, external memory buses, and sensor arrays.

Peripheral set – Ethernet, CAN, and display support in one package

The integrated Ethernet MAC with dedicated DMA and IEEE 1588 support enables real-time industrial Ethernet stacks (EtherCAT, PROFINET) without an external PHY management chip. The CAN 2.0B interface handles legacy fieldbus integration. An LCD parallel interface and a built-in DMA controller offload the CPU for display refresh and data movement.
