The COM20019I-DZD is a network controller and processor IC manufactured by Microchip. It is an ARCNET controller chip designed for embedded control applications using an IEEE 802.3 10baseT or IEEE 802.5 10base5 ARCNET network. It features a fully contained 32-bit 32-bit microcontroller core, an integrated ARCNET controller, and 1 Mb of SRAM. The COM20019I-DZD also supports an onboard 10 MHz oscillator and a 16-bit general-purpose I/O port. It is an ideal solution for creating intelligent, ARCNET-based control solutions for industrial, consumer, and telecom networking applications.
