The 0.5 mm pitch on the 48-LQFP body means the outer rows break out cleanly on a two-layer board, but the inner power and ground pads benefit from a four-layer stack for a solid return plane — the 65 mA supply current includes the internal PHY, and the switching edges on the parallel host interface create enough di/dt to need a low-inductance ground path. The host interface is parallel — the controller maps its 2Kx8 shared RAM into the host's memory space as a mailbox. No SPI or I²C translation; the host reads and writes frames directly. The ARCNET token-passing protocol handles the network timing, so the host software only manages the buffer pointers. ROHS3 compliant per. ## Lifecycle — active, no NRND flag, no LTB notice The product status is Active. No end-of-life notice, no last-time-buy window, no NRND flag. This is still a valid BOM line for new builds and existing production — no need to stockpile or qualify a replacement yet.","metaTitle":"Microchip COM20022I-HT ARCNET Controller, 48-TQFP, Active","metaDescription":"COM20022I-HT ARCNET 878.1 controller, 48-TQFP (7x7), 4.5-5.5V, 65mA, -40 to +85°C.
