CAN FD controller with integrated transceiver — one chip, one BOM line
The TCAN4550RGYTQ1 is a CAN FD controller from Texas Instruments that integrates the transceiver on-chip, so a single package replaces the traditional two-chip CAN controller plus external transceiver layout. The AEC-Q100 automotive qualification means it is rated for under-hood and chassis-domain temperature and reliability requirements.
Wettable flank QFN — AOI-friendly, reworkable
The 20-VFQFN package (3.5x4.5 mm body) uses a wettable flank on the side terminals, which lets automated optical inspection confirm solder-joint quality after reflow — a real advantage over standard QFNs where the side terminations are hidden.
