The peripheral list includes CANbus, USB (device/OTG), QSPI for external Flash or RAM, SAI for audio codecs, multiple I²C and SPI ports, and UART/USART with IrDA and LIN support. The MMC/SD interface lets you log data directly to a microSD card without a separate controller. The integrated 12-bit ADC has 16 multiplexed channels; the single 12-bit DAC covers one analog output. Internal oscillator is on-chip, so you can save two pins and a crystal if the application tolerates the internal RC accuracy. ## Package and temperature grade — board-fit details The CT (Cut Tape) option is also listed for prototype quantities. No last-time-buy notice is in effect, and the part is still in regular production.
