It has 2 MB Flash and 1 MB RAM. The 140 I/O pins in a 176-LQFP package give plenty of GPIO for parallel displays, external memory buses, or sensor arrays. Connectivity covers CANbus, Ethernet, USB OTG, multiple SPI/I²C/UART, and SDIO — so this MCU can act as a central gateway on a factory floor or a smart display controller in an HMI panel. ## Industrial temperature range and environment Internal oscillator and brown-out detect are included.
