This MCU integrates a rich peripheral set: brown-out detect, POR, DMA, I²S, LCD parallel interface, PWM, and a watchdog timer. On the connectivity side it includes CANbus, EBI/EMI, I²C, IrDA, LINbus, MMC/SD, QSPI, SAI, SPI, UART/USART, and USB OTG. The 81-WLCSP (4.04 x 3.95 mm) is the smallest footprint in the STM32F423 family — about 16 mm². That saves board area but demands fine-pitch assembly capability and a good solder-paste stencil. The part is surface-mount only, shipped in Tape & Reel. MSL level is not stated in this record, but WLCSP packages typically run MSL 1 or 3; verify with the pouch floor-life label before reflow. STMicroelectronics lists the STM32F423MHY3TR as Active.","metaTitle":"STM32F423MHY3TR STM32F4 MCU, 100MHz, 1.5MB Flash, 81-WLCSP","metaDescription":"STMicroelectronics STM32F423MHY3TR ARM Cortex-M4 MCU, 100MHz, 1.5MB Flash, 320KB SRAM, -40°C to 125°C.
