All dissipation goes through the leads. ROHS3 compliant. It is not AEC-Q100 qualified, so it is not the pick for under-hood automotive, but it handles the typical industrial environment without derating concerns.","metaTitle":"STM32F401RBT6 STM32F4 ARM Cortex-M4 MCU, 84 MHz, 128KB Flash","metaDescription":"STM32F401RBT6 32-bit ARM Cortex-M4 MCU at 84 MHz with 128KB Flash, 64KB SRAM, USB OTG, 50 I/O, 64-LQFP.
