The 32 KB erase granularity is the standard STM32F3 sector size, so an OTA update strategy needs to work within that block boundary. ## Analog peripherals and sensor interface The 15-channel 12-bit ADC samples at up to 5 Msps in the STM32F3 family, enough for simultaneous current and voltage sensing in a three-phase motor drive or for multiplexing several analog sensor inputs. The single 12-bit DAC can output a reference voltage or an analog setpoint for an external regulator or amplifier. The internal oscillator is rated for the full temperature range, but for precision timing or a CAN bus you will want an external crystal. The part is ROHS3 compliant. For BOM planning, this MCU is a safe choice for a multi-year production run; no last-time-buy risk is visible. It is a surface-mount package with exposed pad for thermal dissipation. The 51 I/O lines give plenty of headroom for a mixed-signal board with a parallel LCD, keypad matrix, or multiple serial buses.","metaTitle":"STM32F301R6T6 STM32F3 ARM Cortex-M4 MCU, 72 MHz, 64-LQFP","metaDescription":"STM32F301R6T6 32-bit MCU with ARM Cortex-M4 core at 72 MHz, 32 KB Flash, 16 KB SRAM, 15x12-bit ADC, 1x12-bit DAC, -40°C to 85°C.
