This part is designed for a dedicated 1.8V rail — common in battery-backed or low-voltage sensor nodes — and will not tolerate a 3.3V supply. If your existing BOM runs on 3.3V, this is the wrong drop-in; look at the STM32F303 or STM32F378 series instead. The internal oscillator and POR circuitry are optimised for this voltage window, so an external regulator with tight tolerance is recommended. The four 12-bit ADCs and two 12-bit DACs give it enough analog front-end capability to handle current sensing and analogue output in a single chip. The 86 I/O count in a 100-LQFP leaves most pins available after allocating the usual power and oscillator connections. The 100-LQFP package is surface-mount and standard for reflow assembly;. For production planning, the ROHS3 compliance is confirmed.","metaTitle":"STM32F358VCT6 STM32F3 ARM Cortex-M4F MCU, 72MHz, 256KB Flash","metaDescription":"STM32F358VCT6 32-bit MCU with ARM Cortex-M4F at 72MHz, 256KB Flash, 8K x 8 RAM, 86 I/O, 1.65V-1.95V supply, -40°C to 85°C.
