The 128 KB Flash and 24K x 8 RAM are sized for a single control algorithm plus a modest communications stack — think field-oriented motor control or a multi-sensor data concentrator. ## Three 16-bit sigma-delta ADCs — the analog edge What sets this part apart in the STM32F3 line is the data converter set: one 12-bit SAR ADC and three 16-bit sigma-delta ADCs, plus three 12-bit DACs. The sigma-delta channels are built for high-resolution, low-speed measurements — weigh scales, pressure sensors, or audio-band signal acquisition — without an external ADC. The 12-bit SAR handles faster conversions for overcurrent detection or encoder feedback. ## Industrial temperature grade — -40 to 105 °C The 105 °C ceiling gives margin above the typical 85 °C industrial limit, which matters when the part sits next to a hot power stage or inside a sealed enclosure.","metaTitle":"STM32F373VBT7 STM32F3 ARM Cortex-M4 MCU, 72 MHz","metaDescription":"STM32F373VBT7 32-bit MCU with ARM Cortex-M4 core at 72 MHz, 128 KB Flash, 24K x 8 RAM, three 16-bit sigma-delta ADCs.
