The part stands out for its data converter array: a 12-bit ADC, three 16-bit ADCs, and three 12-bit DACs — a mix that suits multi-channel sensor conditioning and analog output generation without external converters. ## What the 72 MHz core and 128 KB Flash mean for the BOM The 72 MHz Cortex-M4 delivers enough throughput for one or two control loops with floating-point math, plus communication stack overhead. The 128 KB Flash is the mid-density tier in the STM32F373 family — enough for a Modbus or CANopen node with a modest application layer, but tight if you plan a full USB host stack or heavy data logging. The 24K x 8 RAM handles typical buffer and variable space; watch the stack depth if you run multiple interrupt-heavy peripherals. ## Lifecycle: end-of-life — plan your last-time buy The STM32F373CBT6 carries an end-of-life (EOL) lifecycle stage. Official production status is active, but the EOL flag means a last-time-buy window is open or imminent. ## Where it fits: industrial control and instrumentation ## Sourcing reality Given the EOL lifecycle, early engagement on volume and lead time is recommended.","metaTitle":"ST STM32F373CBT6 ARM Cortex-M4 MCU, 72MHz, 128KB Flash","metaDescription":"STM32F373CBT6 32-bit ARM Cortex-M4 MCU from STMicroelectronics. 72MHz core, 128KB Flash, 24K x 8 RAM, 48-LQFP, -40°C to 85°C.
