The internal oscillator keeps the core running without an external crystal — fine for UART and I²C timing at reasonable baud rates, though the internal RC accuracy (typically ±1% after calibration) means you budget margin for the USB-less connectivity set. For dual-sourcing flexibility, the STM32F100 value line includes multiple density and package variants. If a 64-TFBGA footprint is locked, the base product number STM32F100 covers pin-compatible siblings with different Flash/RAM sizes — useful for scaling firmware without a board respin. ## Data converters and connectivity The 24 MHz core speed is modest by today's standards, but for a motor-control loop sampling at 10-20 kHz or a Modbus RTU poll cycle, it leaves headroom for the control algorithm plus a lightweight RTOS.","metaTitle":"STM32F100RBH6B STM32F1 ARM Cortex-M3 MCU, 24 MHz","metaDescription":"STMicroelectronics STM32F100RBH6B 32-bit MCU with ARM Cortex-M3 core at 24 MHz, 128 KB Flash, 8 KB SRAM, 51 I/O, 64-TFBGA.
