The Flash is large enough for a modest RTOS, a communication stack, and application code; the SRAM handles a few hundred bytes of packet buffers and stack. Field reprogrammability is via the built-in bootloader over UART or I²C — no external programmer needed, but the Flash endurance (typically 10k cycles) means frequent OTA updates are not the intended use case.","metaTitle":"ST STM32F101TBU6TR ARM Cortex-M3 MCU, 36 MHz, 128 KB Flash","metaDescription":"STM32F101TBU6TR 32-bit MCU with ARM Cortex-M3 core at 36 MHz, 128 KB Flash, 16 KB RAM, 26 I/O, -40°C to 85°C.
