The 72 MHz clock rate on this Cortex-M3 paired with the 12-bit ADC (16 channels) and motor-control PWM timers gives deterministic timing for a motor-drive or PLC I/O slice. ## Memory sizing — 64 KB Flash, 20 KB RAM The Flash is enough for a bootloader, a Modbus RTU slave, and a few hundred lines of application code. ## Package and assembly The 64-LQFP (10x10 mm) is a standard surface-mount footprint. It reflows on a standard lead-free profile and is compatible with automated optical inspection.","metaTitle":"ST STM32F103R8T6TR ARM Cortex-M3 MCU, 72 MHz, 64 KB Flash","metaDescription":"STMicroelectronics STM32F103R8T6TR 32-bit ARM Cortex-M3 MCU, 72 MHz speed, 64 KB Flash, 20 KB RAM, 64-LQFP, -40 to 85°C.
