The motor-control PWM timer and DMA controller offload the core for closed-loop drive algorithms. Two 12-bit DACs and a 21-channel 12-bit ADC handle analog feedback from current-sense resistors or thermistors.","metaTitle":"ST STM32F103ZCT7TR ARM Cortex-M3 MCU, 72MHz, 256KB Flash","metaDescription":"STMicroelectronics STM32F103ZCT7TR 32-bit MCU: ARM Cortex-M3 at 72MHz, 256KB Flash, 48KB RAM, 112 I/O, -40 to 105°C.
