The peripheral list includes DMA, motor-control PWM, a temp sensor, and a full set of connectivity: CAN, I2C, SPI, UART/USART, USB, IrDA, and LIN. Data converters cover 21 analog inputs at 12-bit resolution and two 12-bit DAC outputs — enough for multi-channel sensor acquisition without an external ADC. ## Supply rails and power-up sequence The built-in POR/PDR/PVD circuits handle power-up sequencing without an external supervisor — the MCU holds reset until the supply is stable. Internal oscillator is available, though for CAN or USB operation an external crystal is recommended for tighter timing.","metaTitle":"STM32F103ZET7 STM32F1 ARM Cortex-M3 MCU, 72 MHz","metaDescription":"STM32F103ZET7 32-bit ARM Cortex-M3 MCU from STMicroelectronics, 72 MHz core, 512 KB Flash, 64 KB RAM, 112 I/O, 144-LQFP.
