72 MHz Cortex-M3 with peripheral set for motor control and industrial comms
The STM32F103RBT7: It integrates a rich peripheral set including DMA, motor control PWM, multiple watchdog timers, a temperature sensor, and connectivity for CAN, I2C, IrDA, LIN, SPI, UART/USART, and USB.
The internal oscillator and POR/PVD blocks reduce external BOM count in space-constrained designs.
64-LQFP footprint and I/O count — board-level fit
The STM32F1 series remains a mainstream offering from ST, with ongoing manufacturing and distributor support. No last-time-buy window to track.
