STM32F103R8T6 Microcontroller: 72MHz,64-LQFP, Pinout and Features

The STM32F103R8T6 incorporates the high-performance Arm®Cortex®-M0 32-bit RISC core operating at up to 48 MHz frequency, high-speed embedded memories (up to 128 Kbytes of Flash memory and 16 Kbytes of SRAM), and an extensive range of enhanced peripherals and I/Os. All devices offer standard communication interfaces (two I2Cs, two SPI/I2S, one HDMI CEC, and four USARTs), one USB Full-speed device (crystal-less), one CAN, one 12-bit ADC, one 12-bit DAC with two channels, seven 16-bit timers, one 32-bit timer, and an advanced-control PWM timer.

The STM32F103R8T6 operates in the -40 to +85 °C and -40 to +105 °C temperature ranges, from a 2.0 to 3.6 V power supply. A comprehensive set of power-saving modes allows the design of low-power applications.

The STM32F103R8T6 includes devices in seven different packages ranging from 48 pins to 100 pins with a dying form also available upon request. Depending on the device chosen, different sets of peripherals are included.

These features make the STM32F103R8T6 suitable for a wide range of applications such as application control and user interfaces, hand-held equipment, A/V receivers, digital TV, PC peripherals, gaming and GPS platforms, industrial applications, PLCs, inverters, printers, scanners, alarm systems, video intercoms, and HVACs.
