The STM32F102xx low-density USB access line incorporates the high-performance ARM Cortex™-M3 32-bit RISC core operating at a 48 MHz frequency, high-speed embedded memories (Flash memory of 16 or 32 Kbytes and SRAM of 4 or 6 Kbytes), and an extensive range of enhanced peripherals and I/Os connected to two APB buses. All devices offer standard communication interfaces (one I2C, one SPI, one USB and two USARTs), one 12-bit ADC and two general-purpose 16-bit timers.

The STM32F102xx family operates in the –40 to +85 °C temperature range, from a 2.0 to 3.6 V power supply. A comprehensive set of power-saving mode allows the design of lowpower applications.

The STM32F102xx low-density USB access line is delivered in the LQFP48 7 × 7 mm and LQFP64 10 × 10 mm packages.

The STM32F102xx low-density USB access line microcontrollers are suitable for a wide range of applications:

● Application control and user interface

● Medical and handheld equipment

● PC peripherals, gaming and GPS platforms

● Industrial applications: PLC, inverters, printers, and scanners
