2 Description
The STM32F102xx medium-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 64 or 128 Kbytes and SRAM of 10 or 16 Kbytes),
and an extensive range of enhanced peripherals and I/Os connected to two APB buses. All
devices offer standard communication interfaces (two I
2
Cs, two SPIs, one USB and three
USARTs), one 12-bit ADC and three 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 low-
power applications.
The STM32F102xx medium-density USB access line is delivered in the LQFP48 7 × 7 mm
and LQFP64 10 × 10 mm packages.
The STM32F102xx medium-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
• Alarm systems, Video intercom, and HVAC
