STM32F103
Overview
- ARM® 32-bit Cortex®-M3 CPU Core - 72 MHz maximum frequency, 1.25 DMIPS/MHz (Dhrystone 2.1) performance at 0 wait state memory access - Single-cycle multiplication and hardware division
- Memories - 64 or 128 Kbytes of Flash memory - 20 Kbytes of SRAM
- Clock, reset and supply management - 2.0 to 3.6 V application supply and I/Os - POR, PDR, and programmable voltage detector (PVD) - 4-to-16 MHz crystal oscillator - Internal 8 MHz factory-trimmed RC - Internal 40 kHz RC - PLL for CPU clock - 32 kHz oscillator for RTC with calibration
- Low-power - Sleep, Stop and Standby modes - VBAT supply for RTC and backup registers
- 2 x 12-bit, 1 µs A/D converters (up to 16 channels) - Conversion range: 0 to 3.6 V - Dual-sample and hold capability - Temperature sensor
- DMA - 7-channel DMA controller - Peripherals supported: timers, ADC, SPIs, I2Cs and USARTs
- Up to 80 fast I/O ports - 26/37/51/80 I/Os, all mappable on 16 external interrupt vectors and almost all 5 V-tolerant
