I²C bus
Up to two I²C bus interfaces can operate in multimaster and slave modes. They can support
standard and fast modes.
They support dual slave addressing (7-bit only) and both 7/10-bit addressing in master
mode. A hardware CRC generation/verification is embedded.
They can be served by DMA and they support SM Bus 2.0/PM Bus.
Universal synchronous/asynchronous receiver transmitter (USART)
One of the USART interfaces is able to communicate at speeds of up to 4.5 Mbit/s. The
other available interfaces communicate at up to 2.25 Mbit/s. They provide hardware
management of the CTS and RTS signals, IrDA SIR ENDEC support, are ISO 7816
compliant and have LIN Master/Slave capability.
All USART interfaces can be served by the DMA controller.
Serial peripheral interface (SPI)
Up to two SPIs are able to communicate up to 18 Mbits/s in slave and master modes in full-
duplex and simplex communication modes. The 3-bit prescaler gives 8 master mode
frequencies and the frame is configurable to 8 bits or 16 bits. The hardware CRC
generation/verification supports basic SD Card/MMC modes.
Both SPIs can be served by the DMA controller.
Controller area network (CAN)
The CAN is compliant with specifications 2.0A and B (active) with a bit rate up to 1 Mbit/s. It
can receive and transmit standard frames with 11-bit identifiers as well as extended frames
with 29-bit identifiers. It has three transmit mailboxes, two receive FIFOs with 3 stages and
14 scalable filter banks.
Universal serial bus (USB)
The STM32F103xx performance line embeds a USB device peripheral compatible with the
USB full-speed 12 Mbs. The USB interface implements a full-speed (12 Mbit/s) function
interface. It has software-configurable endpoint setting and suspend/resume support. The
dedicated 48 MHz clock is generated from the internal main PLL (the clock source must use
a HSE crystal oscillator).
A 24-bit downcounter
Autoreload capability
Maskable system interrupt generation when the counter reaches 0
