Serial peripheral interface (SPI)
Up to three 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.
All SPIs can be served by the DMA controller.
Inter-integrated sound (I
Two standard I
operated in master or slave mode. These interfaces can be configured to operate with 16/32
bit resolution, as input or output channels. Audio sampling frequencies from 8 kHz up to
48 kHz are supported. When either or both of the I
mode, the master clock can be output to the external DAC/CODEC at 256 times the
sampling frequency.
SDIO
An SD/SDIO/MMC host interface is available, that supports MultiMediaCard System
Specification Version 4.2 in three different databus modes: 1-bit (default), 4-bit and 8-bit.
The interface allows data transfer at up to 48 MHz in 8-bit mode, and is compliant with SD
Memory Card Specifications Version 2.0.
The SDIO Card Specification Version 2.0 is also supported with two different databus
modes: 1-bit (default) and 4-bit.
The current version supports only one SD/SDIO/MMC4.2 card at any one time and a stack
of MMC4.1 or previous.
In addition to SD/SDIO/MMC, this interface is also fully compliant with the CE-ATA digital
protocol Rev1.1.
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 STM32F103xF and STM32F103xG performance line embed 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).
GPIOs (general-purpose inputs/outputs)
Each of the GPIO pins can be configured by software as output (push-pull or open-drain), as
input (with or without pull-up or pull-down) or as peripheral alternate function. Most of the
GPIO pins are shared with digital or analog alternate functions. All GPIOs are high current-
capable.
