Description

Doc ID 022152 Rev 3

31/180

SysTick timer

This timer is dedicated to real-time operating systems, but could also be used as a standard

downcounter. It features:

●

A 24-bit downcounter

●

Autoreload capability

●

Maskable system interrupt generation when the counter reaches 0

●

Programmable clock source.

2.2.21

Inter-integrated circuit interface (I²C)

Up to three I²C bus interfaces can operate in multimaster and slave modes. They can

support the Standard- and Fast-modes. They support the 7/10-bit addressing mode and the

7-bit dual addressing mode (as slave). A hardware CRC generation/verification is

embedded.

They can be served by DMA and they support SMBus 2.0/PMBus.

2.2.22

Universal synchronous/asynchronous receiver transmitters (USART)

The STM32F405xx and STM32F407xx embed four universal synchronous/asynchronous

receiver transmitters (USART1, USART2, USART3 and USART6) and two universal

asynchronous receiver transmitters (UART4 and UART5).

These six interfaces provide asynchronous communication, IrDA SIR ENDEC support,

multiprocessor communication mode, single-wire half-duplex communication mode and

have LIN Master/Slave capability. The USART1 and USART6 interfaces are able to

communicate at speeds of up to 10.5 Mbit/s. The other available interfaces communicate at

up to 5.25 bit/s.

USART1, USART2, USART3 and USART6 also provide hardware management of the CTS

and RTS signals, Smart Card mode (ISO 7816 compliant) and SPI-like communication

capability. All interfaces can be served by the DMA controller.
