Universal synchronous/asynchronous receiver transmitter (USART)
The three USART and two UART interfaces are able to communicate at speeds of up to 4
Mbit/s. They support IrDA SIR ENDEC, are ISO 7816 compliant and have LIN Master/Slave
capability. The three USARTs provide hardware management of the CTS and RTS signals.
All USART/UART interfaces can be served by the DMA controller.
Serial peripheral interface (SPI)
Up to three SPIs are able to communicate at up to 16 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.
The SPIs can be served by the DMA controller.
Inter-integrated sound (I
Two standard I2S interfaces (multiplexed with SPI2 and SPI3) are available. They can
operate in master or slave mode, and can be configured to operate with a 16-/32-bit
resolution as input or output channels. Audio sampling frequencies from 8 kHz up to 96 kHz
are supported. When either or both of the I2S interfaces is/are configured in master 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 the
SD Memory Card Specification 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 fully compliant with the CE-ATA digital protocol
Rev1.1.
Universal serial bus (USB)
The STM32L162xD embeds a USB device peripheral compatible with the USB full-speed
12 Mbit/s. The USB interface implements a full-speed (12 Mbit/s) function interface. It has
software-configurable endpoint setting and supports suspend/resume. The dedicated
48 MHz clock is generated from the internal main PLL (the clock source must use a HSE
crystal oscillator).
