Communication interfaces
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- and 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)
All USART interfaces are able to communicate at speeds of up to 4 Mbit/s. They provide
hardware management of the CTS and RTS signals. They support IrDA SIR ENDEC, 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 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.
Both SPIs can be served by the DMA controller.
Universal serial bus (USB)
The STM32L15xxx 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).
CRC (cyclic redundancy check) calculation unit
The CRC (cyclic redundancy check) calculation unit is used to get a CRC code from a 32-bit
data word and a fixed generator polynomial.
Among other applications, CRC-based techniques are used to verify data transmission or
storage integrity. In the scope of the EN/IEC 60335-1 standard, they offer a means of
verifying the Flash memory integrity. The CRC calculation unit helps compute a signature of
the software during runtime, to be compared with a reference signature generated at link-
time and stored at a given memory location.
