Communication interfaces
3.15.1
IC bus
Up to two IC 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.
3.15.2
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.
3.15.3
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.
3.15.4
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).
3.16
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.
