37 Low-power universal asynchronous receiver
transmitter (LPUART)
37.1 Introduction
The low-power universal asynchronous receiver transmitted (LPUART) is an UART which
allows full-duplex UART communications with a limited power consumption. Only
32.768 kHz LSE clock is required to allow UART communications up to 9600 baud/s. Higher
baud rates can be reached when the LPUART is clocked by clock sources different from the
LSE clock.
Even when the microcontroller is in Stop mode, the LPUART can wait for an incoming UART
frame while having an extremely low energy consumption. The LPUART includes all
necessary hardware support to make asynchronous serial communications possible with
minimum power consumption.
It supports half-duplex single wire communications and modem operations (CTS/RTS).
It also supports multiprocessor communications.
DMA (direct memory access) can be used for data transmission/reception.
