Description

STM32U545xx

16/283

DS14216 Rev 1

full-speed, and one generic synchronous 8-/16-bit PSSI (parallel data input/output slave

interface).

The devices operate in the –40 to +85 °C (+105 °C junction) and –40 to +125 °C

(+130 °C junction) temperature ranges from a 1.71 to 3.6 V power supply.

A comprehensive set of power-saving modes allow the design of low-power applications.

Many peripherals (including communication, analog, timers and audio peripherals) can be

functional and autonomous down to Stop mode with direct memory access, thanks to

LPBAM support (low-power background autonomous mode).

Some independent power supplies are supported like an analog independent supply input

for ADC, DACs, OPAMPs and comparators, a 3.3 V dedicated supply input for USB and

up to 14 I/Os, that can be supplied independently down to 1.08 V. A VBAT input is available

for connecting a backup battery in order to preserve the RTC functionality and to backup 32

32-bit registers and 2-Kbyte SRAM.

The devices offer eight packages from 48 to 100 pins.
