Description
STM32WLE5/E4xx
12/145
DS13105 Rev 8
The devices also feature the standard and advanced communication interfaces listed below:
•
two USART (supporting LIN, smartcard, IrDA, modem control and ISO7816)
•
one low-power UART (LPUART)
•
three I2C (SMBus/PMBus)
•
two SPIs (up to 16 MHz, one supporting I2S)
•
semaphores for processor firmware process synchronization
The operating temperature/voltage ranges are –40 °C to +105 °C (+85 °C with radio)(a) from
a 1.8 V to 3.6 V power supply. A comprehensive set of power-saving modes allows the
design of low-power applications.
The devices integrate a high-efficiency SMPS step-down converter and independent power
supplies for ADC, DAC and comparator analog inputs.
A VBAT dedicated supply allows the LSE 32.768 kHz oscillator, the RTC and the backup
registers to be backed up. The devices can maintain these functions even if the main VDD is
not present, through a CR2032-like battery, a supercap or a small rechargeable battery.
a. Devices with suffix 6 operate up to 85 °C. Devices with suffix 7 can operate up to 105 °C except radio.
