The LoRa^® modulation is available in STM32WLx5xx only.

These devices are designed to be extremely low-power and are based on the high-performance Arm^® Cortex^®-M4 32-bit RISC core operating at a frequency of up to 48 MHz. This core implements a full set of DSP instructions and an independent memory protection unit (MPU) that enhances the application security.

The devices embed high-speed memories (flash memory up to 256 Kbytes, SRAM up to 64 Kbytes), and an extensive range of enhanced I/Os and peripherals.

The devices also embed several protection mechanisms for embedded flash memory and SRAM: readout protection, write protection and proprietary code readout protection.

These devices offer a 12-bit ADC, a 12-bit DAC low-power sample-and-hold, two ultra-low-power comparators associated with a high-accuracy reference voltage generator.

The devices embed a low-power RTC with a 32-bit sub-second wakeup counter, one 16-bit single-channel timer, two 16-bit four-channel timers (supporting motor control), one 32-bit four-channel timer and three 16-bit ultra-low-power timers.

These devices also embed two DMA controllers (7 channels each) allowing any transfer combination between memory (flash memory, SRAM1 and SRAM2) and peripheral, using the DMAMUX1 for flexible DMA channel mapping.

The devices also feature the following standard and advanced communication interfaces:two USARTs (supporting LIN, smartcard, IrDA, modem control and ISO7816), one low-power UART (LPUART), three I2Cs (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) 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 V_BAT 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 V_DD is not present, through a CR2032-like battery, a supercap or a small rechargeable battery.
