1. The LRW32 long-range wireless and ultra-low-power devices embed a powerful and ultra-low-power radio compliant LPWAN radio solution: LoRa® (only available in STM32WLE5xx), (G)FSK, (G)MSK, and BPSK.
2. 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.
3. The devices also embed several protection mechanisms for embedded Flash memory and SRAM: readout protection, write protection and proprietary code readout protection.
4. 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.
5. 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.
6. 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.
