STMicroelectronics has announced the first LoRa SoC, Named STM32WLE5 well Designed for the long-range and low-power wide-area networking.
However, the STMicro’s STM32WLE5 is not only the first SoC(System on Chip) to integrate LoRa connectivity. Their first claim comes from the fact that it is the world’s first to place it on a die. Rather than simply integrating on the same main SoC hardware.
The STM32WL comes with an Arm Cortex-M4 processor running at 48MHz with DSP (digital signal processor ) and memory protection unit. It comes with up to 256kB of flash memory and up to 64kB of SRAM.
The radio system supports LoRa modulation alongside (G)FSK, (G)MSK, and BPSK, and works from 150MHz up to 960MHz. With one output running up to 22dBm and the other optimized for power consumption, running at up to 15dBm.
The Semtech SX1262 sub-gigahertz radio thus finds itself closer to the heart of the design. which could potentially spell good news for power draw.
While looking to the security side of the design. It includes AES 128- and 256-bit off acceleration. Fully hardware-level random number generator, a private key accelerator, and a 96-bit ID unique to each chip. Connectivity includes two SPIs, three I2Cs, one ultra-low-power UART, two USART, seven 16- and 32-bit timers. It also comes with One analog to digital (ADC) and digital to analog converters (DAC) at a 12-bit of resolution. The SoC also comes with an onboard temperature sensor and two ULP comparators. Also plus up to 43 general-purpose input/outputs (GPIOs).
