Description
STM32WLE5J8I6 is a member of STMicroelectronics’ STM32WLE5 wireless MCU family. It is a single‑chip solution that combines a low‑power Arm Cortex‑M4 MCU with an integrated Sub‑GHz radio transceiver, enabling long‑range IoT at 868/915 MHz using LoRa, FSK, GFSK, or OOK (Semtech SX127x tech).
Key points:
- Ultra‑low power with multiple low‑power modes; operating voltage 1.65–3.6 V; CPU up to ~64 MHz.
- Memory options vary by variant (typical hundreds of KB Flash and tens of KB RAM).
- Security: hardware AES‑128, true RNG, secure boot, and secure firmware updates.
- Peripherals: GPIO, timers, ADC/DAC, UART/SPI/I2C, plus RF front‑end and radio controller.
- Development: supported by STM32CubeWL and CubeMX, LoRaWAN/wireless stacks, with Keil, IAR, and GCC toolchains.
Use cases: battery‑powered IoT nodes, asset tracking, remote sensing, and smart metering where low power, long range, and security matter.
