STM32WLE5J8I6

STM32WLE5J8I6 is STMicroelectronics’ STM32WLE wireless MCU. It combines an ARM Cortex‑M core with an on‑chip wireless transceiver for ultra‑low‑power IoT applications. The device enables secure wireless connectivity in ISM bands (typical options around 868/915 MHz; exact bands depend on the variant) and supports wireless stacks via STM32CubeWL. It includes hardware cryptography and secure boot to protect communications and firmware. The MCU provides a rich peripheral set (GPIOs, timers, ADC/DAC, serial interfaces) and multiple power modes to maximize battery life. Development is supported by ST tools such as STM32CubeMX/STM32CubeWL, STM32CubeIDE, and standard IDEs (Keil, IAR) with middleware for wireless stacks. Suitable uses include remote sensing, smart metering, asset tracking, and building automation. For precise specs (core frequency, RAM/Flash, package, temp range, radio band options), consult the official datasheet and reference manual for this exact suffix (WLE5J8I6).
