# STM32WLE5JCI6 (Component)
## Description
Multiprotocol LPWAN 32-bit Arm Cortex-M4 MCUs, LoRa, (G)FSK, (G)MSK, BPSK, up to 256KB flash, 64KB SRAM
IC RF TxRx + MCU 802.15.4 LoRa™ 150MHz ~ 960MHz 73-UFBGA
The STM32WLE5JCI6 is an ultra-low-power wireless System-on-Chip (SoC) from STMicroelectronics that combines a 32-bit Arm Cortex-M4 microcontroller with an integrated sub-GHz radio transceiver. It is designed for long-range, low-power IoT and LPWAN applications such as smart metering, smart cities, industrial sensors, and remote monitoring systems.
It supports multiple modulation schemes including LoRa®, (G)FSK, (G)MSK, and BPSK, making it flexible for both proprietary and standardized wireless protocols like LoRaWAN®. The device integrates RF, analog, digital, and security features into a single chip to reduce external components and PCB size.
