STM32WLE4J8I6

RF Transceiver ICS Overview

The STM32WLE4J8I6 is a Sub-GHz Wireless Microcontroller from the STM32WL series, featuring an Arm Cortex-M4 core operating at up to 48 MHz. It integrates 64 Kbytes of Flash memory and 20 Kbytes of SRAM. The device supports LoRa, (G)FSK, (G)MSK, and BPSK modulations within the 150 MHz to 960 MHz frequency range. Key peripherals include a 12-bit ADC, two ultra-low-power comparators, multiple timers, and standard communication interfaces such as USART, UART, I2C, and SPI.

RF Transceiver ICS Feature Summary

• Integrates a high-performance Arm Cortex-M4 core with DSP instructions and Memory Protection Unit for enhanced security.
• Embeds a low-power LPWAN-compliant radio solution supporting multiple modulation schemes including LoRa and GFSK.
• Includes extensive protection mechanisms for embedded flash memory and SRAM, such as readout and write protection.

RF Transceiver ICS Applications

• Long-range wireless sensor networks
• Smart metering systems
• Industrial IoT monitoring

RF Transceiver ICS Procurement Notes

Verify the specific suffix J8I6 against the official datasheet to confirm package type and temperature grade. Ensure compatibility with required RF regulations in the target deployment region. Cross-reference pin assignments with the UFQFPN-48 or equivalent package documentation before finalizing PCB layout.

RF Transceiver ICS Selection Notes

Select this component when both Sub-GHz long-range capabilities and standard wireless protocols are required on a single chip. The integrated radio reduces external component count compared to separate MCU and transceiver solutions. Evaluate power consumption profiles across different sleep modes to ensure compliance with battery life requirements.

RF Transceiver ICS Part Context

This part belongs to the STM32WL family, designed for multiprotocol System-on-Chip applications. It combines the performance of an Arm Cortex-M4 with a dedicated ARM Cortex-M0+ coprocessor for radio management. The family targets ultra-low-power applications requiring robust connectivity and processing capabilities.
