Procurement Notes

Verify the specific suffix 'I7' against the official STMicroelectronics datasheet to confirm pinout, temperature grade, and packaging details. Ensure compatibility with the required frequency band and modulation standards for your target application. Confirm moisture sensitivity handling requirements during storage and assembly processes.

Selection Notes

Select this component when a combined MCU and Sub-GHz radio solution is required for low-power wide-area network deployments. The integration of the Cortex-M4 core simplifies firmware development compared to separate MCU-radio architectures. Evaluate the 256 KB SRAM capacity against application memory requirements before finalizing the selection.

Part Context

This part belongs to the STM32WL family, which combines ARM Cortex-M4 and Cortex-M0+ cores with a Sub-GHz radio. The STM32WLE5JCI7 variant specifically offers 256 KB of SRAM. It is designed for applications requiring long-range communication with minimal power consumption, leveraging patented LoRa technology for robust signal penetration.

Replacement Considerations

Consult the STM32WL product page for alternative pin-to-pin or feature-compatible devices within the same family. Verify that any substitute maintains the required 256 KB SRAM size and Sub-GHz frequency support.
