Product details
Overview
STM32WL5MOCH6TR from STMicroelectronics is a certified multiprotocol LPWAN system-in-package (SiP) module integrating dual-core Arm® Cortex®-M4/M0+ MCU, sub-GHz radio transceiver, 256 KB flash, 64 KB SRAM, and embedded 32 MHz TCXO + 32 kHz RTC crystals. It supports LoRa®, (G)FSK, (G)MSK, and BPSK modulation across 864–928 MHz bands with programmable +22 dBm high-power and +15 dBm low-power RF output, targeting battery-powered IoT end-nodes requiring regulatory compliance (ETSI/FCC/ARIB).
For engineers reviewing the STM32WL5MOCH6TR datasheet, STM32WL5MOCH6TR pinout, STM32WL5MOCH6TR application, or STM32WL5MOCH6TR equivalent, this module eliminates RF design complexity while delivering protocol-stack royalty-free operation, integrated SMPS, 37 GPIOs, and hardware-accelerated security (AES-256, PKA, STSAFE-A110 footprint) - critical for secure, ultra-low-power wireless sensor networks and smart utility metering.
Technical Context
The STM32WL5MOCH6TR implements a dual-core architecture where the Cortex-M4 executes real-time protocol stacks (LoRaWAN®, mioty, W-MBus) and application logic, while the Cortex-M0+ handles low-power radio control and peripheral management. Its ART Accelerator enables deterministic 48 MHz execution from flash without wait states.
Radio functionality is fully integrated: matching network, IPD filter, RFO_HP/RFO_LP outputs, RFI_P/RFI_N inputs, BIAS_HP/BIAS_LP control lines, and VR_PA supply are all on-module. The LGA92 package embeds passive SMPS components, eliminating external inductor/capacitor requirements for DC-DC conversion.

Equivalent & Alternatives
The following parts are listed as comparable options for similar multiprotocol LPWAN module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SX1280 + STM32L4 | Discrete RF IC + separate MCU; no integrated TCXO, SMPS, or regulatory certification - requires full RF design and lab testing. | Higher engineering effort for antenna matching, filtering, and EMI mitigation; suitable only for high-volume custom designs. | Select only when absolute bill-of-materials cost optimization outweighs NRE and certification schedule risk. |
| RA4W1 + SX1262 | Renesas MCU lacks dual-core radio offload; SX1262 supports LoRa® but not (G)MSK/BPSK; no embedded STSAFE footprint. | Requires external secure element for key storage; limited to LoRa®/FSK protocols - incompatible with mioty or W-MBus deployments. | Choose only for pure LoRaWAN® gateways where protocol flexibility and hardware security are non-critical. |
Compared with SX1280+STM32L4 and RA4W1+SX1262, the STM32WL5MOCH6TR delivers pre-certified regulatory compliance, dual-core radio co-processing, and integrated security - reducing total development cost by ≥$280k and time-to-revenue by 8 months for certified LPWAN endpoints.

FAQ
What regulatory certifications does STM32WL5MOCH6TR hold?
The STM32WL5MOCH6TR carries full pre-certification under FCC Part 15 (ID: YCP-32WL5MOCH01), ISED Canada (IC: 8976A-32WL5MOCH01), ETSI EN 300 220, and ARIB STD-T108. Certification covers its default 864–928 MHz frequency range, +22 dBm high-power and +15 dBm low-power modes, and specified modulation schemes (LoRa®, (G)FSK). Any deviation requires Class 2 permissive change filing.
How is RF output power configured between high and low modes?
RF output power is selected using the SW_CTL pin and BIAS_HP/BIAS_LP control lines. Driving SW_CTL high activates the RFO_HP path with BIAS_HP asserted, enabling +22 dBm output; driving SW_CTL low selects RFO_LP with BIAS_LP asserted for +15 dBm. External RF switch (e.g., Qorvo QM11035) is required for automatic path selection in dynamic power control applications.
Does STM32WL5MOCH6TR include STSAFE-A110 security IC?
No - the STM32WL5MOCH6TR variant does not integrate STSAFE-A110. It provides only the STSAFE-A110 footprint (PCB pads and routing), allowing optional placement of the secure element. In contrast, the STM32WL5MOCH6S part number includes the STSAFE-A110 pre-soldered. PB8 GPIO controls STSAFE power sequencing when used, supporting 2.6–3.6 V operation or extended 1.8–3.6 V via external switching.
What is the role of the embedded 32 MHz TCXO and 32 kHz RTC crystal?
The 32 MHz TCXO serves as the high-speed clock source (HSE) for the MCU core and radio subsystem, providing ±0.5 ppm stability over –40°C to +85°C - eliminating need for external calibration. The 32 kHz crystal drives the low-speed oscillator (LSE) for the real-time clock and low-power timers, enabling precise wake-up intervals and timestamping with ±20 ppm accuracy without software compensation.
