Product details
Overview
STM32WB5MMGH6TR from STMicroelectronics is a certified 2.4 GHz multiprotocol wireless system-in-package (SiP) module integrating an STM32WB55VGY dual-core Arm® Cortex®-M4F/M0+ MCU, Bluetooth® LE 5.4, IEEE 802.15.4 PHY, integrated chip antenna, and full RF front-end-including matching IPD, LSE/HSE crystals, and SMPS. It delivers +6 dBm TX output, -96 dBm RX sensitivity (BLE 1 Mbps), 1-Mbyte flash, 256-Kbyte SRAM, and operates from 1.71–3.6 V across -40°C to +85°C for battery-powered IoT edge nodes.
For engineers reviewing the STM32WB5MMGH6TR datasheet, STM32WB5MMGH6TR pinout, STM32WB5MMGH6TR application, or STM32WB5MMGH6TR equivalent, this module eliminates RF design complexity while enabling concurrent BLE/Zigbee/OpenThread operation on a single ultra-low-power SiP-ideal for rapid certification-compliant development of beacons, smart locks, and personal health trackers.
Technical Context
The module implements a dual-CPU architecture: the Cortex-M4F (64 MHz, FPU, ART accelerator) handles application firmware and protocol stacks, while the dedicated Cortex-M0+ executes radio firmware and security services-including secure boot, PKA, AES-256, TRNG, and PCROP. This hardware-enforced separation ensures deterministic real-time radio timing and robust firmware isolation.
RF operation is fully self-contained: integrated 32 MHz HSE and 32.774 kHz LSE crystals, on-die SMPS with bypass mode, IPD-based antenna matching, and fixed ANT_IN/RF_OUT pins tied to GND. No external RF components or tuning are required-only DC power and digital I/O connections.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Wireless Protocols | Bluetooth® LE 5.4, Zigbee® 3.0, OpenThread, IEEE 802.15.4-2011 MAC/PHY-enables single-hardware support for multiple certified mesh and point-to-point topologies. |
| RF Performance | +6 dBm TX output power and -96 dBm RX sensitivity (BLE 1 Mbps) deliver up to 75 m range in open-air-sufficient for room-scale indoor IoT without external PA/LNA. |
| CPU Architecture | Dual-core: Cortex-M4F @ 64 MHz (application + stack) + Cortex-M0+ @ 32 MHz (radio & security)-enables true concurrent protocol operation without software arbitration. |
| Memory | 1-Mbyte on-chip flash (with PCROP for secure code partitioning) and 256-Kbyte SRAM-supports full BLE + Zigbee stacks plus user application in a single die. |
| Power Supply | 1.71–3.6 V operation with integrated SMPS-reduces external BOM count and enables direct coin-cell (CR2032) or energy-harvesting supply without discrete DC/DC. |
| Operating Temperature | -40°C to +85°C industrial grade-validated for deployment in uncontrolled environments including HVAC systems, smart lighting, and wearable medical sensors. |
| Package | SiP-LGA86 (7.3 × 11 × 1.382 mm, 0.45 mm pitch)-integrates MCU, crystals, passive SMPS components, IPD, and chip antenna into one surface-mountable unit. |
Pinout & Package
STM32WB5MMGH6TR uses an 86-pin SiP-LGA86 package (7.3 mm × 11 mm × 1.382 mm, 0.45 mm pitch) with integrated antenna on the shorter unshielded side. All RF components-including 32 MHz HSE, 32.774 kHz LSE, SMPS passives, and IPD-are embedded within the module. ANT_IN and RF_OUT pins must be connected to GND; ANT_NC is a mechanical soldering aid only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD / VSS | Power supply rails | 8× VDD and 12× VSS balls provide low-impedance power distribution-critical for RF stability and low-noise analog operation. |
| ANT_IN / RF_OUT | RF interface terminals | Internally connected to integrated chip antenna; must be externally tied to GND-no external antenna option or RF trace routing permitted. |
| PA0–PA15, PB0–PB15, etc. | GPIO / peripheral signals | 68 accessible I/Os mapped to standard STM32WB55 peripherals-including USB FS, SAI, LCD, touch sensing, and crypto accelerators. |
| PH3-BOOT0 | Boot mode selection | Internal pull-down enables flash boot by default; optional external pull-up allows system memory boot for recovery or DFU. |
| NRST | Reset input | Asynchronous active-low reset with internal pull-up-requires only external 100 nF capacitor per datasheet Figure 3 for noise filtering. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated RF Front-End | On-module IPD, crystals, and antenna eliminate RF layout expertise-reducing time-to-certification by >6 months versus discrete RF + MCU designs. |
| Dual-Core Security Isolation | Cortex-M0+ executes radio stack and cryptographic services (AES-256, PKA, TRNG) in hardware-isolated memory-preventing stack-level attacks on BLE/Zigbee keys. |
| Protocol Stack Royalty-Free | ST-provided BLE 5.4 and 802.15.4 stacks require no license fees-enabling cost-sensitive volume production without recurring royalty obligations. |
| Two-Layer PCB Compatibility | Full functionality achievable using only outer pad ring-enables low-cost manufacturing without mandatory 4-layer board requirement. |
| Ultra-Low-Power Operation | SMPS + multiple low-power modes (Stop2, Shutdown) extend CR2032 battery life to >5 years in beacon applications with periodic advertising. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar multiprotocol wireless module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Nordic nRF52840 DK | Discrete MCU + external antenna; requires RF layout, crystal selection, and external DC/DC; no integrated 802.15.4 PHY or Zigbee stack. | Requires full RF validation and protocol stack integration-adds 8–12 weeks to certification timeline. | Select when maximum GPIO flexibility and custom RF tuning are needed; not suitable for rapid-certified product launch. |
| Silicon Labs EFR32MG21A020F768IM32 | Single-core ARM Cortex-M33; proprietary Simplicity Studio stack; no native BLE 5.4 or OpenThread certification; larger QFN48 package. | Limited to Zigbee/Thread-only deployments; lacks concurrent BLE operation and integrated antenna. | Select for Thread-only mesh networks where BLE provisioning is handled by companion device-not for unified BLE/Zigbee endpoints. |
Compared with Nordic nRF52840 DK and EFR32MG21, STM32WB5MMGH6TR uniquely delivers pre-certified concurrent BLE/Zigbee/OpenThread operation in a single SiP with zero RF component count-reducing BOM cost by ~35% and eliminating RF design risk for time-constrained IoT programs.

FAQ
Does STM32WB5MMGH6TR support external antenna connection?
No. The module integrates a monopole chip antenna on its shorter unshielded edge. ANT_IN and RF_OUT pins are internally routed to this antenna and must be externally connected to GND-no external antenna port or RF connector is provided or supported.
What is the role of the Cortex-M0+ core in this module?
The Cortex-M0+ core exclusively executes the radio firmware (BLE/Zigbee/802.15.4 link layers) and security services (AES-256, PKA, TRNG, secure boot). It operates independently from the Cortex-M4F application core, enabling deterministic real-time radio timing and hardware-enforced isolation of cryptographic keys.
Is the 32.774 kHz LSE crystal user-configurable?
No. The LSE crystal is fully integrated and factory-tuned. The module requires LSE to operate in medium-high driving capability (RCC_BDCR_LSEDRV = 10), and users must not modify RCC_HSECR register settings-the HSE is auto-tuned and locked to preserve RF calibration integrity.
Can STM32WB5MMGH6TR operate on a two-layer PCB?
Yes. Using only the outer ring of pads (as defined in Figure 11 of DS13252), full functionality-including USB, all GPIOs, and RF performance-is maintained on a two-layer board. Four-layer routing is optional and recommended only for high-density layouts or stringent EMI requirements.
