Product details
Overview
STM32WB1MMCH6TR from STMicroelectronics is a certified Bluetooth® Low Energy 5.4 wireless module based on the STM32WB15CCY SoC, integrating dual Arm® Cortex®-M4 (64 MHz, FPU) and Cortex®-M0+ (radio/security) cores, 320 KB flash, 48 KB SRAM, integrated chip antenna, SMPS, and full RF front-end including IPD and matched crystals. It delivers +5.5 dBm TX power and –96 dBm RX sensitivity at 1 Mbps for battery-powered beacons and personal health trackers.
For engineers reviewing the STM32WB1MMCH6TR datasheet, STM32WB1MMCH6TR pinout, STM32WB1MMCH6TR application, or STM32WB1MMCH6TR equivalent, this module eliminates RF design complexity with pre-certified operation (FCC, CE, ISED, KC, SRRC), built-in security (AES-256, PKA, RNG, PCROP), and ultra-low-power modes enabling multi-year coin-cell operation in industrial sensor nodes and wellness wearables.
Technical Context
The module implements a dual-core architecture where the Cortex®-M4 handles application firmware and protocol stack execution while the dedicated Cortex®-M0+ offloads BLE 5.4 radio timing, packet handling, and cryptographic acceleration - enabling deterministic real-time RF behavior without M4 core interruption. The integrated SMPS operates at fixed 4 MHz with passive components embedded, eliminating external DC-DC design effort.
RF performance is stabilized by fully integrated 32 MHz HSE and 32.768 kHz LSE crystals, factory-tuned HSE (RCC_HSECR.HSETUNE auto-loaded), and an on-die IPD providing harmonic rejection and antenna impedance matching. Internal antenna radiation patterns are validated across 2402–2480 MHz per regulatory test reports, with ANT_IN/ANT_OUT pins supporting external antenna routing under new certification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Wireless Standard | Bluetooth® Low Energy 5.4 certified - supports 2 Mbps PHY, advertising extensions, and secure connections out-of-box. |
| RF Performance | +5.5 dBm TX output power and –96 dBm RX sensitivity at 1 Mbps - enables robust link budget for >50 m indoor range with internal antenna. |
| Core Architecture | Dual-core: Cortex®-M4 @ 64 MHz (FPU, ART accelerator) + Cortex®-M0+ @ 32 MHz - separates application logic from time-critical radio tasks. |
| Memory | 320 KB flash (with PCROP protection) and 48 KB SRAM - sufficient for BLE stack + custom application with secure firmware installation (SFI). |
| Power Supply | 1.71–3.6 V operation with integrated SMPS - reduces external BOM count and supports direct Li-ion or coin-cell input without discrete regulator. |
| Security Features | AES-256, PKA (elliptic curve), RNG, 96-bit UID, 48-bit UEI derivation, and 1 KB OTP - enables secure boot, key provisioning, and device identity binding. |
| Regulatory Certifications | FCC ID YCP-32WB1MMCH01, IC ID 8976A-32WB1MMCH01, CE RED, KC, SRRC CMIIT ID 24J31B9F8878, NCC CCAN24Y10600T7 - valid only with internal antenna configuration. |
Pinout & Package
The STM32WB1MMCH6TR is housed in a 10 × 6.5 mm SiP-LGA77 package (B0HQ) with 0.45/0.50 mm pitch, integrating MCU die, crystals, SMPS passives, IPD, and chip antenna - requiring no external RF matching components.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ANT_IN (Pin 6) | Internal antenna enable | Must be connected to ANT_OUT (Pin 7) for internal antenna use; shorting to GND enables external antenna path. |
| ANT_OUT (Pin 7) | Antenna interface | RF output node routed to integrated chip antenna; when used externally, connects to matching network and antenna feed point. |
| VDDSMPS / VSSSMPS (Pins 20/21) | SMPS power terminals | Integrated switch-mode power supply inputs - require external 100 nF decoupling capacitors placed adjacent to pads per layout guidelines. |
| PA0–PA14, PB0–PB8 (Pins 9–14, 22–42, 48–50, etc.) | GPIO / peripheral signals | 27 user-accessible GPIOs mapped from STM32WB15CCY; PB0/PB1/PB2 are RF-sensitive and require <2.7 pF local filtering if used. |
| NRST (Pin 23) | Reset control | Active-low reset input compatible with standard SWD/JTAG debug interfaces and system-level reset sequencing. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-core asymmetric processing | Enables concurrent BLE stack execution (M0+) and rich application logic (M4) without scheduling conflicts or latency spikes. |
| Pre-certified RF subsystem | Eliminates need for RF chamber testing, FCC/CE lab validation, and antenna tuning - cuts time-to-market by ≥6 months. |
| Integrated SMPS with fixed 4 MHz operation | Reduces external component count by 8+ parts (inductor, diode, caps) and improves efficiency over LDO-based solutions at >10 mA loads. |
| On-die IPD for antenna matching | Provides stable 50 Ω impedance across temperature and voltage, maintaining consistent radiation efficiency without PCB-level tuning. |
| Secure firmware installation (SFI) | Allows authenticated, encrypted over-the-air (OTA) updates of BLE radio stack without exposing keys or compromising device identity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar BLE wireless module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| nRF52840 DK | Discrete dev kit (not module); requires external RF matching, crystal, and certification effort - lacks integrated SMPS and IPD. | Targeted at prototyping and evaluation only; not production-ready for certified designs without additional RF validation. | Select only for early-stage development where full RF control is needed; not suitable for volume manufacturing without added compliance cost. |
| DA1469x Module (Dialog/Infineon) | Single-core ARM Cortex-M33; no dual-core separation; lower TX power (+4 dBm); no integrated SMPS - requires external DC-DC. | Optimized for audio streaming (BLE Audio) but lacks BLE 5.4 advertising extensions and secure firmware installation (SFI) capability. | Prefer for voice-enabled accessories; avoid when dual-core isolation, SFI, or +5.5 dBm range is required. |
Compared with nRF52840 DK and DA1469x Module, STM32WB1MMCH6TR uniquely combines pre-certified RF, dual-core deterministic timing, integrated SMPS, and SFI - delivering shortest time-to-certification and lowest BOM cost for production BLE endpoints.

FAQ
What certifications apply to the STM32WB1MMCH6TR, and are they valid for external antenna use?
The module holds FCC ID YCP-32WB1MMCH01, IC ID 8976A-32WB1MMCH01, CE RED, KC, SRRC CMIIT ID 24J31B9F8878, and NCC CCAN24Y10600T7 - all obtained using the internal chip antenna. Regulatory approvals do not extend to external antenna configurations; integrators must perform new certification testing if ANT_IN is grounded and ANT_OUT connected to an external RF path.
Can the integrated SMPS be disabled or reconfigured for different switching frequencies?
No - the SMPS is hardwired to operate at a fixed 4 MHz frequency with passive components permanently embedded in the SiP. Its configuration is non-adjustable; users cannot change switching frequency, disable the SMPS, or substitute it with an external regulator without violating the module's certified electrical characteristics and thermal profile.
How does the dual-core architecture improve BLE reliability compared to single-core alternatives?
The Cortex®-M0+ exclusively manages BLE radio timing, packet assembly, and cryptographic operations in hardware-synchronized cycles, isolating them from M4 application interrupts. This prevents stack corruption or missed advertising events during heavy CPU load - ensuring deterministic BLE behavior even under sustained 64 MHz M4 execution, unlike single-core implementations where radio tasks compete for CPU cycles.
Which GPIOs require special layout treatment, and why?
PB0, PB1, and PB2 are designated as RF-sensitive GPIOs due to proximity to the RF transceiver block. If used, they must be routed with minimal trace length (<5 mm), surrounded by ground pour, and terminated with a 2.7 pF capacitor placed within 1 mm of the pin - otherwise, they act as parasitic antennas that degrade radiated emissions and reduce RX sensitivity by up to 3 dB.
