Product details
Overview
STM32WB07CCV6TR from STMicroelectronics is an ultra-low-power dual-core wireless SoC integrating an Arm® Cortex®-M0+ MCU (64 MHz, 256 KB Flash, 64 KB SRAM) and a dedicated BlueNRG coprocessor for Bluetooth® Low Energy 5.4 protocol stack execution. It delivers -104 dBm Rx sensitivity at 125 kbps (Long Range), +8 dBm programmable Tx output power, and supports 2 Mbps, 500 kbps, and 125 kbps PHYs - deployed in battery-powered BLE sensors, asset trackers, and medical wearables requiring sub-1 μA Deepstop current.
For engineers reviewing the STM32WB07CCV6TR datasheet, STM32WB07CCV6TR pinout, STM32WB07CCV6TR application, or STM32WB07CCV6TR equivalent, key selection criteria include verified BLE 5.4 feature support (BIS/CIS, LE Power Control, Advertising Extensions), integrated SMPS with 1.2–1.9 V output, hardware AES-128/PKA/RNG security accelerators, and VFQFPN48 package compatibility with IPD matching (MLPF-NRG-01D3).
Technical Context
The device implements a partitioned radio architecture: the BlueNRG coprocessor handles timing-critical BLE link-layer operations (e.g., packet scheduling, radio state transitions) via DMA offload, while the Cortex-M0+ executes host stack layers and application logic. This separation ensures deterministic real-time response without CPU contention.
Its RF subsystem uses a low-IF receiver with automatic gain control and direct-modulation transmitter with linearized LDO-controlled PA biasing. Integrated balun enables single-ended 50 Ω antenna interface, and compliance with ETSI EN 300 328, FCC Part 15, and ARIB STD-T66 is achieved without external filtering when paired with MLPF-NRG-01D3 IPD.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| BLE Version | Bluetooth 5.4 compliant: supports BIS/CIS, LE Power Control, Periodic Advertising Sync Transfer, Encrypted Advertising, and Channel Selection Algorithm #2. |
| Rx Sensitivity | -97 dBm @ 1 Mbps / -104 dBm @ 125 kbps (Long Range): enables robust reception in noisy industrial environments or extended-range sensor deployments. |
| Max Tx Power | +8 dBm (at antenna connector): sufficient for 100+ m line-of-sight range without external PA; programmable in 1 dB steps. |
| Deepstop Current | 0.6 μA @ 1.8 V (with external LSE + BLE wakeup sources): enables >10-year battery life in coin-cell-powered IoT endpoints. |
| CPU Core | Arm Cortex-M0+ @ up to 64 MHz with MPU: delivers 16.5 μA/MHz efficiency and memory protection for certified firmware partitions. |
| Memory | 256 KB Flash (128 × 2 KB pages), 64 KB SRAM (4 banks, configurable retention), 1 KB OTP: supports secure bootloader, field-upgradable firmware, and encrypted key storage. |
| Security Hardware | AES-128 coprocessor, PKA (ECDH acceleration), RNG, CRC unit, 64-bit UID: enables FIPS-compliant key generation and authenticated firmware updates. |
Pinout & Package
VFQFPN48 (6 × 6 mm, 0.4 mm pitch) package with exposed thermal pad (VSS connected to ground plane). Pin functions validated per DS14676 Rev 1 (pages 22–31) and RM0530.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDIO / VDD | Digital I/O supply | 1.7–3.6 V input; powers GPIOs, digital peripherals, and internal regulators - must be decoupled with 100 nF + 1 μF near pin. |
| VSSRF | RF ground reference | Dedicated RF return path; must connect directly to solid ground plane - separate from digital VSS to minimize coupling noise into BLE receiver. |
| ANT | RF antenna interface | Single-ended 50 Ω output; requires external matching network (e.g., MLPF-NRG-01D3 IPD) for regulatory compliance and optimal Tx/Rx performance. |
| PA4–PA11 | Deepstop-capable GPIOs | 8 pins retain output drive capability in Deepstop mode (static high/low, LSE, or RTC output) - used for wake-up signaling or status indication during ultra-low-power operation. |
| OSC_IN / OSC_OUT | 32 MHz crystal oscillator interface | Connects to high-accuracy (±20 ppm) crystal; integrated trimming capacitors eliminate external load caps - critical for BLE timing accuracy and advertising interval stability. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated SMPS regulator | Programmable 1.2–1.9 V output with 4/8 MHz switching frequency - reduces active-mode power by ~30% vs. LDO-only supply at 3.3 V input. |
| Dual-domain power management | VDD12O (always-on 1.0 V) and VDD12I (interruptible 1.2 V) enable selective peripheral shutdown while retaining RTC, BLE wakeup timer, and SRAM0 in Deepstop. |
| Hardware-accelerated BLE timing | BlueNRG coprocessor handles radio state machine, packet timing, and channel hopping - frees Cortex-M0+ for application tasks with <1 μs jitter on connection events. |
| 5 V-tolerant GPIOs | 31 of 32 I/Os tolerate 5 V inputs - simplifies level-shifting in mixed-voltage systems (e.g., interfacing with legacy 5 V sensors or UART peripherals). |
| Secure boot & flash protection | SWD disable, read/write lock bits, and secure bootloader prevent unauthorized firmware access or overwrite - required for medical and industrial certification. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Nordic nRF52840-QIAA | ARM Cortex-M4F core (64 MHz), 1 MB Flash, 256 KB RAM; no integrated SMPS; BLE 5.0 (not 5.4); lacks PKA and hardware BIS/CIS support. | Better floating-point performance for audio processing; higher memory headroom for complex stacks; no native Long Range PHY or LE Power Control. | Select when M4F DSP capability or larger memory is prioritized over BLE 5.4 features and ultra-low-power SMPS efficiency. |
| Texas Instruments CC2652RB | ARM Cortex-M4F + integrated 2.4 GHz RF BAW resonator; BLE 5.0; 352 KB Flash, 80 KB RAM; no hardware PKA or BIS/CIS; uses external DC-DC converter. | Superior RF stability in temperature-varying environments due to BAW; lower Rx sensitivity (-96 dBm @ 1 Mbps); no native Deepstop sub-1 μA mode. | Select for high-temperature industrial deployments where BAW eliminates crystal aging drift, accepting higher active current and missing BLE 5.4 features. |
Compared with nRF52840-QIAA and CC2652RB, STM32WB07CCV6TR uniquely combines BLE 5.4 feature completeness (BIS/CIS, LE Power Control), sub-1 μA Deepstop, integrated SMPS, and hardware PKA/AES - making it optimal for cost-sensitive, long-life, standards-compliant BLE Mesh and wearable designs.

FAQ
What is the maximum BLE advertising packet size supported by STM32WB07CCV6TR?
The device supports Extended Advertising (introduced in BLE 5.0) with up to 1650 bytes per advertising set using the Advertising Data Extension feature. This enables transmission of rich sensor metadata, firmware version strings, or service UUID lists without requiring connection establishment - verified in DS14676 Section 3.6.1 and Bluetooth SIG qualification ID QDID 192422.
Does STM32WB07CCV6TR require an external crystal for BLE radio operation?
Yes - a 32 MHz ±20 ppm fundamental-mode crystal is mandatory for BLE radio timing accuracy and regulatory compliance. The device integrates trimming capacitors, eliminating external load capacitors, but the crystal itself must be externally mounted per layout guidelines in AN5289 and DS14676 Figure 17.
Can the STM32WB07CCV6TR operate as a standalone BLE network processor without running application code on the Cortex-M0+?
Yes - the BlueNRG coprocessor can execute the full BLE stack independently while the Cortex-M0+ remains in deep sleep or reset. Host communication occurs via HCI over UART or SPI, enabling use as a drop-in BLE module replacement with minimal host-side software changes.
What is the recommended companion IPD for STM32WB07CCV6TR in VFQFPN48 package?
The MLPF-NRG-01D3 is the ST-qualified integrated passive device for VFQFPN32/VFQFPN48 packages. It provides impedance matching, harmonic filtering, and ESD protection optimized for the STM32WB07CC's RF front-end - validated per ETSI/FCC radiated emission tests in Application Note AN5289.
