Product details
Overview
STM32WB09KEV6TR from STMicroelectronics is an ultra-low-power dual-core wireless SoC integrating an Arm® Cortex®-M0+ MCU (64 MHz) and a Bluetooth® LE 5.4 radio coprocessor with integrated balun, 512 KB flash, 64 KB RAM, and hardware security accelerators (AES-128, PKA, TRNG). It operates from 1.7–3.6 V across –40 °C to +105 °C and supports standalone or network-processor BLE applications in compact VFQFPN32 packaging.
For engineers reviewing the STM32WB09KEV6TR datasheet, STM32WB09KEV6TR pinout, STM32WB09KEV6TR application, or STM32WB09KEV6TR equivalent, key selection criteria include BLE 5.4 feature support (Direction Finding, LE Coded, Isochronous Channels), ultra-low power Deepstop mode (0.9 µA with LSE), RF sensitivity (–104 dBm @ 125 kbit/s), integrated SMPS, and hardware cryptographic acceleration for secure firmware updates and device authentication.
Technical Context
The device implements a partitioned Bluetooth® LE stack: time-critical link-layer operations (e.g., packet timing, encryption, direction finding) are offloaded to a dedicated BlueNRG DMA-based coprocessor, while non-real-time protocol handling (host stack, profiles) runs on the Cortex®-M0+. This separation ensures deterministic RF timing without CPU intervention.
Its RF subsystem uses a low-IF RX architecture with complex I/Q filtering and programmable LDO-controlled TX output (up to +8 dBm), achieving –97 dBm sensitivity at 1 Mbit/s and supporting all BLE 5.4 PHY modes (125/500 kbit/s Coded, 1/2 Mbit/s Uncoded). The integrated balun enables single-ended 50 Ω antenna interface without external matching components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-core BLE SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Nordic nRF52840 DK | ARM Cortex-M4F core, no integrated SMPS, higher active current (4.8 mA TX @ 0 dBm), lacks PKA accelerator | Requires external DC-DC for ultra-low-power designs; limited hardware crypto for high-assurance medical use | Select when floating-point math or USB HID support is required; not suitable for >10-year battery life targets |
| Texas Instruments CC2652RB | Integrated BAW resonator eliminates external crystal; lower TX power (+5 dBm max); no hardware PKA or SMPS | Reduces BOM count for crystal-less designs but lacks cryptographic acceleration for secure key management | Select for cost-sensitive consumer devices where BOM reduction outweighs need for hardware PKA or extended battery life |
Compared with nRF52840 and CC2652RB, STM32WB09KEV6TR uniquely combines integrated SMPS, hardware PKA for ECC, and BLE 5.4 Direction Finding - making it optimal for certified, long-life, secure industrial and medical BLE endpoints requiring minimal external components.

FAQ
What is the maximum supported BLE data rate and PHY configuration?
The STM32WB09KEV6TR supports all Bluetooth® LE 5.4 PHY modes: 125 kbit/s and 500 kbit/s (Coded S=2/S=8), 1 Mbit/s, and 2 Mbit/s (Uncoded). Its RF subsystem achieves –97 dBm sensitivity at 1 Mbit/s and –104 dBm at 125 kbit/s, enabling adaptive data rate selection based on link budget and power constraints.
Does this part require an external crystal for BLE operation?
No. The STM32WB09KEV6TR integrates a 32 MHz crystal oscillator with trimming capacitors and supports BLE timing using its internal HSE oscillator. An external 32 kHz LSE crystal is optional - the device can operate in Deepstop mode using either LSE or internal LSI for RTC and BLE wakeup timing.
How is flash memory protected against unauthorized access?
Flash protection is enforced via hardware read/write lock bits per 2 KB page, SWD debug interface disable, and secure bootloader validation. Once enabled, these protections prevent JTAG/SWD readout and enforce signed firmware image verification before execution - meeting IEC 62443-3-3 SL2 requirements for secure boot.
Can the integrated SMPS be bypassed for simpler power design?
Yes. The SMPS can be disabled by connecting its output directly to VDD, allowing operation using only the internal MLDO regulator. In this configuration, the device draws higher active current but eliminates external inductor/capacitor components - suitable for rapid prototyping or low-volume applications where power efficiency is secondary.
