Product details
Overview
SPBTLE-RF0 from STMicroelectronics is a certified Bluetooth® Low Energy v4.1 network processor module integrating the BlueNRG-MS radio controller, embedded full-stack firmware (GAP/GATT/SM/L2CAP/LL/RFPHY), +4 dBm transmit power, -88 dBm receive sensitivity, and on-board chip antenna in a 13.5 × 11.5 × 2 mm LGA package. It enables simultaneous master/slave operation for wearable sensors and battery-powered peripherals.
For engineers reviewing the SPBTLE-RF0 datasheet, SPBTLE-RF0 pinout, SPBTLE-RF0 application, or SPBTLE-RF0 equivalent, key selection criteria include SPI-host interface compatibility, ultra-low standby current (1.98 µA), dual-role concurrency support, and FCC/IC/CE modular certification status - all critical for rapid integration into coin-cell-powered consumer medical and industrial edge devices.
Technical Context
The SPBTLE-RF0 implements a complete Bluetooth LE protocol stack in ROM/Flash, offloading host MCU processing via standardized SPI-based ACI (Application Controller Interface). Its BlueNRG-MS core supports concurrent advertising and scanning, privacy v1.1, LE Ping, and L2CAP connection-oriented channels.
Hardware integration includes a 32 MHz crystal oscillator, internal 32.768 kHz ring oscillator, integrated LDO, RF balun, and matching network - all co-located with the chip antenna to deliver a pre-certified 2.402–2.480 GHz transceiver subsystem requiring no external RF tuning or regulatory retesting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bluetooth Version | v4.1 compliant - supports directed advertising, connection parameter requests, and 32-bit UUIDs without host stack modification. |
| Transmit Power | +4 dBm - sufficient for 10+ meter line-of-sight range with coin-cell power budget (e.g., CR2032). |
| Receive Sensitivity | -88 dBm - enables robust link establishment in noisy 2.4 GHz environments (Wi-Fi, microwave leakage). |
| Link Budget | 92 dB - calculated from Tx/Rx specs; ensures reliable communication in low-SNR industrial settings. |
| Standby Current | 1.98 µA - extends AAA/coin-cell life to multi-year operation in intermittently active sensors. |
| Supply Voltage | 1.7–3.6 V - directly compatible with single 3 V coin cells or two AAA batteries without regulation. |
| Operating Temp | -40 °C to +85 °C - validated for deployment in outdoor wearables and uncontrolled industrial enclosures. |
Pinout & Package
SPBTLE-RF0 uses an 11-pin LGA (Land Grid Array) package measuring 13.5 × 11.5 × 2.0 mm, optimized for compact PCB layouts and automated reflow assembly (JEDEC J-STD-020 Class 3 profile). All pins are surface-mount, with GND pins requiring low-inductance grounding per RF layout guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Vin (Pin 5) | Power input | Accepts 1.7–3.6 V DC; powers internal LDO and RF circuitry - no external regulator needed. |
| GND (Pin 6) | Ground reference | Mandatory low-impedance connection to system ground plane; multiple GND pins must be tied together. |
| SPI_IRQ (Pin 4) | Interrupt output | Active-high signal indicating pending data or event from module to host MCU - triggers SPI read sequence. |
| SPI_CLK (Pin 7) | Clock input | Host-generated SPI clock up to 8 MHz - synchronizes all ACI command/response transfers. |
| SPI_MISO (Pin 8) | Data output | Master-in/slave-out line carrying module responses and asynchronous event notifications. |
| SPI_MOSI (Pin 9) | Data input | Master-out/slave-in line delivering ACI commands, configuration parameters, and firmware updates. |
| SPI_CS (Pin 10) | Chip select | Active-low enable signal - asserts SPI transaction window and prevents bus contention. |
| BT_RESET (Pin 11) | Reset input | Active-low asynchronous reset; must remain low until Vin stabilizes to prevent boot failure. |
Key Features
| Feature | Design Value |
|---|---|
| Embedded BLE Stack | Full GAP/GATT/SM/L2CAP/LL/RFPHY stack in ROM - eliminates host MCU memory overhead and BLE stack licensing. |
| On-Field Firmware Upgrade | SPI-based field-upgradable stack via prebuilt .dat files - enables security patching and feature updates without hardware change. |
| AES Security Co-Processor | Hardware-accelerated AES-128 encryption - offloads pairing, bonding, and encrypted attribute access from host CPU. |
| Modular Certification | FCC ID S9NSPBTLERF, IC 8976C-SPBTLERF, CE EN 300 328 - removes need for end-product RF re-certification. |
| Ultra-Low-Power Design | 1.98 µA shutdown current and sub-1 mA average advertising current at 80 ms interval - enables >2-year CR2032 life. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Bluetooth LE network processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| nRF52833 DK | Requires external antenna and full BLE stack porting; higher peak current (10.5 mA RX) and no modular certification. | Best for developers needing custom protocol extensions or Nordic SDK integration. | Select when full SDK control and multi-protocol (Thread/Zigbee) capability outweigh certification and power trade-offs. |
| DA14531MOD | Smaller 2.0 × 2.5 mm package but lower Tx power (+0 dBm); lacks on-board antenna and requires external balun/filter. | Ideal for space-constrained designs where RF layout expertise exists and certification can be managed. | Choose for ultra-miniature wearables where board area is critical and RF design resources are available. |
Compared with nRF52833 DK and DA14531MOD, SPBTLE-RF0 delivers fastest time-to-market via pre-certified RF, lowest standby current, and zero-configuration BLE stack - making it optimal for volume OEMs prioritizing regulatory compliance and battery longevity over SDK flexibility.

FAQ
Does SPBTLE-RF0 require an external crystal oscillator?
No. The SPBTLE-RF0 integrates a 32 MHz crystal oscillator and a 32.768 kHz ring oscillator internally. The module is factory-configured for 32 MHz crystal operation and does not require external timing components - simplifying BOM and layout while ensuring Bluetooth timing accuracy.
Can SPBTLE-RF0 operate as both master and slave simultaneously?
Yes. Per Bluetooth v4.1 specification and ST documentation, SPBTLE-RF0 supports concurrent roles: it can act as a peripheral (slave) to two central devices while simultaneously scanning as a central (master) - enabling mesh-like topologies without host intervention.
What is the maximum SPI clock frequency supported?
The SPBTLE-RF0 supports SPI clock frequencies up to 8 MHz, as confirmed in the DS12080 datasheet section 5.1. This allows high-throughput ACI command/response cycles, reducing host MCU latency during firmware updates or burst data transfers.
Is antenna matching required when using SPBTLE-RF0?
No. The SPBTLE-RF0 integrates a tuned chip antenna, RF balun, and matching network. Layout guidelines specify a 6 mm keep-out zone around the antenna region, but no external matching components or impedance tuning are needed - enabling first-pass RF success.
