Product details
Overview
SPBTLE-RF0TR 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 TX power, -88 dBm RX sensitivity, and on-board chip antenna in a 13.5 × 11.5 × 2 mm LGA package. It enables host MCU connectivity via SPI for wearables and battery-powered IoT edge nodes.
For engineers reviewing the SPBTLE-RF0TR datasheet, SPBTLE-RF0TR pinout, SPBTLE-RF0TR application, or SPBTLE-RF0TR equivalent, key selection criteria include simultaneous master/slave role support, field-upgradable stack over SPI, 1.7–3.6 V operation, ultra-low standby current (1.98 µA), and FCC/IC/CE modular certification compliance.
Technical Context
The SPBTLE-RF0TR implements a complete Bluetooth LE protocol stack in ROM and Flash, supporting concurrent central/peripheral/observer/broadcaster GAP roles, ATT/GATT client/server, SM privacy/authentication, and L2CAP connection-oriented channels. Its BlueNRG-MS core includes AES hardware acceleration and supports LE Ping, directed advertising, and 32-bit UUIDs.
Hardware integration centers on an SPI host interface (CLK/MISO/MOSI/CS/IRQ), active-low reset, and dual-clock architecture: 32 MHz crystal oscillator for RF timing and 32.768 kHz ring oscillator for low-power sleep timing. All unused pins (EXT_LPCLK, GPIO2, ANA_TEST0) are NC and must remain floating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bluetooth Version | v4.1 compliant with simultaneous master/slave roles and LE Ping support |
| TX Output Power | +4 dBm - sufficient for 10–15 m line-of-sight range with on-board antenna |
| RX Sensitivity | -88 dBm - enables reliable reception under weak-signal conditions (e.g., inside enclosures) |
| Link Budget | 92 dB - calculated as TX + |RX|; ensures robust link margin in noisy environments |
| Supply Voltage | 1.7–3.6 V - compatible with coin cell (3 V), AAA batteries (3 V), or regulated LDO outputs |
| Standby Current | 1.98 µA - extends shelf life and operational runtime in intermittently active devices |
| Operating Temp | -40 °C to +85 °C - validated for industrial and consumer wearable deployment |
Pinout & Package
SPBTLE-RF0TR uses an 11-pin LGA package (13.5 × 11.5 × 2 mm) with exposed thermal pad. All pins are 3.3 V tolerant; unused pins (EXT_LPCLK, GPIO2, ANA_TEST0) must be left floating per design requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Vin (Pin 5) | Power input | Accepts 1.7–3.6 V supply; powers internal LDO and RF/analog blocks |
| GND (Pin 6) | Ground reference | Must be low-impedance connection; all GND pins require solid plane tie-in |
| SPI_IRQ (Pin 4) | Interrupt output | Active-high signal indicating pending data or event for host SPI polling |
| SPI_CLK (Pin 7) | SPI clock input | Max 8 MHz; synchronous timing reference for bidirectional SPI transfers |
| SPI_MISO (Pin 8) | SPI master-in/slave-out | Host reads module responses and status via this unidirectional output |
| SPI_MOSI (Pin 9) | SPI master-out/slave-in | Host sends commands, configuration, and payload data to module |
| SPI_CS (Pin 10) | SPI chip select | Active-low enable; required to initiate each SPI transaction sequence |
| BT_RESET (Pin 11) | Reset input | Active-low; must be held low until Vin stabilizes to prevent initialization failure |
Key Features
| Feature | Design Value |
|---|---|
| Embedded BLE Stack | Full protocol stack (GAP/GATT/SM/L2CAP/LL/RFPHY) preloaded in nonvolatile memory - eliminates host-side stack porting effort |
| Field Firmware Upgrade | SPI-based in-system update of BLE stack binaries - enables security patching and feature enhancements without hardware change |
| Modular Certification | FCC ID S9NSPBTLERF, IC 8976C-SPBTLERF, CE EN 300 328/EN 301 489-17 - reduces end-product regulatory testing scope and time-to-market |
| Ultra-Low Power Design | 1.98 µA shutdown current and adaptive duty-cycling (e.g., 0.34 mA avg. at 80 ms advertising interval) - extends coin-cell lifetime to >1 year |
| Integrated RF Front-End | On-board chip antenna, BALUN, and 32 MHz crystal - eliminates external RF matching, filtering, and clock sourcing components |

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 |
|---|---|---|---|
| nRF52832-QFAA | SoC (ARM Cortex-M4F + BLE radio); requires external stack porting and RF tuning | Demands full software stack development and RF validation; no modular certification | Select when custom BLE profile logic or high-speed sensor fusion is needed on same die |
| DA14585-01FXQ | Single-mode BLE SoC with integrated PMU; lower TX power (+2.5 dBm), no on-board antenna | Requires external antenna matching network and separate DC-DC design; FCC/IC certification not modular | Select for cost-sensitive designs where PCB space allows antenna layout and regulatory budget permits full-system certification |

FAQ
Does SPBTLE-RF0TR support Bluetooth mesh networking?
No. SPBTLE-RF0TR implements only Bluetooth v4.1 LE protocols (GAP/GATT/SM/L2CAP/LL) and does not support Bluetooth mesh profile or mesh networking features introduced in v5.0+. Mesh capability requires firmware and hardware extensions beyond this module's architecture and certified stack footprint.
Can SPBTLE-RF0TR operate without an external crystal?
No. The SPBTLE-RF0TR requires the onboard 32 MHz crystal oscillator for RF timing accuracy and BLE channel hopping compliance. The 32.768 kHz ring oscillator is used only for low-power sleep timing and cannot replace the 32 MHz crystal for radio operation.
What is the maximum SPI clock frequency supported?
The SPBTLE-RF0TR supports up to 8 MHz SPI clock frequency for host communication. Exceeding this limit may cause command corruption or synchronization loss; ST recommends using 4–6 MHz for robust noise immunity in industrial layouts with long traces or shared PCB layers.
Is the on-board chip antenna directional or omnidirectional?
The on-board chip antenna is omnidirectional in the XY plane (parallel to PCB surface) with peak gain of ~1.5 dBi and typical 3 dB beamwidth of 120°. Radiation pattern is intentionally suppressed below the module to minimize ground-plane coupling - antenna performance assumes ≥6 mm clearance from surrounding metal or ground planes.
