1 General description

The SPBTLE-1S is a Bluetooth Smart application processor module compliant with

Bluetooth

specifications v4.2 with embedded ceramic antenna.

The SPBTLE-1S module has been designed around the ST BlueNRG-1 SoC where its

Cortex-M0 core can execute both Bluetooth protocols and customer application. A

complete power-optimized Bluetooth stack library provides:

• Master, slave, multiple roles support

• GAP: central, peripheral, observer or broadcaster roles

• simultaneous advertising and scanning

• capability of being slave of up to two masters simultaneously

• ATT/GATT: client and server

• SM: privacy, authentication and authorization

• L2CAP

• Link Layer: AES-128 encryption and decryption

The SPBTLE-1S has 160KB embedded Flash and 24KB embedded RAM memory.

In the module are available 32MHz and 32KHz crystal oscillators. It has been designed to

leverage the BlueNRG-1 integrated DC-DC step down converter.

It can be configured to support Single chip application or Network processor application.

Being based on the BlueNRG-1 SoC, the SPBTLE-1S module leverages all the tools and

documentation of its ecosystem: Development Kit, Application Notes, User Manuals,

Design Notes & Tips. A wide set of sample programs are also available in C source code.

The SPBTLE-1S module has a wide set of peripherals available for customer application (1

x UART interface, 1 x SPI interface, 2 x I

C interface, 14 or 15 GPIO, 2 x multifunction

timer, 10-bit ADC, Watchdog & RTC, DMA controller, PDM stream processor).

The SPBTLE-1S module enables wireless connectivity into electronic devices, not requiring

any RF experience or expertise for integration into the final product. The SPBTLE-1S

module provides a complete RF application platform in a tiny form factor (11.5 x 13.5 x 2.0

mm) and being a certified solution optimizes the time to market of the final applications.

The SPBTLE-1S module allows applications to meet the tight advisable peak current

requirements imposed with the use of standard coin cell batteries. Optimized results are

obtained with the embedded high-efficiency DC-DC step-down. SPBTLE-1S can be

powered directly with a standard 3 V coin cell battery, a pair of AAA batteries or any power

source from 1.7 to 3.6 V.
