General description

The SPBTLE-1S is a Bluetooth Low Energy 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 160 KB embedded Flash and 24 KB embedded RAM memory.

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

leverage the BlueNRG-1 integrated DC-DC step down converter in order to achieve best

power consumption in active mode.

It can be configured to support both application processor (host-less) and network

processor (hosted) modes.

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 I2C interface, 14 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 as with a pair of AAA batteries or any

power source from 1.7 to 3.6 V.
