1 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 and 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, 1 x I
2
C interface, 14 GPIO, 2 x multifunction timer, 10-bit ADC, watchdog and 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.
