1 General description
The BLUENRG-M2SA and BLUENRG-M2SP are Bluetooth Smart application processor
modules compliant with Bluetooth
®
specifications v5.0.
The BLUENRG-M2Sx module has been designed around the ST BlueNRG-2 SoC where its
Cortex-M0 core can execute both Bluetooth protocols and customer application. Optimized
memory architecture includes 256 KB of Flash memory and 24 KB of ultra-low-leakage
RAM (with full data retention). 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
In the BLUENRG-M2SA module are available both 32MHz and 32KHz crystal oscillators. It
has been designed to leverage the BlueNRG-2 integrated DC-DC step down converter in
order to achieve best power consumption in active mode. It also embeds a high efficiency
chip antenna.
It can be configured to support both application processor (host-less) and network
processor (hosted) modes.
Being based on the BlueNRG-2 SoC, the BLUENRG-M2Sx 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 BLUENRG-M2Sx module has a wide set of peripherals available for customer
application (1 x UART interface, 1 x SPI interface, x I2C interface,14 GPIO,2 x
multifunction timer,10-bit ADC,Watchdog & RTC,DMA controller,PDM stream processor).
The BLUENRG-M2Sx module enables wireless connectivity into electronic devices, not
requiring any RF experience or expertise for integration into the final product. The
BLUENRG-M2Sx 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 BLUENRG-M2Sx module allows applications to meet the tight advisable peak current
requirements imposed with the use of standard coin cell batteries. Optimized results are
obtained when the embedded high-efficiency DC-DC step-down converter is used
(BLUENRG-M2SA). Instead, for the BLUENRG-M2SP the best performances in terms of
power consumption are achieved using a 1.8V DC power supply. BLUENRG-M2Sx 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.
