1 General description
The BLUENRG-M2SA is a Bluetooth Smart application processor module compliant with
Bluetooth
®
specifications v5.0 with embedded ceramic antenna.
The BLUENRG-M2SA module has been designed around the ST BlueNRG-2 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 BLUENRG-M2SA 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-2 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-2 SoC, the BLUENRG-M2SA 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-M2SA 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 & RTC, DMA controller, PDM stream processor).
The BLUENRG-M2SA module enables wireless connectivity into electronic devices, not
requiring any RF experience or expertise for integration into the final product. The
BLUENRG-M2SA 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-M2SA 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. BLUENRG-M2SA 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.
