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. 4 BLUENRG-M2Sx 2 Block diagram Figure 1.

- All unused pins should be left floating; do not ground.

- All GND pins must be well grounded.

- The area around the module should be free of any ground planes, power planes, trace routings, or metal for 6 mm from the module antenna position, in all directions.

- Traces should not be routed underneath the module. 7.1 Reset circuitry The BLUENRG-M2Sx module requires an external pull-up reset circuitry to ensure proper operation at power on. Refer to the "Reset management" chapter of the BlueNRG-2 datasheet for details. Figure 10. Reset circuitry If reset pin is controlled by an external host, there is no need to have RC circuit on the RESETn line. 7.2 Debug interface The BLUENRG-M2Sx embeds the ARM serial wire debug (SWD) port. It is two pins

(clock and single bi-directional data) debug interface, providing all the debug functionality plus real time access to system memory without halting the processor or requiring any target resident code.

(a) The pin DIO7/BOOT is monitored by bootloader after power up or hardware Reset and it should be low to prevent unwanted bootloader activation

(b) The function SPI_IN indicates that the pin is always an input when configured for SPI. Thus in case of SPI master role, it acts as MISO pin. In case of SPI slave role, this pin act as MOSI. See Table 6.

(c) The function SPI_OUT indicates that the pin is always an output when configured for SPI. Thus in case of SPI master role, it acts as MOSI pin. In case of SPI slave role, this pin act as MISO. See Table 6.

(e) BlueNRG-M2SA only Mechanical dimensions of the BLUENRG-M2SP Recommend land pattern top view Hardware design of the BLUENRG-M2SP Note:

- All unused pins should be left floating; do not ground.

- All GND pins must be well grounded.

- The area around the module should be free of any ground planes, power planes, trace routings, or metal for 6 mm from the module antenna position, in all directions.

- Traces should not be routed underneath the module. Reset circuitry The BLUENRG-M2SP module requires an external pull-up reset circuitry to ensure proper operation at power on. Refer to the "Reset management" chapter of the BlueNRG-2 datasheet for details. If reset pin is controlled by an external host, there is no need to have RC circuit on the RESETn line. Reflow soldering of the BLUENRG-M2SP The BLUENRG-M2SP is a high temperature strength surface mount Bluetooth module supplied on 20 pin (BLUENRG-M2SP) 4-layer PCB. The final assembly recommended reflow profiles are indicated here below. Soldering phase has to be executed with care: in order to avoid undesired melting phenomenon, particular attention has to be taken on the set up of the peak temperature. Here following some suggestions for the temperature profile based on following recommendations. Soldering profile Profile feature Average ramp up rate (TSMAX to Tp) Preheat Temperature min (TS mn) Temperature max (TS max) Time (tS min to tS max) (tS) Time maintained above:

Temperature TL Time tL Peak temperature (TP) Ramp down rate Time within 5 C of actual peak temperature (TP) PB-free assembly 3C/ sec max 150 C 200 C 60-100 sec 217 C 60-70 sec 240 + 0 C 10-20 sec 6 C/sec Time from 25 C to peak temperature 8 minutes max For a complete and detailed overview of additional technical info please consult the Data Sheet of the referenced BLUENRG-M2SP module.
