The BlueNRG-MS supports multiple roles simultaneously and can act at the same time as Bluetooth smart sensor and hub device. The Bluetooth Low Energy stack runs on the embedded ARM Cortex-M0 core. The stack is stored on the on-chip non-volatile Flash memory and can be easily upgraded via SPI. The device comes pre-programmed with a production-ready stack image(Its version could change at any time without notice). A different or more up-to-date stack image can be downloaded from the ST website and programmed on the device through the ST provided software tools. The BlueNRG-MS allows applications to meet the tight advisable peak current requirements imposed by standard coin cell batteries. The maximum peak current is only 10 mA at 1 dBm output power. Ultra low-power sleep modes and very short transition times between operating modes allow very low average current consumption, resulting in longer battery life. The BlueNRG-MS offers the option of interfacing with external microcontrollers via SPI transport layer.

It integrates a 2.4 GHz RF transceiver and a powerful Cortex-M0 microcontroller, on which a complete poweroptimized stack for Bluetooth single mode protocol runs, providing: Master, slave role support • • GAP: central, peripheral, observer or broadcaster roles • ATT/GATT: client and server • SM: privacy, authentication and authorization • L2CAP • Link Layer: AES-128 encryption and decryption An on-chip non-volatile Flash memory allows on-field Bluetooth low energy stack upgrade. In addition, according the Bluetooth specification v4.2 the BlueNRG-MS can support the following features through firmware updates: • Multiple roles simultaneously support • Support simultaneous advertising and scanning • Support being slave of up to two masters simultaneously • Privacy V1.1 • Low duty cycle directed advertising The device allows applications to meet of the tight advisable peak current requirements imposed with the use of standard coin cell batteries. If the high efficiency embedded DC-DC step-down converter is used, the maximum input current is only 15 mA at the highest output power (+8 dBm). Even if the DC-DC converter is not used, the maximum input current is only 29 mA at the highest output power, still preserving battery life. Ultra low-power sleep modes and very short transition time between operating modes result in very low average current consumption during real operating conditions, providing very long battery life. Two different external matching networks are suggested: standard mode (TX output power up to +5 dBm) and high power mode (TX output power up to +8 dBm). The external host application processor, where the application resides, is interfaced with the BlueNRG-MS through an application controller interface protocol which is based on a standard SPI interface.

In the following subsections a short description of each module is given. Figure 9. Block diagram 5.1 Core, memory and peripherals The BlueNRG-MS contains an ARM Cortex-M0 microcontroller core that supports ultra-low leakage state retention mode and almost instantaneously returning to fully active mode on critical events. The memory subsystem consists of 64 kB Flash, and 12 kB RAM, divided in two blocks of 6 kB (RAM1 and RAM2). Flash is used for the M0 program. No RAM or FLASH resources are available to the external microcontroller driving the BlueNRG-MS. The application controller interface (ACI) uses a standard SPI slave interface as transport layer, basing in five physical wires: • 2 control wires (clock and slave select) • 2 data wires with serial shift-out (MOSI and MISO) in full duplex • 1 wire to indicate data availability from the slave DS10691 - Rev 9 page 12/42 BlueNRG-MS Power management Table 3.

All the SPI pins, except the CSN, are in high impedance state during the low-power states. The IRQ pin needs a pull-down external resistor. The device embeds a battery level detector to monitor the supply voltage. The characteristics of the battery level detector are defined in Table 18. Auxiliary blocks characteristics. 5.2 Power management The BlueNRG-MS integrates both a low dropout voltage regulator (LDO) and a step-down DC-DC converter, and one of them can be used to power the internal BlueNRG-MS circuitry. However even when the LDO is used, the stringent maximum current requirements, which are advisable when coin cell batteries are used, can be met and further improvements can be obtained with the DC-DC converter at the sole additional cost of an inductor and a capacitor. The internal LDOs supplying both the 1.8 V digital blocks and 1.2 V digital blocks require decoupling capacitors for stable operation. When the VBAT voltage is below 1.8 V, the LDO 1.8 V output follows the VBAT value. Figure 10. Power management strategy using LDO and Figure 11. Power management strategy using step-down DC-DC converter, show the simplified power management schemes using LDO and DC-DC converter. Figure 10.

The low frequency clock is used in Low Power mode and can be supplied either by a 32.7 kHz oscillator that uses an external crystal and guarantee up to ±50 ppm frequency tolerance, or by a ring oscillator with maximum ±500 ppm frequency tolerance, which does not require any external components. The primary high frequency clock is a 16 MHz or 32 MHz crystal oscillator. There is also a fast-starting 12 MHz ring oscillator that provides the clock while the crystal oscillator is starting up. Frequency tolerance of high speed crystal oscillator is ±50 ppm. The usage of the 16 MHz (or 32 MHz) crystal is strictly necessary. 5.4 Bluetooth low energy radio The BlueNRG-MS integrates a RF transceiver compliant to the Bluetooth specification and to the standard national regulations in the unlicensed 2.4 GHz ISM band. The RF transceiver requires very few external discrete components. It provides 96 dB link budgets with excellent link reliability, keeping the maximum peak current below 15 mA. In Transmit mode, the power amplifier (PA) drives the signal generated by the frequency synthesizer out to the antenna terminal through a very simple external network. The power delivered as well as the harmonic content depends on the external impedance seen by the PA. The output power is programmable from -18 dBm to +8 dBm, to allow a user-defined power control system and to guarantee optimum power consumption for each scenario. DS10691 - Rev 9 page 14/42 BlueNRG-MS Operating modes 6 Operating modes Several operating modes are defined for the BlueNRG-MS: • Reset mode Sleep mode • • Standby mode • Active mode • Radio mode – Receive radio mode – Transmit radio mode In reset mode, the BlueNRG-MS is in ultra-low power consumption: all voltage regulators, clocks and the RF interface are not powered. The BlueNRG-MS enters Reset mode by asserting the external reset signal. As soon as it is de-asserted, the device follows the normal activation sequence to transit to Active mode. In sleep mode either the low speed crystal oscillator or the low speed ring oscillator are running, whereas the high speed oscillators are powered down as well as the RF interface. The state of the BlueNRG-MS is retained and the content of the RAM is preserved. Depending on the application, part of the RAM (RAM2 block) can be switched off during sleep to save more power (refer to stack mode 1, described in UM1868). While in sleep mode, the BlueNRG-MS waits until an internal timer expires and then it goes into Active mode. The transition from Sleep mode to Active mode can also be activated through the SPI interface. Standby mode and Sleep mode are equivalent but the low speed frequency oscillators are powered down. In Standby mode the BlueNRG-MS can be activated through the SPI interface. In Active mode the BlueNRG-MS is fully operational: all interfaces, including SPI and RF, are active as well as all internal power supplies together with the high speed frequency oscillator. The MCU core is also running. Radio mode differs from Active mode as also the RF transceiver is active and it is capable of either transmitting or receiving. Figure 12.

DS10691 - Rev 9 page 16/42 BlueNRG-MS Application controller interface 7 Application controller interface The application controller interface (ACI) is based on a standard SPI module with speeds up to 8 MHz. The ACI defines a protocol providing access to all the services offered by the layers of the embedded Bluetooth stack. The ACI commands are described in the BlueNRG-MS ACI command interface document (UM1865). In addition, the ACI provides a set of commands that allow to program BlueNRG-MS firmware from an external device connected to SPI. The complete description of updater commands and procedures is provided in a separate application note (AN4491).
