10 / 44 page  • One CAN • One USB OTG full-speed • Camera interface • DMA2D controller The device operates in the -40 to +85 °C (+105 °C junction) and -40 to +125 °C (+130 °C junction) temperature ranges from a 1.71 to 3.6 V for VDD power supply when using internal LDO regulator and a 1.05 to 1.32 V V DD12 power supply when using external SMPS supply. A comprehensive set of power-saving modes allows the design of low-power applications. Some independent power supplies are supported, such as an analog independent supply input for ADC, DAC, OPAMPs and comparators, a 3.3 V dedicated supply input for USB and up to 14 I/Os, which can be supplied independently down to 1.08 V. A VBAT input allows backup of the RTC and the registers. Dedicated VDD12 power supplies can be used to bypass the internal LDO regulator when connected to an external SMPS.

The module simultaneously supports multiple roles and can act at the same time as Bluetooth master and slave device. The BlueNRG-M2 is based on the BlueNRG-2 system-on-chip and provides a complete RF platform in a tiny form factor, integrating radio, embedded antenna and high frequency oscillators to offer a certified solution that optimizes the final application time-to-market. The BlueNRG-M2 can be directly powered by a pair of AAA batteries or any power source from 1.7 to 3.6 V.
