5 / 60 page  2016-2019 Microchip Technology Inc. DS60001380B-Page 5 BM78 1.0 SYSTEM OVERVIEW The BM78 module is a fully-certified, embedded 2.4 GHz Bluetooth (BR/EDR/LE) wireless module. It includes an on-board Bluetooth stack, power manage- ment subsystem, 2.4 GHz transceiver, and RF power amplifier. Customers can embed Bluetooth functionality into any application using the BM78 module. The BM78 module enables rapid product development and faster time to market, and it is designed to provide integrators with the following features: • Simple integration and programming • Reduced development time • Superior wireless module with low-cost system • Interoperability with Bluetooth host • Wide range of applications The BM78SPPS5MC2/NC2 is a complete and fully reg- ulatory certified module with an integral ceramic chip antenna and RF shield. The BM78SPP05MC2/NC2 is a low-cost alternative with RF-out pin (for external antenna) and no RF shield. The integrator is responsi- ble for the antenna, antenna matching, and regulatory certifications. The BM78 module is a small, compact, and sur- face-mounted module with castellated pads for easy and reliable host PCB mounting. It is compatible with standard pick-and-place equipment and can inde- pendently maintain a low-power wireless connection. Low-power usage and flexible power management max- imize the lifetime of the BM78 module in battery oper- ated devices. A wide operating temperature range enable its applications in indoor and outdoor environ- ments. Figure 1-1 illustrates the internal block diagram of the BM78 module.
