SYSTEM OVERVIEW

The BM78 module is a fully certified, embedded 2.4 GHz

Bluetooth version 4.2 (BR/EDR/LE) wireless module. It

includes an on board Bluetooth stack, a power manage-

ment subsystem, a 2.4 GHz transceiver, and an RF

power amplifier. Customers can embed Bluetooth func-

tionality into any applications using the BM78.

The BM78 enables rapid product development and

faster time to market, and it is designed to provide inte-

grators 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 BM78 has four Stock Keeping Units (SKUs). For

additional information on SKUs, refer to Section 9.0

“Ordering Information”. The BM78SPPS5MC2/NC2

is a complete and fully regulatory certified module with

an integral ceramic chip antenna and RF shield. The

BM78SPP05MC2/NC2 is a low-cost alternative with

RF out PAD (for external antenna) and no RF shield.

The integrator is responsible for the antenna, antenna

matching, and regulatory certifications.

The BM78 is a small, compact, and surface mounted

module with castellated pads for easy and reliable host

PCB

mounting.

compatible

with

standard

pick-and-place equipment and can independently main-

tain a low-power wireless connection. Low power usage

and flexible power management maximize the lifetime of

the BM78 in battery-operated devices. A wide operating

temperature range enables its applications in indoor and

outdoor environments. Figure 1-1 illustrates the internal

block diagram of the BM78.
