RN4677
1.0 DEVICE OVERVIEW
The RN4677 is a complete, fully certified, embedded
2.4 GHz Bluetooth® version 4.0 (BR/EDR/LE) wireless
module. It incorporates an on-board Bluetooth stack,
cryptographic accelerator, power management
subsystem, 2.4 GHz transceiver and RF power
amplifier, see Figure 1-1. With the RN4677, designers
can embed Bluetooth functionality rapidly into virtually
any device.
The RN4677 provides cost and time-to-market savings
as a self-contained module solution. The module has
been designed to provide integrators with a simple
Bluetooth solution that contains the following features:
• Ease of integration and programming
• Vastly reduced development time
• Minimum system cost
• Interoperability with Bluetooth hosts
• Maximum value in a range of applications.
The RN4677 can independently maintain a low-power
wireless connection. Low-power usage and flexible
power management maximize the module's lifetime in
battery-operated devices. A wide operating
temperature range enables use in indoor and outdoor
environments (industrial temperature range).
The RN4677 module comes in two varieties. The
RN4677 is a complete, fully regulatory certified module
with integral ceramic chip antenna and shield. The
RN4677U is a lower cost alternative with external
antenna and no shield. The integrator is responsible for
the antenna, antenna matching, and regulatory
certifications.
The RN4677 is a small, compact, surface mount
module with castellated pads for easy and reliable host
PCB mounting. The module is compatible with
standard pick-and-place equipment.
