ZigBee Smart Energy is deemed to be on of the world wide industry standard for wireless meter reading applications. The ZigBee PRO Smart Energy profile defines various device types and the specification for each device. The radio module AMBZ420-SE is based on a ZigBee PRO compliant platform and provides a complete ZigBee PRO protocol stack including the support for the ZigBee Smart Energy profile 1.0 / 1.1. The radio module supports the Certificate Based Key Exchange (CBKE), the entire Key-Establishment cluster is embedded in the ZigBee module.

The Smart Energy application (e.g. meter, consumption display) will be implemented in an external microcontoller (MCU). The SE application communicates with the RF module via UART or SPI serial interface. The RF module can support any device specified in SE profile specifications 1.0 / 1.1. The Smart Energy Certificates can be embedded into Zigbee module through serial interface thus making handling and logistics much easier.

The AMBZ420-SE is a compact, powerful 2.4 GHz transceiver module. It combines the latest transceiver technology with a sophisticated antenna circuit in a compact module. With only a few external components, a complete ZigBee compatible network solution can be built. Due to its small size, outstanding performance at low power consumption and easy modular handling, the AMBZ420-SE is leading the way for the new generation of ZigBee OEM modules.

Easy to integrate
The integrated 2.4 GHz transceiver offers full IEEE 802.15.4 compatibility as well as excellent receiver sensitivity and robustness, thus building a reliable interface to the antenna. The pre-qualified module enables its user to create a ZigBee product within the shortest possible time to market.

The radio module is available with following antenna options: SMD ceramic antenna, as well as external antenna, connected either via U.FL connector or antenna pad.

Microcontroller
The AMBZ420-SE provides a high-performance microcontroller with 8051 core. Different modes are available in addition to the rich periphery such as UART, SPI, timer, A/D converter, and more. The numerous GPIO pins, a random number and an interrupt generator provide other additional uses. The AMBZ420-SE also provides functionalities such as CRC calculation, acknowledgments, clear channel assessment, RSSI, an AES-128 security module and automatic MAC layer measurements.

Fields of application
Wireless meter reading applications / home automation. Due to the small size and the low power consumption, the AMBZ420-SE is perfectly suitable for battery-powered applications.
