Application fields

The EZR32LG230F128R67G-B0R is a low power, low data rate wireless transceiver ideal for applications where low power, excellent range and low cost are important factors. It is ideally suited for wireless sensing and monitoring applications such as medical, industrial, and home automation. Its low power consumption makes it ideal for battery powered wireless applications. It can be used for a variety of applications, such as temperature or moisture sensing, asset tracking, healthcare monitoring, home automation, and industrial automation.

Operating Principles

The EZR32LG230F128R67G-B0R transceiver operates using a single-chip transceiver that combines an RF transmitter and an RF receiver in one package. It features a direct conversion transceiver architecture with mono-conversion technology. This type of architecture is used to eliminate the need for an IF filter which reduces the cost, size and power consumption. The EZR32LG230F128R67G-B0R transmits and receives radio frequency signals within the 2.4 GHz ISM (industrial, scientific and medical) band. The integrated receiver in the transceiver operates from -30dBm to -90dBm, with dynamic range from 30 dBm to 90 dBm. The integrated transmitter is designed to operate over a wide frequency range of 2400 to 2524 MHz.

The EZR32LG230F128R67G-B0R devices employ a spread spectrum radio solution that allows multiple radios to operate in the same area. This technique reduces interference and increases the range of the device. It also has an integrated and adjustable digital signal processing unit for image rejection, automatic gain control (AGC), data rate control, and packet error rate control. The integrated low-frequency filter allows for improved band edge performance. The device also includes an industry-standard 32-bit ARM Cortex-M4T processor which provides a power-efficient microcontroller environment with integrated memory for data storage and processing.

The device also includes an AFE (analog front end) and a power management module that helps reduce power consumption in idle and low-power modes. The EZR32LG230F128R67G-B0R devices are also equipped with a 64-bit security key (AES-128) and integrated AES coprocessor which can be used for secure data communication and authentication.
