RF transceivers are wireless devices that act as transmitters and receivers to support data transmission. The RN4020BCN-V/RM120 is an advanced 2.4GHz Bluetooth Low Energy (BLE) System on Chip (SoC) transceiver module designed with high reliability for easy integration into various applications. This module integrates an RF front end, power amplifier, link layer, and a 2MHz Cortex-M3 processor to provide a secure, robust and more efficient implementation of the BLE communications protocol.

The RN4020BCN-V/RM120 operates in the 2.4GHz ISM frequency band and offers a nominal range of up to 250feet. It supports all Bluetooth Low Energy profiles for easy integration into existing systems, including the Serial Port Profile (SPP) for classic Bluetooth serial emulation communication, and the iAP2 protocol for Apple accessory authentication.

Using an advanced power amplifier design, the module also supports multiple modulation schemes, making it highly versatile for various applications. Clear RF output can be adjusted up to 20dBm, improving communication range and eliminating any potential signal interference.

The RN4020BCN-V/RM120 also features a host of features for increased security, including AES-128 encryption, resilience against play-attack, Bluetooth pairing, timeout inactivity, and pin-change by remote (host) commands. This ensures reliable data transmission with secure authentication. Additionally, the module’s increased power efficiency enables the use of smaller, less expensive batteries for longer run-times.

In order to reduce the complexity of software development, the company offers a comprehensive set of software development tools as well as a number of example applications to facilitate rapid prototyping and implementation. These tools include useful libraries for interacting with the module, such as the BLE profiles, and the RN4020 Configuration Utility, which implements a command line interface for configuring the module. This utility can also be used to remotely reset and configure the RN4020BCN-V/RM120 remotely.

In terms of power consumption, the module’s idle state consumption is less than 6mA typical. When transmit and receive signals, the power consumption increases to only 10 mA at 0 dBm output power, making it highly energy-efficient. During Sleep mode, the power consumption can be as low as 15μA.

The RN4020BCN-V/RM120 is ideal for applications requiring low-cost and secure wireless data transmission, including home automation, industrial automation, medical device communication, and remote asset tracking and monitoring. With its compact form factor and wide range of communication options, this transceiver module is suitable for a wide variety of applications and is a great choice for customers seeking a cost-effective solution with high reliability and robustness.
