Providing IoT designers with secure over-air transmission, LPRS's easyRadio Integrated Controller (eRIC) is available with an AES 128 bit data encryption option. Available with operating frequencies for World Markets, the eRIC is just half the size and half the cost of the easyRadio range and can be set by users to operate in a number of low power modes offering current consumption as low as 32µA.

The advanced design of this transceiver uses SOC technology removing the need for an external processor. The on-board processor memory is partitioned giving half to the easyRadio configurable settings and communication software and leaving the rest available for design engineers to add their own application code. Code can be written using industry standard tools and a quick to learn application programming interface. This partitioned memory design will often eliminate the need for any additional microcontroller, saving cost, space and power.

eRIC is an exceptional value RF transceiver intended for embedded high-volume applications in the “Smart” or “IoT” arena including; building and lighting control, security, home monitoring and medical products, vehicle and contents monitoring, renewable energy control and remote sensor systems.

eRIC continues to use the popular and simple to use easyRadio programming protocols, operates in the ISM frequency bands (Europe 433 and 868MHz, USA 315 and 915MHz), meets ETSI and FCC requirements, has pin interface compatibility with existing easyRadio Advance (eRA) products, has a simple to use and customer configurable and programmable I/O interface, is designed for low power operation from batteries and has a built-in temperature sensor.

eRIC has been designed to simplify end product manufacture and is packaged for SMD assembly, measuring just 20x15x5mm.

Despite its small size and low cost eRIC still offers many advanced features including; secure communications using optional AES 128 bit data encryption, received signal strength indicator (RSSI) and carrier detect, network ID and digital channel select (DCS).

Barry Gillibrand, Managing Director of LPRS, comments, “eRIC builds on our many years of experience of supplying easyRadio wireless modules and is a significant product introduction into the high-volume wireless control and communication markets. Familiarity with our very successful easyRadio protocols ensures our existing customers a smooth transition and gives new customers the ability to configure operating frequency, bandwidth, output power, and data-rate ensuring multiple devices can communicate free from interference with each other and other nearby RF devices.”

In addition to designing and manufacturing the highly successful easyRadio Advanced (eRA) wireless modules in the UK, the full LPRS product range now includes, Raspberry Pi and Arduino Shield wireless platforms, the IQRF range of wireless networking components, the IQVC range of visual control panels together with antenna, wireless key fobs and a wide range of sensor products.
