eRIC Radio Transceiver Preliminary Data Sheet The easy Radio Intelligent Controller (eRIC) radio transceiver module is based on the Texas Instruments CC430F5137 System-on-Chip device to provide an intelligent radio sub-system that combines a high performance RF transceiver, RF band pass filters (BPF), an MSP430 microcontroller, 32Kb flash memory, non-volatile flash storage, temperature sensor, and a low drop voltage regulator. The device operates on the International licence exempt Industrial, Scientific and Medical (ISM) radio bands. eRIC thus extends the proven easyRadio product line by offering a low cost RF transceiver intended for high volume applications. The compact form factor, surface mount packaging and external antenna connector simplify product design and manufacture and provide for flexible placement of the module within an end product. Features Benefits          Simple serial data in/data out user interface and configuration 433 & 868MHz (UK & Europe), 315 & 915MHz (USA) Meets ETSI (Europe) & FCC Certified (USA) requirements Simplifies product design and manufacture Battery powered applications Can eliminate need for external application processor Minimises external hardware requirements for custom applications Secure communications Environment monitor Default ‘easyRadio’ Protocol Embedded ISM Frequency Bands Radio Approvals Small 15x20x2.2mm Surface Mount Device (SMD) Low power operation capable eROS Operating System & Application partitions Configurable & programmable User I/O AES 128 bit data encryption Built in Temperature Sensor easyRadio Operating System (eROS) eRIC’s processor memory is partitioned and embedded with a protected version of the easyRadio Operating System (eROS) that handles all the complex radio functions and thus eliminates the need for the user to program multiple control registers and understand their interaction. The other partition provides an optional user accessible application code area. Radio parameters such as frequency, channel, output power and data rate are passed by the application code and radio data is sent and received in the background by simply calling predefined functions. Also provided is a simple to use API that replaces low level chip specific code with intuitive pin commands that allow the multiple general purpose I/O pins and internal function blocks to be configured and interfaced to external hardware. These built in functions make customisation easy for the novice and powerful for advanced programmers. This architecture can eliminate the need for a separate application microcontroller and thus minimises cost and power consumption for simple ‘sense and control’ RF nodes such as might be employed within the ‘Internet of Things’. By default (factory settings) the application code area is pre-programmed with a subset of the familiar easyRadio command and communication software that allows key operating parameters such as operating frequency, RF power output and host communication settings to be (optionally) pre-configured using the ‘easyRadio Companion’ software or to be dynamically changed using simple serial commands sent from the host processor. This allows multiple eRIC devices to communicate free from interference with each other and other local RF devices. In the default application mode, data is sent to and received from host processors or devices using 3.3V logic level serial data (inverted) with packet sizes up to 250 bytes.

The transceiver will then be ready to transmit or receive (default) and would normally be left in this state, ready to receive data. The internal Vreg is not brought out to a specific pin/pad. Should there be need to connect external pull up resistors then connection should be made to a spare GPIO pin/pad configured as a ‘High’ Output. Power Supply The supply used to power the transceiver should be ‘clean’ and free from ripple and noise (
