MODES OF OPERATION

The SmartMesh IP Mote software can be operated in three

distinct modes, namely, namely Slave, Master, and On-

Chip SDK. Mode selection should be considered during

thearchitecture/designphaseofthedevelopmentprocess.

Slave Mode

In Slave mode, the Eterna is connected to an external

microprocessor through the API UART and is solely used

as a networking device. None of the built in I/Os are ac-

cessible in this mode. Refer to the SmartMesh IP User's

Guide for more detailed information.

Master Mode

In Master mode, no external µProcessor is required and a

limited set of functionality is made available with no pro-

gramming required on the device. The following features

are available

On-Chip Temperature Sensor

4 Analog Inputs

4 Digital Inputs

3 Digital Outputs

Refer to the SmartMesh IP User's Guide for more detailed

information.

On-Chip SDK (OCSDK)

TheSmartMeshIPOn-ChipSoftwareDevelopmentKit(On-

ChipSDK)enablesdevelopmentofC-codeapplicationsfor

real-time operating system. With the On-Chip SDK, users

may quickly and easily develop application code without

the need for an external microprocessor.

Applications written within the On-Chip SDK may send

andreceivewirelessmessagesthroughthemeshnetwork;

process data, such as statistical analysis; execute local

decision-making and control; and manage the following

peripherals:

General Purpose Input-Output (GPIO) pins

Analog-to-Digital Converter (ADC)

Universal Asynchronous Receiver/Transmitter

(UART)

Serial Peripheral Interface (SPI) Master

Inter-Integrated Circuit (I2C) Master

1-Wire Master

Network connectivity and quality of service is handled by

theSmartMeshIPprotocolstack.TheSmartMeshIPstack

comes as a pre-compiled library and delivers >99.999%

data reliability while providing ultra low power operation.

REGULATORY AND STANDARDS COMPLIANCE

Radio Certification

The LTP5901 and LTP5902 have been certified under a

single modular certification, with the module name of

ETERNA2. Following the regulatory requirements pro-

vided in the ETERNA2 User’s Guide enables customers

to ship products in the supported geographies, by simply

completing an unintentional radiator scan of the finished

product(s). The ETERNA2 User’s Guide also provides

the technical information needed to enable customers

to further certify either the modules or products based

upon the modules in geographies that have not or do not

support modular certification.

Compliance to Restriction of Hazardous Substances

(RoHS)

Restriction of Hazardous Substances 2 (RoHS 2) is a

directive that places maximum concentration limits on

the use of certain hazardous substances in electrical and

electronic equipment. Linear Technology is committed to

meeting the requirements of the European Community

directive 2011/65/EU.
