Low power MCUs form core of solution kit

The RL78/I1D microcontroller group offers a comprehensive set of analogue features. The small 48-pin package includes four operational amplifiers, two comparators and 17 input channels for the 12-bit ADC converter.

The smart peripherals of the RL78/I1D are able to work without CPU intervention and in low power modes, offering a significant power saving down to 124µA at 1MHz in operation. Fast wake-up time reduces power consumption even more and enables the device to react faster, making it especially beneficial for communication protocols.

The smart peripherals can transfer and compare data, perform addition and subtraction and link one peripherals operation to another peripheral, thus offering new possibilities to developers of detector applications.

Detect it! has four hardware boards, a motion detector demonstrator, a smoke detector demonstrator, a carbon monoxide demonstrator, and a glass-break detector demonstrator. Each of the boards provides a solution for the associated detectors. The smoke detector senses smoky environments by the scattering of the infrared signal in a smoke chamber.

Motion is detected using PIR technology. The glass-break detector analyses sounds and can differentiate window-break sounds from the surrounding environment. By using a chemical sensor, the carbon monoxide detector measures the concentration of the gas in the surrounding air.

The Detect it! solution kit is ready for use out of the box. It provides a good, fast and cost-efficient starting point to the developer as it includes the source code of the demonstration sample programs, the environment development installer of IAR Embedded Workbench, the Gerber files and the schematics, and a comprehensive user manual.
