Three points about the Easy Radio ICTM

No external	Miniature package		High-sensitivity reception
components required *
		Ultraminiature
Makes cost reductions possible			Achieves clear audio
	5	⋅ 5 ⋅ 0.8 mm3 size

Changing Total Costs

1.The analog circuit design technology (know-how based on long experience) that has been necessary up to now is no longer required.

2.Although even more time will be required to create the initialization block during software development, this block will be able to correct product sample-to-sample variations, radically reducing the testing and adjustment during the manufacturing process, and as a result, reduce total costs.

Furthermore, since software once developed can be reused in later products, this effort is not wasted.

Although the first initialization is required, this can correct for product sample-to-sample variations.
