Three points about the Easy Radio ICTM
No external | Miniature package | |||
components required * | ||||
| Ultraminiature | |||
Makes cost reductions possible |
| Achieves clear audio | ||

Changing Total Costs
1.The analog circuit design technology
2.Although even more time will be required to create the initialization block during software development, this block will be able to correct product
Furthermore, since software once developed can be reused in later products, this effort is not wasted.
Comparison of software development costs
Itemized comparison of software development costs
Although the first initialization is required, this can correct for product
