variations.

Simple 
corrections

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.

Three points

 about the Easy Radio ICTM

*

*: A separate coil is required for applications that include an AM radio

An FM radio can be easily included in a limited space in a small product
