Itemized comparison of software
development costs
Although the first initialization is required, this
can correct for product sample-to-sample
variations.

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 IC
TM
*
*: 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
