#122678 - features and compatibility
Responding to: ???'s previous message
hi,

Richard Erlacher said:

The Maxim/Dallas DS89C4x0 series (430..450, depending on how much FLASH you require) is a one-clocker, i.e. executes one instruction cycle per oscillator period, AND does so at rates up to 33 MHz.

I think it will work nicely.

...except that:
- you will lost ADC on-chip;
- you have to re-design PCB due the chips are not pin-to-pin compatible;
- prepared firmware should be re-wrote due different IAP/API;
- other?

Regards,
Oleg
