Qustion:

Is there any known difference between the new EA DIP205 and the EA DIP203 ?

Answer:

Thank you for your request. As you may know, the reason for then new p/n is that the controller changed from SSD1803 (obsolete in the mean time) to RW1073.

The specification of both controllers is 100% compatible.

In SPI mode we found out during extensive tests that the SSD1803 runs with a clock of up to 3 MHz (but thus far outside the specification !) and the RW1073 up to 1.5 MHz only. But both work fine within the specification of 1 MHz (tC= 1µs).
