Available in different versions (A/B/C)

All different and can be found at the www.atmel.com site.

ISP is possible using USB without any development kit.

You need ...

- power VCC vs GND
- PLL circuit active !!!!!!!!! otherwise USB will FAIL.
- Crystal connected
- proper reset signal
- ISP pin pulled low before reset
- recent flip version (www.atmel.com)
- EA connected to a logic level ('1').

This SHOULD work at all times .

Have fun in 2005,

Paul.
