Hey Bert

You'll have to devide the atmel controlers in two types:

"the older ones" wich is AT89C1051, 2051, 4051 and AT89C51, AT89C52 and a few others.

These devices need a paralel programmer.

There is the AT89S8252, wich is a isp device, but still need some programmer hardware, and the chip Erik mentioned - Atmel reached revision S, before it worked.

And finaly there is the T89 series of chips, bought in from Temic. This series includes the USB and CAN devices. All this stuff can be programmed without anything more than the chip it self, a TTL to RS232 converter (MAX 232) and FLIP - free from the Atmel web side.

Godt nytår
