 		 #100360 - other way round
Responding to: ???'s previous message
Show me one modern FLASH microcontroller, especially self-programming (IAP) capable, which HAS NOT a self-timing FLASH programming. As per programming voltage (or as you call it, "height" of programming pulse), all modern FLASH memories employ logic level programming interface, with the actual programming voltage produced on-chip. As I mentioned, making it other way the manufacturer would be out of competition.

Atmel has a strange double-faced policy - they provide full programming information for some products while they frantically removed the traces of the parallel programming information from datasheets of other products. Nevertheless, in older Temic documents you will find enough evidence of parallel programming being self-timed, and there is no reason why they would depart from this scheme after being acquired by Atmel.

A factory-qualified parallel programmer is anyway out of question without having the full specs (presumably against NDA) so there is no reason arguing over one particular detail. I just wanted to point out that this piece of information you insist on is really getting slightly outdated these days.
