Just cruising the DigiKey website, and I happened to come across three listings matching AVRISP:

ATAVRISP -- "PROGRAMMER AVR IN SYSTEM" -- $29.00
->the classic AVRISP, marked as "non-stock"

AVRISP mkII -- "PROGRAMMER AVR IN SYSTEM USB" -- $42.93
->the obvious choice for the mkII. Disappointingly expensive. Also marked as "non-stock". Perhaps a clerical error? (read on...)

ATAVRISP2 -- "PROGRAMMER AVR IN SYSTEM" -- $34.00
->This would be akin to the naming scheme that is actually used to differentiate the JTAG ICE from the JTAG ICE mkII in DigiKey's books. Marked as "out of stock" with an estimated ship date of January 17.

Perhaps, but not pertinent to the thread. The question is when the new USB equivalent of the ATAVRISP will be available, and at what price.

.

OK I miss-understood. I'm betting digikey will stock the new atavrisp, and Atmel is late (as usual) in getting product out the door.

It appears that you have misinterpreted me.

Digikey's "part number" for the original JTAGICE is ATJTAGICE.
Digikey's "part number" for the follow-up JTAGICE mkII is ATJTAGICE2.

Digikey's "part number" for the original AVRISP is ATAVRISP. If you had done a search for AVRISP any time last week, then that "part number" would be the only one that came up.

Following the pattern for the JTAGICE, DigiKey's "part number" for the AVRISP mkII would be ATAVRISP2.

However, today, DigiKey lists *two* new "part numbers":
"AVRISP mkII", and "ATAVRISP2". I was simply speculating that "AVRISP mkII" was a clerical error, and that "ATAVRISP2" was the correct entry/

hello,
seems that the avrisp mkii is "really" available at digikey, but estimated shipping date is end of january 2006.

Then, I guess the AVRISP-mkII isn't really abailable... That is, until sometime in January, 2006, now is it?

The old RS-232 AVRISP is being discontinued as well, I got a message from someone at Atmel about it. This pisses me off really badly because our production setup here relies on the RS-232 version which is optically isolated from the host PC for reasons I won't get into. Fiber optic USB isolators cost around $300 from B&B!

I like cats, too. Let's exchange recipes.

Same here, I purchased an AVRISP right before the AVRISP mkII was anounced. Atmel probably will stop adding support for new AVRs that come out as they did with the JTAGICE which makes me mad. :x OLIMEX's USBJTAGICE is optically isolated and isn't that expensive so that should something Atmel should consider.

Now that the old avrisp and avrice are obsolete and no longer supported
(for new devices, current avr studio releases still work with these for existing devices) Atmel should open source them. If the source code for the avrice and avrisp were released, the GNU avarice project could continue developement of them, and even add support for new devices.
Anybody up to reverse engineering (disassembly) these products for such a purpose?

I'll bet that the original AVRISP will continue to include support for new devices at least as long as the original STK500 continues to be their main prototyping board.

Furthermore, I've said it before, and I'll say it again: If you read over version 2 of the STK500 communication protocol, you'll notice that the AVRISP is never given an explicit message about what type of AVR device is being programmed...

Each command packet that is sent from the PC to the AVRISP includes data (extracted typically from AVR Studio's part description XML files) with instructions about ISP bit streams, delay values, expected polling results, etc. So the act of supporting a new AVR device shouldn't typically require any further changes to AVRISP firmware.

New firmware versions should only be required in the event that potential bugfixes arise, or if Atmel introduced a totally different ISP bitstream format. So far, they haven't shown any indication of doing that.

(Or, since the AVRISP shares firmware with the STK500, a new release may be necessary if support for a new topcard module or HV Programming procedure is introduced. None of these changes would affect the ISP portion of the firmware at all.)

Notice that, between February 2 2005 and September 2 2005, AVRISP had new device support for 8 parts added without any changes to the underlying FW version.

The XML-extracted data which is sent with AVRISP f/w 2.xx packets is taken from the data in the AVR Studio part description files. The exact same data source is used for packets sent to AVRISP mkII according to the protocol specification. The command packets for ISP programming via AVRISP f/w 2.xx are identical in structure and composition to the packets sent to AVRISP mkII.

That means that the XML file updates which add new device support to the AVRISP mkII will almost certainly also be applicable to original AVRISP hardware with f/w 2.xx.
