Kanda AVR Handheld programmers have been popular for the last 20 years and are constantly being improved. They have always supported ISP and JTAG on ATxmega and ATtiny and in the last few years we have added both ATxmega JTAG and PDI interfaces.

 

Now we have added a TPI interface to support newer ATtiny devices. We are currently adding UPDI interface for the other new ATtiny chips. Are these popular chips and what is the preferred ISP connector for them, 6-way 3x 2 header?8-way AVR and ATxmega Handheld Programmer Picture

Yes, and probably the 3x2 0.1" connectors as it is the most standard.

 

There is a sort of mapping of UPDI onto the 6-pin by Microchip in the attached document. It's the pinout for the Pickit 4 but you can read across what lines to use...

 

 

Also, any plans to add that feature to the keyfobs? I own quite a few of them...

UPDI on the MISO pin. That agrees with the table above.

Likely yes as are now at a Microchip wafer fab.

PB megaAVR, some mega328; unified memory AVR (UPDI) : tinyAVR 0-series, tinyAVR 1-series, megaAVR 0-series :

Product Change Notification - GBNG-06LXXH156 - 25 Jun 2018 - CCB 2856 Final Notice: Qualification of Microchip Fabrication site (FAB 4) for selected Atmel products manufactured with the 59.91K process technology.
