substitute for ATTINY85V-10-PU ?

Post by lazart »

hello,
the ATTINY85V-10-PU is unavailable in my area. is there a substitute?
i want to use it in the tv-b-gone and the shipping costs in a foreign contry for just one chip at adafruit is so much.

greets,
lazart

Afaik the Tiny85 was choosen because of it's large (8k) flash memory and i don't know of any equivalent atmel chip with a higher availability..
You might substitute the tvbgone with a similar device ;) For example i've seen the unzap http://www.lochraster.org/unzap/?en which uses the ATmega 48/186 which has a better availability (at leased for me)..

uhe assumed a tvbgone, but you didn't specify what your requirements were.

What is the voltage the AVR is supplied with in your project? If you don't need operation below 2.7 volts (the 85V operates down to 1.8 at reduced clock speed if I recall correctly), you can substitute any ATTiny85 in -PU packaging.

The way to decode the part number is:
ATTiny25/45/85 - Same family, all pin/code compatible, just with different amounts of flash. 2k/4k/8k respectively
V - Low voltage version
-10 - Max clock speed of 10 MHz. Non V versions are usually -20
-PU - Plastic DIP packaging

So if you don't need low voltage operation, try looking for the ATTiny85-20-PU
