I bought these (40pence each), thinking they would do the job of the ATtiny 45s that I had used successfully before (but costing at least £1 each)
Would anyone familiar with this technology be kind enough to tell me if I am doing something wrong and can make the cheaper mcu's work or whether they will not work,please?
EDIT: Link didn't work, please copy and paste: this code into part number box: SC09163
and this one: SC09168
BUT I get error code thus:
avrdude: please define PAGEL and BS2 signals in the configuration file for part ATtiny45 //Usual acceptable error code
But this is not usual:
avrdude: stk500_program_enable(): protocol error, expect=0x14, resp=0x50
avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
this check.
Not even close to an ATtiny45. Different manufacturer. Different technology. Different toolset. It is certainly possible to get them to do something interesting / useful but not using any of the same tools you use with ATtiny45 processors.
To Coding Badly,
When I tried to buy £12 worth of chips from Mouser, the postage (to UK came up as £12! I have sent them a query about this.
Also, any idea what I can get the cheap chips I referred to, to do?
I only want to blink LEDs etc and £1 for ATiny's seems overkill.
If you are able to tell me if I can get the cheap chips to do something, would you be able to tell me what software I need to download to get the chip to be recognised by my arduino Uno, please (just as I had to downlaod software for the ATtiny 45?)

I don't. I believe there are a few frequent contributors here that are familiar with PIC processors. You will probably have to start a new topic with "PIC" in the subject to get attention.

The chip is 28 pin but you can blink alot of leds with it
Much better than Attiny if you have the space.
Also consider the low power version Atmega8L if you don't want to power them with 5V.
To Olof_N,
Thank you.
Mouser UK charge £12 postage even if you buy a single chip!
Subject: Change my Order
Comments: Is it really £12 to post 25 mcu's please? 556-ATTINY45-20PU
Thank you for contacting us. Pleas e note all of our stock ships directly from USA. The £12.00 shipping fee is the reduced charge we offer with FedEx on orders below £50.00 (standard sized items).
I hope this helps.
Please let us know if there is anything else in the mean time.

The ATMega8-16PU seems to be inferior in every way to the ATMega328-PU. Quarter the flash, half the SRAM, half the EEPROM, 16Mhz instead of 20Mhz, tighter voltage requirements (4.5V or better), and are actually more expensive at most suppliers (Digikey). What is the draw? If you are going to reserve 28 pins anyway, why not use the real deal that always works well with the Arduino environment? Buy 25 from Digikey for $1.88 each.
JoeN: First I suggested the Atmega8 as a low cost alternative to Atmega45/85 not Atmega328. The Atmega8 is a very good alternative (Ok 28 pin is a big drawback).
I also wrote that the low power version existed (Atmega8L).
Often 8KB is enough for a project, and how often do you need more speed than 16Mhz?
I don't know why you should buy them for the same price as Atmega328P when they cost 0,8$ (with free shipping!) on ebay.
I use Atmega8, Atmega328, Atmega1284 and Attinys, different MCU for different project.
