ATMEGA328 TQFP PDF

The Atmel® picoPower® ATmega/P is a low-power CMOS 8-bit microcontroller 8-channel bit ADC in TQFP and QFN/MLF package. •. Temperature. Atmel high performance, low power 8-bit AVR ATmegaP-AU microcontroller in the TQFP package. Okay, so I’m about to blow up. I’ve tried to use perhaps 10 Atmega TQFP without any success.

ATmega328P Microcontroller – TQFP

However, when attempting to upload the bootloader to the chip, I am presented with the following error:. Clearly I’m doing something incorrectly, and I wouldn’t doubt if it was because it’s not as simple as hooking the AVR programmer directly up to the chip to program it.

This question does not appear to be about electronics design within the scope defined in the help center. If this question can be reworded to fit the rules in the help centerplease edit the question. Well first of all, check the wiring.

Check that the ISP header connects to the pins that it ought to, and check that you have the chip oriented correctly in the socket The USBtiny has a switch to power the target, so make sure that’s in the correct position. If all that is correct, there are a couple other things that could cause that error:. The reset pin lacks the normal ESD protection, and so is fairly easy to fry.

Ground yourself and use an ESD mat. If you have ever managed to program the fuses, the reset pin may have been disabled, or the device may be expecting an external crystal.

If the reset pin has been disabled, you’ll need a special high voltage 12V programmer to recover it. Assuming your connection is incorrect, first you need to add a pull-up resistor to the reset pin; 1kk should be alright. That is pretty much all you need. Home Questions Tags Users Unanswered.

Any help would be appreciated. Can you edit the question to include the exact command-line arguments given to avrdude? It looks like the log text says ‘programmer operation not supported’, could be a symptom of bad cmd line args.

ATMega328 – TQFP

Have you applied power to the circuit? The AVR programmer will not supply power. TomCarpenter, the programmer does provide power.

It’s worth checking its in the correct position, though. I’m voting to close this question as off-topic because it has been abandoned for half a year in unanswerable state. If all that is correct, there are a couple other things that could cause that error: Crystal requirement atmea328 when booting through the bootloader i. When programming through SPI, the chip accepts the program even if the fuses are set to accept clock signal from external clock.

ISP requires a working clock source. Only HV programming does not. Atmega 2 9 Reset is driven by the programmer, and besides has an internal pullup.
