Post as a guest Name. I hope we can offer you a warm welcome, but your question might be a dupe. Buy from the Microchip Store. But, this is a different chip slightlydifferent fuse settings, and a different programmer, so I say we let it stand And I don’t have the rep to flag it.

For pricing and availability, contact Microchip Local Sales. Calibration of the internal RC oscillator. This is nice and low power, but it means that your programmer likely isn’t clocking itself slowly enough to program your device.

The chip would no longer communicate. In addition the Power Debugger has two independent current sensing channels for measuring and optimizing the power consumption of.

First, welcome to the site! And finally, What can I do to rescue my chip? Sign up using Facebook. Could it be that using avrdude’s definition for the P version of the chip rather than the PA version is the cause? Algorithm Builder for AVR. Conditional Assembly and portability macros.


Sign up using Email and Password. Upgrading the Flash memory using a U-Disk. Thanks for that fuse calculator link, a great resource indeed. The device operates between 1. By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and processing speed. It’s fantastic that you read the datasheet, and tried to calculate what you wanted yourself, but the tool makes it much easier.

Well until I decided to change some fuses. Please contact sales office if device weight is not available. Sign up or log in Sign up using Google. Email Required, but never shown. Atmel-Integrating the Internet of Things.

Nope, your 0x63 setting on the lfuse byte has selected the internal kHz oscillator as the clock source. Runtime calibration and compensation of RC oscillators.

Enhancing ADC resolution by oversampling. Next time, this fuse setting calculator is a nice resource. BTW, what were the fuses set to before you made the change? There’s also one here on Chiphacker see my comment. Application Notes Download All.


Any ideas as to why the chip is unresponsive? As I’ve never used the device, I’ll defer to the many other threads where others have posted problems and atmgea644pa for AVR fuse settings.

I’m not familiar with either avrdude or the STK, but this is where your problem is coming from. Only show products with samples. A complete starter kit and development system for the 8-bit and bit AVR microcontrollers that gives designers a quick start to develop code on the AVR, with advanced features for prototyping and testing new atmega644p.
