ATMEGA64A PDF

HEX loading. I have selected the ATmega64 in device list but not able to connect to device is not reading device ID. ATmega64A is with default Setting of fuses. Its fresh chip. I have checked All connection.

I have developed a new P. Maybe I am missing something basic, but I am currently out of ideas. I'm confused by you programming header. The square pad usually denotes pin 1. Based on the power traces it appears rotated degrees. Read AVR Routing them out to some pads cost nothing except a bit of time and can make modifications a lot easier. A lot of wire's are going directly from the uC to connectors. Leaving inputs of an opamp U3 open is bad practice and can lead to oscillations and nasty stuff.

Besides of programming pins. I also emphasis ground plane, bypass cap as close as possible for U1, U4 Heat sink for U4 pad 2 protection diodes for U4. Your routing and branching tracks generally nice. Thank You Kabasan and Balisong24, it worked like a charm. Apart from your programming problem a few remarks on pcb design:. Thank you for the feedback Paulvdh and M. Majid, this is just what I need, will have a look into it and design another one probably.

Ground planes help a lot in making a desing more robust. The 2 dip14 ic's have decoupling caps, but I se no on you uC. You have quite a lot of unused pins on you uC. I think U4 is an smd voltage regulator. These SMD's are small enough as they come and overheat easily. Usually these are given a big piece of copper trace to provide some cooling.

Look in the datasheet of your opamp on how to "passivate" unused opamps. If the opamp is unity-gain stable a 1x buffer with the other input to a known signal is ok. Posted by m. Jan 27, - AM.
