PLCC-52

Good day friends!

    I need help, Can anyone here suggest a 52pin PLCC that can replace an ATMEGA2560, I'm trying to make a PCB that would make changing of MCU easy. Unlike ATMEGA2560 which is really hard to troubleshoot.

Thanks and Regards,
Karl

You could make an adapter TQFP-64 to PLCC-52, Make it better PLCC-68 , it is a bit bigger

Thanks for the quick reply buddy! I've done that for testing, but now, is there a counterpart of ATMEGA2560, with regards to specs, that is a PLCC type?

No. PLCC packages are basically obsolete when it comes to modern ICs. If you look at Mouser, you will not find a single 16- or 32-bit microcontroller in this package. You will find some 8-bit µCs in PLCC, granddaddies like HC11s, 8051s, etc.; also some PICs. The only Atmel AVRs in PLCC are the ATmega8515 and ATmega8535.

I am not sure what the whole point is. Why do you want to a socket in the first place? Is this supposed to be a development board? There are QFP sockets; not cheap though... And desoldering a QFP part is also not rocket science these days.

If its to make it easy to change the MCU on a development board, put a SMD part on a daughter card, with any other support components it needs really close to it (e.g. decoupling).  You can also remap the connections to suit different MCU pinouts.

Go one step further: buy a pre-made module with 2.54mm spaced pins.
