Hi! I've a microcontroller board on which the micontroller's identification was sanded and I would like to identify it. The microcontroller's case is a TQFP44 or LQFP44. Analysing the PCB's electrical links, I see that : The crystal, whose rated frequency is 11.0592 MHz, is attached to pins 30 and 31 of the microcontroller. The microcontroller is powered with +5V ( pin 7 or 28 ) and GND ( pin 6 or 29 ) It has an I2C interface at pins 37 ( SCL ) and 42 ( SDA ). The PCB has a spare connector, which I think is used for programming the chip on board, whose pins are connected to pins 14, 15, 16, 17 and 18 of the microcontroller. Any help will be much appreciated. Thanks in advance.
You may want to take a look at Microchips PIC18F series. The PIC18F4680 uses those pins in the role you described. It likely won't be the only one from Microchip though.
Yes, you're right ! Thank you very much.
