28 pin microcontroller
Hi all,
I got an assignment to develop program for a 28-pin DIP type package microcontroller. The hardware is already designed and assembled but the microcontroller is damaged.
The number on microcontroller has been scraped off. Only info about microcontroller I could extract by tracing the PCB is as follows:
Pin 28 - Supply (+5V)
Pin 14 - Ground (supply -ve)
Pin 19 - Ground (supply -ve)
Pin 21 - Analog Input
Please can anyone help me identify the microcontroller!
Thanks in advance for any help.
