"C" version? you mean PIC16C73A... the C in bold? or issit something else? i didn't know that so thanks.
My problem is when i access the online catalogue there're the following versions of of the same PIC for example:
PIC16C73A-10/SO - IC, SM 8-BIT CMOS MCU
PIC16C73A-20I/SO - IC, SM 8-BIT CMOS MCU
PIC16C73A-04SP - IC, 8-BIT CMOS MCU
PIC16C73A-20SO - IC, SM 8-BIT CMOS MCU
PIC16C73A-10SP - IC, 8-BIT CMOS MCU
PIC16C73A-04ISP - IC, 8-BIT CMOS MCU
and a couple others all with different extensions at the back. I've checked the datasheets but they all shared the same one. How do I know which is applicable to my application and what do the extensions mean? hope someone can help clarify
