#160303 - AT89C51RD2 Pin Compatibility with 80C51
Hi ,
I'm having one board which has 80C51 (44 Pin PLCC) microcontroller and it executes code from external EEPROM.I want want to change the microcontroller to AT89C51RD2 (44 Pin PLCC) . I want to know whether AT89C51RD2 (44 Pin PLCC) is Pin and code compatible with 80C51 (44 Pin PLCC).

I went through the data sheet of AT89C51RD2 which says it is
• 80C52 Compatible
– 8051 Instruction Compatible

Does it mean it is code compatible with 80C51 but not pin compatible ?


Thanks
Sanjay
