A text editor Project:
I want it to read ASCII text (7 bit)from an general EEPROM of I²C bus. I'll be plugging a 24C08 with preloaded text, and it will read/write the text there. Then the MCU will simply transfer the text to a 2x16 (serial) LCD (that one we use mostly).
I have a 8051 MCU P80C31 and also a 8052 MCU SM8952A. Which one can be used for this? I want to run it with 6Mhz clock.
I chosen these MPU as these have 4x 8bit ports. I want to use one or two 8bit ports as a keyboard matrix for entering text in write mode and the other one port will control the LCD and EEPROM and the last port will be used for control keys for UI.

I have edited my question now as you gave reference of 8051 but my MPU was 8052. I have 8051 MPU too.
Hope I have described my project clearly. It's a text editor. But if I can do just upto text reader part (eeprom to MPU to 16x2lcd) that will also be great.
 

Dear my friend 8051 or 8052 is the same the difference at the size of internal ram memory size and internal code memory size
 

I'll reply after a few days after I do some experiments.
