     APPLICATION #6 Serial I2C EEPROM 2416 interfacing  

The circuit below shows how to interface a Serial I2C EEPROM, namely the 2402 to a PIC16F84 via a simple 2 wire interface ! In addition, the circuit has a MAX232 IC for the Voltage level shifting so that it can be connected to a serial COM port( RS-232C ) of a PC.

Low Cost PIC C Compilers ?                   PCM C from CCS, USA ~US$99  


The following code, ex_extee.c and 2402.c demonstrate how to uses the 2402 external EEPROM to read and write to an external serial EEPROM and then display out the results via an RS-232 terminal program running on a PC.
