With four pins, you can also use EEPROM memory with SPI interface. If you don't have hardware support for the I2C interface, then it is much easier to implement SPI communication in software than it is to implement I2C. In my humble opinion, it is equally simple to implement an I2C bit-banged single-master with no clock stretching at the slave side (which is the case with these memories), as is the SPI counterpart. Speaking from experience - done both as a '51 novice back then. JW |
