If you have already decided to buy a programmer, then the SPI/I2C/1W DIP24 socket is what is commonly called a "must-have" adapter. With this universal adapter, the programmer can be turned into a tool for working with different types of memory, protocols and voltages. By choosing the desired operating mode, it is possible to work with SPI NOR, SPI NAND, SPI EEPROM, I2C EEPROM, Microwire (3-Wire) EEPROM and 1-Wire devices.
