  • Page 8: Data Communication Between Cpu And Eeprom

    6-3. Data communication between CPU and EEPROM EEPROM Pin No.23 CS : Chip enable Pin No.14 SK : Sirial data clock BR93LC46A DI : Serial data input Pin No.15 DO : Serial data outpu Pin No.16 EEPROM is a memory to possible write/erase by electricity . The BR93LC46A privides efficient nonvolatile read/write memory arranged as 64 registers of 16 bits each.
  • Page 9 [Data reading procedure] When the CPU read the dara of EEPROM, CPU send the CS signal and SK signal to EEPROM. Then, CPU send the address to EEPROM, and then EEPROM send the data to CPU. Address Data Output data here [Data writing procedure] When the CPU save the data to EEPROM, CPU sends the CS and SK signal to EEPROM.
