论述MC68HC705C8A与DS2430A 256位、1-

This application note describes the interface between the
MC68HC705C8A (C8A) and the DS2430A 1-Wire 256-bit EEPROM
from Dallas Semiconductor. The 1-Wire interface reduces the overhead
of control, data, address, and power pins found with other EEPROM
devices. One pin on the DS2430A combines all of these functions.
More embedded applications today are demanding non-volatile memory
storage. For instance, some applications in which EEPROM technology
is required are:
• Reprogrammable calibration data for test/measurement
equipment
• Power down information storage for consumer electronics like TVs
and VCRs
• Identification number storage for remote addressing or security
• Storage of telecommunication information such as phone number
recall and speed dialing
