8051接口的2线串行EEPROM

Many designers today are implementing embedded
systems that require low cost non-volatile memory.
Microchip has addressed this need with a full line of
serial EEPROMs, in a variety of memory
configurations, using the industry-standard 2 or 3-wire
communication protocols. The theory and application
of these protocols are addressed in detail in
Microchip’s application note AN536.
