  • Using C and I/O Pins to Interface 8051 MCUs with I2C(TM) Serial EEPROMs
    The 24XXX series serial EEPROMs from Microchip Technology support a bidirectional, 2-wire bus and data transmission protocol. The bus is controlled by the microcontroller (master), which generates the Serial Clock (SCL), controls the bus access and generates the Start and Stop conditions, while

  • Serial Communication with the SMBus
    ; I2C is a trademark of Philips Semiconductor. This application note describes configuration and operation of the SMBus. Example assembly and C code is given: (1) Interfacing a single EEPROM with 1-byte address space, in assembly; (2) Interfacing multiple EEPROMs with 2-byte address space, in C; and (3
