  • Using a Hardware Module to Interface 8051 MCUs with SPI Serial EEPROMs
    AN1197 Using a Hardware Module to Interface 8051 MCUs with SPI Serial EEPROMs The main features of the 25XXX serial EEPROMs are: Author: Alexandru Valeanu * SPI-compatible serial interface bus Microchip Technology Inc. * EEPROM densities from 128 bits to 512 Kbits * Bus speed from 3 MHz to 20 MHz
  • Interfacing 8051 MCUs with SPI Serial EEPROMs
    The 25XXX series serial EEPROMs from Microchip Technology support a half-duplex protocol that functions on a master-slave paradigm that is ideally suited to data stream applications. The bus is controlled by the microcontroller (master), which accesses the 25XXX serial EEPROM (slave) via a simple
  • Interfacing the 8051 with 2-wire Serial EEPROMs
    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
  • Using C and I/O Pins to Interface 8051 MCUs with I2C(TM) Serial EEPROMs
    is the hardware schematic depicting the interface between the Microchip 24XXX series of I2C serial EEPROMs and NXP's P89LPC952 8051-based MCU. The schematic shows the connections necessary between the MCU and the serial EEPROM as tested, as well as the required pull-up resistors on the clock line (SCL) and data
