AN1096, Using the C30 Compiler to Interface SPI Serial EEPROMs

AN1096 Using the C30 Compiler to Interface SPI Serial EEPROMs with dsPIC33F and PIC24F Author: Martin Kvasnicka Microchip Technology Inc.

This application note provides assistance and source code to ease the design process of interfacing a Microchip dsPIC33F Digital Signal Controller to a Microchip SPI serial EEPROM, without the use of a hardware serial port.

Figure 1 describes the hardware schematic for the interface between Microchip’s 25XXX series devices and the dsPIC33F DSC or PIC24F PIC® m

AN1096 Features

* are not used in the examples provided. INTRODUCTION The 25XXX series serial EEPROMs from Microchip Technology are SPI compatible and have maximum clock frequencies ranging from 3 MHz to 20 MHz. Many times when designing an application which utilizes a serial EEPROM device, it may be beneficial to u
