The heart of the EEPROM programmer is an ATmega8 microcontroller. The address bus of the EEPROM (up to 15 bit) is controlled via two daisy-chained 74HC595 shift registers using hardware SPI @ 8 Mbps.

I am building an 8 bit computer, and for this computer I designed 8 bit instructions, each of which can have up to 8 microcode steps. I defined up to 24 control signals (thus needing 3 bytes per step ...

In this tutorial we will learn how easy it is to save data using the EEPROM present in the PIC16F877A Microcontroller. In most real time projects we might have to save some data which should not be ...

Almost all AVR microcontrollers have built-in Electrically Eraseable Programmable Read Only Memory (EEPROM).The advantage of EEPROM is that even when the microcontroller is turned off, data stored in ...
