This is a simple circuit for programming the 28C16, 28C64, 28C256, and similar parallel EEPROMs using an Arduino. Since the Arduino doesn’t have enough pins to directly control all of the address, ...

The SN74LV8153 is a serial-to-parallel IC. It can translate serial (yes, UART) to 8 parallel output pins. In combination with a USB-to-serial converter this is a very powerful, yet simple setup to ...

Behold this ATtiny85 based EEPROM programmer. It seems like a roundabout way of doing things, but [Quinn Dunki] wanted to build to her specifications using tools she had on hand. What she came up with ...

Over on YouTube [Electronic Wizard] explains how to use the AT24C32 EEPROM for external memory for microcontrollers. He begins by explaining that you don’t want to ...
