Arduino EEPROM Programmer (28C16)

A custom PCB shield and Arduino firmware designed to program 28C16 Parallel EEPROMs.

This tool is essential for projects like the Ben Eater 8-bit computer, allowing you to burn microcode or 7-segment display logic into non-volatile memory without manually toggling dip switches.

🔌 Hardware Design (KiCad)

The gerbers/ and root directory contain the full design files for a custom PCB that fits on top of an Arduino (or connects via headers).

Chip Support: 28C16 (2K x 8-bit Parallel EEPROM).
Design Tool: KiCad (Schematic & PCB files included).
Status: Production-ready Gerber files are available in the gerbers folder.

💻 Firmware (Arduino)

The C++ code in arduino_programmer/ handles the write cycle timing and address management.

Key Features

Write Cycle Control: Manages the Write Enable (WE) and Chip Enable (CE) pulses required by the 28C16 datasheet.
7-Segment Decoding: By default, the code includes a lookup table to program the EEPROM with hexadecimal digits (0-9) for a common-cathode 7-segment display.
Customizable: You can modify the data array to burn any microcode instruction set.

🚀 Getting Started

1. Fabrication / Wiring

You can either:

Order the PCB: upload the zip gerber files to a PCB manufacturer (JLCPCB, PCBWay, etc.).
Breadboard it: Follow the pinout defined in the arduino_programmer.ino file to wire the EEPROM directly to the Arduino digital pins.
