Tester for 4116/4164/41256 or compatible DRAM chip
This project is based on 4116 Tester developed by uffe@frostbox-net.
Original project could be found at: https://labs.frostbox.net/2020/03/24/4116-d-ram-tester-with-schematics-and-code/
This version was added following new features:
- 4164/41256 or compatible support
- OLED display
- Serial output port
- In 4164/41256 mode, auto detect 4164 chip
- Chinese UI support
You can use Arduino IDE to compile and upload the code to ATMEGA328p MCU.
You may check the Schematic PNG file in repository for detail.
BOM List:
You should chose the CORRECT model via SW1 switch BEFORE you put the chip into the ZIFF socket.
Or, it will DAMAGE the chip for the wrong voltage settings!!!
