Just got the replacement RAM from ali - https://he.aliexpress.com/item/1005008068111259.html, and going to make thr RAM tester with ESP32,
ESP32 to TMS4164 Pin Mapping
Configure your pins in the Arduino IDE according to this map or modify the definitions in the code below.
| TMS4164 Pin | Function | ESP32 GPIO |
|---|---|---|
| Pin 8 | VCC (+5V) | External 5V Supply |
| Pin 16 | VSS (GND) | GND (Commoned with ESP32) |
| Pin 4 | RAS (Row Address Strobe) | GPIO 23 |
| Pin 15 | CAS (Column Address Strobe) | GPIO 22 |
| Pin 3 | W (Write Enable) | GPIO 21 |
| Pin 2 | D (Data In) | GPIO 19 |
| Pin 14 | Q (Data Out) | GPIO 18 (Use Voltage Divider) |
| Pins 5,6,7,12,11,10,13,9 | A0 – A7 (Address Bus) | GPIOs 13, 12, 14, 27, 26, 25, 33, 3 |
