Pinout
5Low source legibility.The original manufacturer datasheet for this part was difficult to read, so this pinout may be incomplete or imperfect. Always confirm against the specific manufacturer’s datasheet before wiring.
| Pin | Name | Functions | Notes |
|---|---|---|---|
| CHIP_ENABLE | Chip Enable | GPIO | Turns off the device when high. |
| ADDRESS_LINES | Address Lines | GPIO | Standard TTL-compatible inputs for addressing 16 words. |
| DATA_IN_LINES | Data In Lines | GPIO | Inputs data to be written into memory cells. |
| WRITE_ENABLE | Write Enable | GPIO | Gates the data on the data input leads into the memory cells. |
| DATA_OUT_LINES | Data Out Lines | GPIO | Outputs the complement of Data In when writing, and can be wire-ORed with other outputs. |
