AT24C01D-PUM-TUDI from Tudi, in a DIP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A0 | input | Address input (hardwired device address bit A0) that lets up to eight devices share one bus, biased to logic low internally if left floating. |
| 2 | A1 | input | Address input (hardwired device address bit A1) that lets up to eight devices share one bus, biased to logic low internally if left floating. |
| 3 | A2 | input | Address input (hardwired device address bit A2) that lets up to eight devices share one bus, biased to logic low internally if left floating. |
| 4 | GND | power_in | Ground; also the connection for WP that allows normal read/write operations. |
| 5 | SDA | bidirectional | Bidirectional serial data pin, open-drain driven, may be wire-ORed with other open-drain or open-collector devices and needs an external pull-up. |
| 6 | SCL | input | Serial clock input that clocks data into the EEPROM on the positive edge and out on the negative edge. |
| 7 | WP | input | Write protect input; connected to GND allows normal read/write operations, connected to VCC write-protects the full array. |
| 8 | VCC | power_in | Power supply, 1.7V to 5.5V at 400kHz (2.5V to 5.5V at 1MHz); absolute maximum -0.3V to +6.5V. |
