AT24C16C-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 | unconnected | Datasheet pin description lists A0 as a hardwired device address input, but the device addressing section states that for the 16K device the A0, A1 and A2 pins are no connect. |
| 2 | A1 | unconnected | Datasheet pin description lists A1 as a hardwired device address input, but the device addressing section states that for the 16K device the A0, A1 and A2 pins are no connect. |
| 3 | A2 | unconnected | Datasheet pin description lists A2 as a hardwired device address input, but the device addressing section states that for the 16K device the A0, A1 and A2 pins are no connect. |
| 4 | GND | power_in | Ground reference for the device. |
| 5 | SDA | bidirectional | Bi-directional serial data pin; open-drain driven and may be wire-ORed with other open-drain or open-collector devices, and it is normally pulled high by an external device. |
| 6 | SCL | input | Serial clock input: data is clocked into the device on the positive edge and out of the device on the negative edge of SCL. |
| 7 | WP | input | Write Protect pin: connected to GND allows normal read/write operations, while connected to VCC enables write protection of the full array. |
| 8 | VCC | power_in | Power supply, specified from 1.7 V to 5.5 V for the device. |
