CAT24C04YI-GT3A-TUDI from Tudi, in a TSSOP-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 | Per the datasheet, the A0 pin is no connect on the 4K device, which uses only A2 and A1 as device address bits. |
| 2 | A1 | input | Hard-wired device address input that must compare to its corresponding device address bit on the 4K device. |
| 3 | A2 | input | Hard-wired device address input that must compare to its corresponding device address bit on the 4K device. |
| 4 | GND | power_in | Ground reference for the device. |
| 5 | SDA | bidirectional | Open-drain serial data pin, normally pulled high by an external device, that may be wire-ORed with other open-drain or open-collector devices and changes only while SCL is low. |
| 6 | SCL | input | Serial clock input; data is clocked into the device on the SCL positive edge and out of the device on the negative edge. |
| 7 | WP | input | Hardware write protect: connect to GND for normal read/write operation, or to VCC to enable write protection of the full array. |
| 8 | VCC | power_in | Power supply, 1.7 V to 5.5 V. |
