# CAT24C01WI-GT3-TUDI

**Tudi** · EEPROM · SOP-8

CAT24C01WI-GT3-TUDI from Tudi, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A0 | input | Device address input bit 0. Hard-wired to VCC or GND to set the chip's I2C slave address, allowing up to 8 devices on a single 2-wire bus. |
| 2 | A1 | input | Device address input bit 1. Hard-wired to VCC or GND to set the chip's I2C slave address. |
| 3 | A2 | input | Device address input bit 2. Hard-wired to VCC or GND to set the chip's I2C slave address. |
| 4 | GND | power_in | Ground reference (0 V) for the device. |
| 5 | SDA | bidirectional | I2C serial data line. Open-drain bidirectional pin; requires an external pull-up resistor to VCC. May be wire-ORed with any number of other open-drain or open-collector devices. |
| 6 | SCL | input | I2C serial clock input. Positive edge clocks data into the EEPROM, negative edge clocks data out. Requires an external pull-up resistor. |
| 7 | WP | input | Write Protect input. Tie to GND for normal read/write operations; tie to VCC to enable hardware write-protect of the full array. |
| 8 | VCC | power_in | Positive supply voltage input. Operating range 1.7 V to 5.5 V (WI variant compatible down to 1.8 V). |
