CAT24C256WI-GT3-TUDI
Tudi · EEPROM · SOP-8
CAT24C256WI-GT3-TUDI from Tudi, in a SOP-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 | Device address input that selects one of up to 8 devices on the bus, with an on-chip pull-down resistor. |
| 2 | A1 | input | Device address input that selects one of up to 8 devices on the bus, with an on-chip pull-down resistor. |
| 3 | A2 | input | Device address input that selects one of up to 8 devices on the bus, with an on-chip pull-down resistor. |
| 4 | VSS | power_in | Ground reference for the supply. |
| 5 | SDA | bidirectional | Serial data I/O pin that receives input data and transmits stored data, open drain in transmit mode and pulled up to VCC externally. |
| 6 | SCL | input | Serial clock input that accepts the clock signal generated by the I2C master, with Schmitt trigger and noise suppression filter. |
| 7 | WP | input | Write protect input that inhibits all write operations to the entire memory when pulled HIGH, with an on-chip pull-down resistor. |
| 8 | VCC | power_in | Power supply pin for a supply voltage range of 1.8 V to 5.5 V. |
