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 HIGH or LOW to set the Slave address, allowing up to eight CAT24C64 devices to share the same I2C bus. Internally pulled LOW when left floating. |+| 2 | A1 | input | Device address input bit 1. Hard-wired HIGH or LOW to set the Slave address. Internally pulled LOW when left floating. |+| 3 | A2 | input | Device address input bit 2. Hard-wired HIGH or LOW to set the Slave address. Internally pulled LOW when left floating. |+| 4 | VSS | power_in | Ground reference for the device. |+| 5 | SDA | bidirectional | I2C Serial Data I/O. Open-drain in transmit mode; requires an external pull-up resistor to VCC. Data is acquired on the rising edge and delivered on the falling edge of SCL. |+| 6 | SCL | input | I2C Serial Clock input generated by the Master. Schmitt-triggered with noise suppression filter. |+| 7 | WP | input | Write Protect input. When held HIGH, all write operations to memory are inhibited. Internally pulled LOW when left floating, allowing writes. |+| 8 | VCC | power_in | Supply voltage input. Operating range 1.7 V to 5.5 V (Fast-Plus 1 MHz requires VCC >= 2.5 V). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | onsemi |+| Package | SOIC-8 |+| Category | Memory |+| Pins | 8 |++## Ordering variants++- `CAT24C64WI-GT3W`+- `CAT24C64WI-GT3X`+- `CAT24C64WI-GT3L`+- `CAT24C64WI-GT3Z`+- `CAT24C64WI-GT3Y`+- `CAT24C64WI-GT3US`+- `CAT24C64WI-GT3HU4`+- `CAT24C64WI-GT3VP2`+- `CAT24C64WI-GT3C4C`++## CAD (KiCad official)++- Symbol: `CAT24C64WI-GT3`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [onsemi datasheet](https://www.onsemi.com/pdf/datasheet/cat24c64wi-gt3-d.pdf) (17 pp, sha256 `0e4b6b61af47c300`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
