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 | NC | unconnected | No connect. Pin is not internally bonded and may be left floating or tied to VSS. |+| 2 | A1 | input | Device address input bit 1. Selects one of up to four CAT24M01 devices sharing the same I2C bus (combined with A2). Has an internal pull-down resistor; must match the corresponding bit of the slave address byte. |+| 3 | A2 | input | Device address input bit 2. Selects one of up to four CAT24M01 devices sharing the same I2C bus (combined with A1). Has an internal pull-down resistor; must match the corresponding bit of the slave address byte. |+| 4 | VSS | power_in | Ground reference for the device. Connect to system GND. |+| 5 | SDA | bidirectional | I2C serial data. Open-drain bidirectional data line; input data captured on rising edge of SCL, output data driven on falling edge of SCL. Requires external pull-up to VCC. Input capacitance up to 8 pF. |+| 6 | SCL | input | I2C serial clock input from the bus master. Supports Standard (100 kHz), Fast (400 kHz) and Fast-Plus (1 MHz) modes. Schmitt-trigger input with noise suppression filter. |+| 7 | WP | input | Write Protect. When driven HIGH, inhibits all write operations to the memory array; when LOW (or left floating), writes are enabled via the internal pull-down. Provides hardware write protection for the entire memory. |+| 8 | VCC | power_in | Positive supply, 1.8 V to 5.5 V. Read current up to 1 mA at fSCL = 1 MHz; write current up to 5 mA at VCC = 5.5 V; standby current typ. 2 uA. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | onsemi |+| Package | SOIC-8 |+| Category | Memory |+| Pins | 8 |++## Ordering variants++- `CAT24M01WI-GT3WI`+- `CAT24M01WI-GT3XI`+- `CAT24M01WI-GT3LI`+- `CAT24M01WI-GT3YI`+- `CAT24M01WI-GT3HU5I`++## CAD (KiCad official)++- Symbol: `CAT24M01WI-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/cat24m01wi-gt3-d.pdf) (14 pp, sha256 `913ea8e62a2ca346`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
