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 | CS | input | Active-low chip select. Every SPI transaction must begin with a HIGH-to-LOW transition on CS and end with a LOW-to-HIGH transition. When CS is HIGH the device is in Standby Mode and SO is tri-stated. |+| 2 | SO | output | Serial data output. Data is shifted out on the falling edge of SCK in SPI modes (0,0) and (1,1). Output is high-impedance when CS is HIGH or HOLD is asserted low. |+| 3 | WP | input | Active-low write protect. When WP is held low and the WPEN bit in the Status Register is 1, writing to the Status Register is disabled (hardware write protection). |+| 4 | VSS | power_in | Ground reference for supply and I/O. |+| 5 | SI | input | Serial data input. Accepts op-codes, addresses, and write data. Data is latched on the rising edge of SCK in SPI modes (0,0) and (1,1). |+| 6 | SCK | input | Serial clock input, provided by the SPI host to synchronize communication. Supports DC to 20 MHz depending on VCC. |+| 7 | HOLD | input | Active-low hold input used to pause an SPI transmission without dropping CS. Taking HOLD low freezes the interface; taking it high resumes with SCK low during both transitions. Tie to VCC (directly or via a pull-up) when not used. |+| 8 | VCC | power_in | Positive supply, 1.8 V to 5.5 V. Read supply current up to 3 mA at 20 MHz; write supply current up to 2 mA. Standby current typically <5 uA. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | onsemi |+| Package | SOIC-8 |+| Category | Memory |+| Pins | 8 |++## Ordering variants++- `CAT25512VI-GT3`+- `CAT25512VI-GT3XI`+- `CAT25512VI-GT3LI`+- `CAT25512VI-GT3YI`+- `CAT25512VI-GT3HU5`+- `CAT25512VI-GT3C8A`++## CAD (KiCad official)++- Symbol: `CAT25512VI-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/cat25512vi-gt3-d.pdf) (17 pp, sha256 `ff68b0f40b13b7de`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
