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 SPI Chip Select. A high-to-low transition on CS selects the device and initiates a new instruction sequence; a low-to-high transition deselects it and forces the SO output to high-impedance. Must be held high during standby to minimize supply current. |+| 2 | SO | output | Serial Data Output. Data is shifted out on the falling edge of SCK (MSB first). High-impedance when CS is high or when the device is in HOLD. |+| 3 | WP | input | Active-low Write Protect. When held low together with the WPEN bit in the status register set, the status register is hardware write-protected, preventing changes to the block protection bits. Tie to VCC if unused. |+| 4 | VSS | power_in | Ground reference for all supply and signal levels (0 V). |+| 5 | SI | input | Serial Data Input. Op-codes, addresses and data are shifted in on the rising edge of SCK (MSB first). |+| 6 | SCK | input | SPI Serial Clock input. Supports SPI modes (0,0) and (1,1) up to 20 MHz at VCC >= 4.5 V (10 MHz at VCC >= 2.5 V, 5 MHz at VCC < 2.5 V). |+| 7 | HOLD | input | Active-low Hold input. Pausing serial communication without deselecting the device; when low (with CS low) SO goes high-Z and SI/SCK are ignored. Tie to VCC if unused. |+| 8 | VCC | power_in | Positive supply voltage, 1.8 V to 5.5 V. Typical read current 0.8-3.0 mA depending on VCC/frequency; standby current 1-5 uA. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | onsemi |+| Package | SOIC-8 |+| Category | Memory |+| Pins | 8 |++## Ordering variants++- `CAT25256VI-GT3`+- `CAT25256VI-GT3VE-GT3`+- `CAT25256VI-GT3LI-G`+- `CAT25256VI-GT3XI-T2`+- `CAT25256VI-GT3XE-T2`+- `CAT25256VI-GT3YI-G`+- `CAT25256VI-GT3YI-GT3`+- `CAT25256VI-GT3HU4I-GT3`++## CAD (KiCad official)++- Symbol: `CAT25256VI-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/cat25256vi-gt3-d.pdf) (18 pp, sha256 `15c84e62f165bfbe`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
