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 | Chip Select (active-low). When high the device is deselected and SO is high-impedance; must be driven low to start any read or write command. Input capacitance ~8 pF. |+| 2 | SO | output | Serial Data Output. Data is shifted out MSB-first on the falling edge of SCK (SPI mode 0,0 or 1,1). Output capacitance ~8 pF; high-Z when CS is high or HOLD is asserted. |+| 3 | WP | input | Write Protect (active-low). When driven low and the WPEN bit is set, non-volatile status register writes and array writes are inhibited. Provides hardware write protection. |+| 4 | VSS | power_in | Ground reference for the device. |+| 5 | SI | input | Serial Data Input. Opcode, address and data are latched on the rising edge of SCK, MSB-first. Input capacitance ~8 pF. |+| 6 | SCK | input | Serial Clock. Supports SPI modes (0,0) and (1,1). Max 20 MHz at VCC = 4.5-5.5 V, 10 MHz at VCC >= 2.5 V, 5 MHz at VCC >= 1.8 V. |+| 7 | HOLD | input | Hold Transmission Input (active-low). Pausing SPI communication without deselecting the device; SO goes high-impedance and SI/SCK are ignored while HOLD is low. |+| 8 | VCC | power_in | Positive supply. Operating range 1.8 V to 5.5 V. Absolute max pin voltage VCC + 0.5 V (6.5 V max). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | onsemi |+| Package | SOIC-8 |+| Category | Memory |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `CAT25640VI-GT3`+- `CAT25640VI-GT3V`+- `CAT25640VI-GT3L`+- `CAT25640VI-GT3Y`+- `CAT25640VI-GT3HU4`+- `CAT25640VI-GT3HU3`+- `CAT25640VI-GT3VP2`++## CAD (KiCad official)++- Symbol: `CAT25640VI-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/cat25640vi-gt3-d.pdf) (19 pp, sha256 `66fe9e8a3e8b3ff2`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
