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, overbar in datasheet). Enables the device; must transition high-to-low to start a command and low-to-high to end it. When high, SO is tri-stated and the device is in Standby. |+| 2 | SO | output | Serial Data Output (MISO). Shifts data out on the falling edge of SCK. Tri-stated when CS is high. |+| 3 | WP | input | Write Protect (active-low). When WP is low and the WPEN bit in the Status Register is 1, writes to the Status Register are disabled (hardware write protection). |+| 4 | VSS | power_in | Ground reference for the device. |+| 5 | SI | input | Serial Data Input (MOSI). Accepts op-codes, addresses, and data; latched on the rising edge of SCK in SPI modes (0,0) and (1,1). |+| 6 | SCK | input | Serial Clock input from the SPI host. Synchronizes communication between the host and CAV25256. Maximum 10 MHz at VCC = 5 V. |+| 7 | HOLD | input | Hold Transmission Input (active-low). Pauses an in-progress SPI transaction without terminating it; drive HOLD low with SCK low to pause, and back high with SCK low to resume. Tie to VCC directly or via a resistor when unused. |+| 8 | VCC | power_in | Positive supply voltage, 2.5 V to 5.5 V operating range. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | onsemi |+| Package | SOIC-8 |+| Category | Memory |+| Pins | 8 |++## Ordering variants++- `CAV25256VE-GT3V`+- `CAV25256VE-GT3`+- `CAV25256VE-GT3Y`+- `CAV25256VE-GT3C8A`++## CAD (KiCad official)++- Symbol: `CAV25256VE-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/cav25256ve-gt3-d.pdf) (15 pp, sha256 `a765644f464c3e5b`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
