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 input. When /CS is high the device is deselected and DO/IOx pins go to high impedance and current drops to standby. When /CS is low the device is selected and accepts instructions on DI/IOx. /CS must track VCC at power-up/down; a pull-up resistor is recommended. |+| 2 | DO (IO1) | bidirectional | Standard/Dual SPI serial data output; in Quad SPI mode (QE=1) this becomes bidirectional I/O bit 1 (IO1). Data is shifted out on the falling edge of CLK in standard SPI, or bidirectional on CLK edges for Dual/Quad I/O instructions. |+| 3 | /WP (IO2) | bidirectional | Active-low hardware Write Protect input for the Status Register (used with CMP/SEC/TB/BP2:0/SRP bits). Becomes bidirectional IO2 for Quad SPI instructions when QE=1 in Status Register-2. |+| 4 | GND | power_in | Device ground (0 V) reference. |+| 5 | DI (IO0) | bidirectional | Standard/Dual SPI serial data input; becomes bidirectional I/O bit 0 (IO0) for Dual/Quad SPI instructions. In Standard SPI, instructions/addresses/data are shifted in on the rising edge of CLK. |+| 6 | CLK | input | Serial Clock input. Provides timing for all serial input and output operations. SPI Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1) are supported, up to 133 MHz. |+| 7 | /HOLD or /RESET (IO3) | bidirectional | Active-low /HOLD (pauses SPI transactions while /CS remains low) or optional /RESET function in Standard/Dual SPI. In Quad SPI mode (QE=1) this pin becomes bidirectional IO3 and the /HOLD/ /RESET function is not available. |+| 8 | VCC | power_in | Device power supply, 2.7 V to 3.6 V. Typical power-down current <1 uA. /CS input must track VCC during power-up and power-down. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Winbond Elec |+| Package | SOIC-8-208mil |+| Category | Memory |+| Pins | 8 |++## Ordering variants++- `W25Q16JVSSIQSS`+- `W25Q16JVSSIQSSIQ`+- `W25Q16JVSSIQSSIG`+- `W25Q16JVSSIQSN`+- `W25Q16JVSSIQSNIQ`+- `W25Q16JVSSIQSNIG`+- `W25Q16JVSSIQZP`+- `W25Q16JVSSIQZPIQ`+- `W25Q16JVSSIQZPIG`+- `W25Q16JVSSIQUX`+- `W25Q16JVSSIQUXIQ`+- `W25Q16JVSSIQUXIG`+- `W25Q16JVSSIQUU`+- `W25Q16JVSSIQUUIQ`+- `W25Q16JVSSIQUUIG`+- `W25Q16JVSSIQXG`+- `W25Q16JVSSIQXGIQ`+- `W25Q16JVSSIQXGIG`+- `W25Q16JVSSIQBY`++## CAD (KiCad official)++- Symbol: `W25Q16JVSSIQ`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8-208mil (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Winbond Elec datasheet](docs/w25q16jvssiq-datasheet.pdf) (75 pp, sha256 `ebb56256faa02967`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
