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 | SPI Chip Select, active-low. A high-to-low transition enables the device; a low-to-high transition ends the current instruction and puts the SO output into high-impedance. |+| 2 | SO | output | Serial Data Output. Data is shifted out on the falling edge of SCK; high-impedance when CS is deasserted. |+| 3 | WP | input | Write Protect, active-low. When low, all write operations to the status register are inhibited, providing hardware protection of the block-protection bits. |+| 4 | GND | power_in | Ground reference for the device supply and all I/O signals. |+| 5 | SI | input | Serial Data Input. Instructions, addresses, and data are shifted in on the rising edge of SCK, MSB first. |+| 6 | SCK | input | Serial Clock. Provides the timing reference for SPI transfers. Supports up to 20 MHz at VCC = 4.5-5.5 V, 10 MHz at 2.5-5.5 V, and 5 MHz at 1.8-5.5 V. |+| 7 | HOLD | input | Suspends serial input, active-low. When low with CS also low, the current SPI operation is paused without resetting the serial sequence; SO goes high-impedance and SI/SCK are ignored. |+| 8 | VCC | power_in | Positive supply voltage, 1.8 V to 5.5 V. Typical supply current is 7.5 mA read / 4.0 mA read+write at 5 V, 20 MHz; standby current is <0.1 uA at 1.8 V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Microchip |+| Package | SOIC-8 |+| Category | Memory |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `AT25080B-SSHL-T`+- `AT25080B-SSHL-TXHL`+- `AT25080B-SSHL-TMHL`++## CAD (KiCad official)++- Symbol: `AT25080B-SSHL-T`+- 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:** [Microchip datasheet](docs/at25080b-sshl-t-datasheet.pdf) (25 pp, sha256 `4c31815840054a16`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
