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. Enables the device and frames each SPI transaction. Must be driven high between operations (tCS >= 100 ns). |+| 2 | SO | output | Serial Data Output. Clocks data out on the falling edge of SCK (SPI mode 0). High-Z when CS is high. |+| 3 | WP | input | Write Protect, active-low. When low and the WPEN bit in the status register is set, hardware-protects the status register and enabled memory blocks. |+| 4 | GND | power_in | Ground reference for the device. |+| 5 | SI | input | Serial Data Input. Opcodes, addresses, and write data are clocked in on the rising edge of SCK (SPI mode 0). |+| 6 | SCK | input | Serial Clock. Supports 0-20 MHz at 4.5-5.5V, 0-10 MHz at 2.5-5.5V, 0-5 MHz at 1.7-5.5V. Supports SPI modes 0 (0,0) and 3 (1,1). |+| 7 | HOLD | input | Hold input, active-low. Suspends serial communication without resetting the sequence; SO goes high-Z and SI/SCK are ignored while HOLD is low and CS is low. |+| 8 | VCC | power_in | Device power supply. Operating range 1.7V to 5.5V (absolute max 6.25V). Decouple with a 0.1 uF capacitor to GND close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Microchip |+| Package | SOIC-8 |+| Category | Memory |+| Pins | 8 |++## Ordering variants++- `AT25M01-SSHM-T`++## CAD (KiCad official)++- Symbol: `AT25M01-SSHM-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/at25m01-sshm-t-datasheet.pdf) (20 pp, sha256 `108635959b0d1a8d`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
