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 | A0 | input | Device address input bit 0. Hard-wired to VCC or GND to set one of eight I2C slave addresses (0xA0..0xAE); compared against the A0 bit of the device-address byte before the EEPROM acknowledges. High-impedance input, VIL <= 0.3*VCC, VIH >= 0.7*VCC. |+| 2 | A1 | input | Device address input bit 1. Hard-wired to VCC or GND to select the slave address; compared against the A1 bit of the device-address byte. Input capacitance ~6 pF. |+| 3 | A2 | input | Device address input bit 2. Hard-wired to VCC or GND to select the slave address; compared against the A2 bit of the device-address byte. Input capacitance ~6 pF. |+| 4 | GND | power_in | Ground reference (0 V) for the device. |+| 5 | SDA | bidirectional | I2C serial data. Bidirectional, open-drain; requires an external pull-up to VCC. May be wire-ORed with other open-drain/open-collector devices. Schmitt-trigger input with noise filtering. VOL <= 0.4 V at IOL = 2.1 mA (VCC = 3.0V). |+| 6 | SCL | input | I2C serial clock input. Positive-edge clocks data into the EEPROM and negative-edge clocks data out. Schmitt-trigger, filtered input. Supports up to 400 kHz at 1.7V and 1 MHz at 2.5V/2.7V/5.0V. |+| 7 | WP | input | Write Protect. Tie to GND for normal read/write; tie to VCC to hardware-protect the full array against writes (per Table 4-1). No internal pull-up/down - must be driven. |+| 8 | VCC | power_in | Supply voltage. Operating range 1.7 V to 5.5 V. ICC ~1.0 mA (read at 400 kHz, 5.0V), ~3.0 mA (write at 400 kHz, 5.0V); standby current 1.0/2.0/6.0 uA at 1.7/2.5/5.5 V. A local 0.1 uF decoupling capacitor to GND is recommended. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Microchip |+| Package | SOIC-8 |+| Category | Memory |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `AT24C01C-SSHM-T`++## CAD (KiCad official)++- Symbol: `AT24C01C-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/at24c01c-sshm-t-datasheet.pdf) (23 pp, sha256 `354e804e869397e1`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
