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 | NC | unconnected | No Connect. On the AT24C04C the A0 line is not used for addressing; this pin is a no-connect and may be tied to GND. |+| 2 | A1 | input | Hardware address input A1 (used on AT24C04C only, allows up to four 4K devices on one I2C bus). Static CMOS input; tie to VCC or GND. On the AT24C08C variant this pin is a no-connect. |+| 3 | A2 | input | Hardware address input A2. Static CMOS input, tied to VCC or GND to set the slave address of the device for multi-device bus systems. |+| 4 | GND | power_in | Ground reference for the device (0 V). |+| 5 | SDA | bidirectional | I2C serial data. Bidirectional, open-drain; requires an external pull-up resistor. May be wire-ORed with other open-drain/open-collector devices on the bus. |+| 6 | SCL | input | I2C serial clock input. Positive edge clocks data into and negative edge clocks data out of the device. Up to 400 kHz at 1.7 V, up to 1 MHz at 2.5/2.7/5.0 V. |+| 7 | WP | input | Write Protect. Active-high hardware write protect: tie to VCC to protect the entire array, tie to GND for normal read/write operations. |+| 8 | VCC | power_in | Power supply input, 1.7 V to 5.5 V. Typical ICC = 0.4 mA read / 2.0 mA write at 5.0 V, 100 kHz; standby currents 1.0 uA (1.7 V) / 6.0 uA (5.5 V). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Microchip |+| Package | SOIC-8 |+| Category | Memory |+| Pins | 8 |++## Ordering variants++- `AT24C04C-SSHM-TSSHM-T`+- `AT24C04C-SSHM-TSSHM`+- `AT24C04C-SSHM-TPU`+- `AT24C04C-SSHM-TXHM`+- `AT24C04C-SSHM-TMAHM`+- `AT24C04C-SSHM-TDW`+- `AT24C04C-SSHM-TCM`++## CAD (KiCad official)++- Symbol: `AT24C04C-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/at24c04c-sshm-t-datasheet.pdf) (24 pp, sha256 `fddea59c963fc82a`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
