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 | unconnected | Not connected internally on the 24XX04. May be left floating or tied to VSS or VCC. Present for pin compatibility with larger 24-series EEPROMs. |+| 2 | A1 | unconnected | Not connected internally on the 24XX04. May be left floating or tied to VSS or VCC. Present for pin compatibility with larger 24-series EEPROMs. |+| 3 | A2 | unconnected | Not connected internally on the 24XX04. May be left floating or tied to VSS or VCC. Present for pin compatibility with larger 24-series EEPROMs. |+| 4 | VSS | power_in | Ground reference for the device (0 V). |+| 5 | SDA | bidirectional | Serial Address/Data I/O. Bidirectional open-drain line for the I2C bus; requires an external pull-up to VCC (typical 10 kΩ for 100 kHz, 2 kΩ for 400 kHz/1 MHz). Data may only change while SCL is low. |+| 6 | SCL | input | Serial Clock input used to synchronize data transfer to and from the device. Driven by the I2C master; the 24XX04 operates as an I2C slave. |+| 7 | WP | input | Write-Protect input. Must be connected to either VSS or VCC. Tied to VSS: normal read/write operation (memory 000-1FF writable). Tied to VCC: entire memory is write-protected; reads are unaffected. |+| 8 | VCC | power_in | Power supply input. Operating range 2.5 V to 5.5 V for the 24LC04B; absolute maximum 6.5 V. Standby current 1 µA typical, active current 1 mA maximum. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Microchip |+| Package | SOIC-8 |+| Category | Memory |+| Pins | 8 |++## Ordering variants++- `24LC04BT-ISN`+- `24LC04BT-IP`+- `24LC04BT-IMS`+- `24LC04BT-IST`+- `24LC04BT-IMC`+- `24LC04BT-IMNY`+- `24LC04BT-IMUY`+- `24LC04BT-IOT`+- `24LC04BT-ICSP`++## CAD (KiCad official)++- Symbol: `24LC04BT-I`+- 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/24lc04bt-i-datasheet.pdf) (46 pp, sha256 `40bb9334fc46dd10`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
