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. Not internally bonded; may be left floating. |+| 2 | A1 | input | Device address input bit 1. Hardwired to VIH or VIL to set the chip's I2C device address (matched against the 5th/6th device-address bits). Floating pins are internally recognized as VIL; a pull-up/pull-down of 10 kOhm or less is recommended. |+| 3 | A2 | input | Device address input bit 2. Hardwired to VIH or VIL to set the chip's I2C device address. Floating pins default to VIL internally; recommended pull-up/down 10 kOhm or less. |+| 4 | GND | power_in | Device ground reference (0 V). |+| 5 | SDA | bidirectional | Serial data line. Bidirectional open-drain I/O for the 2-wire (I2C-compatible) bus. Requires an external pull-up resistor; can be wire-ORed with other open-drain devices. |+| 6 | SCL | input | Serial clock input. Rising edge latches data into the EEPROM; falling edge clocks data out. Schmitt-triggered filtered input; supports 1 MHz (2.5-5V) or 400 kHz (1.8V). |+| 7 | WP | input | Write protect. Tie to VIL (or leave floating) to allow programming; tie to VIH or VCC to disable all programming operations. Read operations are unaffected. Recommended pull-up/down 10 kOhm or less. |+| 8 | VCC | power_in | Positive supply. 1.8 V to 5.5 V (industrial temperature range -40 C to 85 C). Standby current typically < 1 uA. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | XBLW 24C04BN XBLW |+| Package | SOP-8 |+| Category | Memory |+| Pins | 8 |++## Ordering variants++- `24C04BNBN`+- `24C04BNN`+- `24C04BNMN`+- `24C04BNTN`+- `24C04BNDN`+- `24C04BND6`+- `24C04BNS`++## CAD (KiCad official)++- Symbol: `24C04BN`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [XBLW 24C04BN XBLW datasheet](docs/24c04bn-datasheet.pdf) (20 pp, sha256 `aed51281433cee82`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
