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. Tied high or low to set the least significant bit of the 3-bit hardware slave address (I2C address = 1010_A2A1A0). Allows up to 8 HX24C02 devices to share one I2C bus. |+| 2 | A1 | input | Device address input bit 1. Tied high or low to set the middle bit of the 3-bit hardware slave address (I2C address = 1010_A2A1A0). |+| 3 | A2 | input | Device address input bit 2. Tied high or low to set the most significant bit of the 3-bit hardware slave address (I2C address = 1010_A2A1A0). |+| 4 | GND | power_in | Ground / negative supply return. Reference for all voltages. |+| 5 | SDA | bidirectional | I2C serial data line. Open-drain bidirectional data pin; requires an external pull-up resistor (typ. 10 kΩ) to VCC. Data on SDA may only change while SCL is low. |+| 6 | SCL | input | I2C serial clock input. Driven by the bus master; requires an external pull-up resistor (typ. 10 kΩ) to VCC. Max frequency 1 MHz at VCC=5V (400 kHz at 1.8V). |+| 7 | WP | input | Write protect input. When tied high (VCC), write operations to the entire memory array are inhibited (hardware write protection); when tied low (GND), normal read/write operations are allowed. |+| 8 | VCC | power_in | Positive supply voltage. Operating range 1.8V to 5.5V; absolute maximum 5.5V. Bypass with a 1 µF ceramic capacitor close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HX hengjiaxing |+| Package | SOP-8 |+| Category | Memory |+| Pins | 8 |++## Ordering variants++- `HX24C02PP`+- `HX24C02PD`+- `HX24C02PS`++## CAD (KiCad official)++- Symbol: `HX24C02P`+- 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:** [HX hengjiaxing datasheet](docs/hx24c02p-datasheet.pdf) (None pp, sha256 `cc8112afa8214613`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
