HX24C02P from HX hengjiaxing, in a SOP-8. 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. |
