H24C02S

HXY MOSFET · EEPROM · SOT-23-5L

H24C02S from HXY MOSFET, in a SOT-23-5L. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 SCL input Serial clock input; the rising edge latches data into the EEPROM and the falling edge clocks data out.
2 GND power_in Ground.
3 SDA bidirectional Serial data input / open-drain output; bi-directional line that can be wired-OR with other open-drain devices and is typically pulled high by an external resistor.
4 VCC power_in Power supply, 1.8V to 5.5V, with a decoupling capacitor of at least 10nF recommended.
5 WP input Write protect input; programming is disabled when connected to VIH or VCC and allowed when left unconnected or at VIL, with read operations unaffected.
