HG24C08M5

HGSEMI · EEPROM · SOT-23-5

HG24C08M5 from HGSEMI, in a SOT-23-5. 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 that clocks data into the EEPROM on the positive edge and out of it on the negative edge.
2 GND power_in Ground.
3 SDA bidirectional Bidirectional open-drain serial data pin that may be wire-ORed with other open-drain or open-collector devices and is normally pulled high externally.
4 VCC power_in Power supply, 1.7V to 5.5V operating range.
5 WP input Write protect input: connected to GND allows normal read/write, connected to VCC write-protects the full 8K array.
