HG24C08CM

HGSEMI · EEPROM · SOP-8

HG24C08CM from HGSEMI, in a SOP-8. 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 NC unconnected No connect pin; the datasheet pin-out drawing shows it as NC and gives no function.
2 NC unconnected No connect pin; the datasheet pin-out drawing shows it as NC and gives no function.
3 E2 input Device address input that can be tied to VCC or GND in any combination, allowing up to eight devices on one bus; if left floating it is internally pulled down to GND.
4 GND power_in Ground reference for the power supply, to be connected to system ground.
5 SDA bidirectional Serial data pin, an open-drain bidirectional input/output used to transfer data to and from the device.
6 SCL input Serial clock input that controls data flow; input data is latched on the rising edge of SCL and output data is clocked out on the falling edge.
7 WP input Write-protect input: tied to VCC it makes the whole memory array read-only, tied to GND it enables writes, and if left floating it is internally pulled down to GND.
8 VCC power_in Device power supply, 1.7V to 5.5V; operation at invalid VCC voltages may produce spurious results.
