HG24C08MM from HGSEMI, in a MSOP-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/page address input. On the HG24C08 this pin is a No Connect (not used for hardware addressing) and should be tied to GND. Input capacitance 6 pF max. |
| 2 | A1 | input | Device/page address input. On the HG24C08 this pin is a No Connect (not used for hardware addressing) and should be tied to GND. Input capacitance 6 pF max. |
| 3 | A2 | input | Device address input. Compared against bit A2 of the incoming I²C device-address byte to enable this chip; up to two HG24C08 devices can share a single bus. VIH = 0.7·VCC min, VIL = 0.3·VCC max. Input capacitance 6 pF max. |
| 4 | GND | power_in | Ground reference for supply and logic. |
| 5 | SDA | bidirectional | I²C serial data, bidirectional, open-drain. Requires an external pull-up resistor (typ. 1.3 kΩ at 2.5 V/5 V, 10 kΩ at 1.8 V). Input capacitance 8 pF max. Sinks IOL = 3.0 mA at VOL ≤ 0.4 V (VCC = 5 V). |
| 6 | SCL | input | I²C serial clock input. Positive edge clocks data into the EEPROM; negative edge clocks data out. Schmitt-triggered, filtered input. Max fSCL = 1 MHz at 5 V, 400 kHz at 1.7 V-2.7 V. Input capacitance 6 pF max. |
| 7 | WP | input | Write Protect. Tie to GND for normal read/write operations. When tied to VCC, the entire 8K array is write-protected in hardware. Should not be left floating. |
| 8 | VCC | power_in | Supply voltage, 1.7 V to 5.5 V. Read current ≈ 0.4 mA typ (1 mA max) at 5 V/100 kHz; write current ≈ 2 mA typ (3 mA max); standby current ≤ 2 µA. Decouple with a local bypass capacitor to GND. |
