HG24C08CMM

HGSEMI · EEPROM · MSOP-8

HG24C08CMM 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 NC unconnected No internal connection. May be left floating or tied to GND.
2 NC unconnected No internal connection. May be left floating or tied to GND.
3 E2 input Device address input. Hard-wired to VCC or GND to set the E2 address bit for bus multi-drop (up to 8 devices with two device-type identifiers). Internally pulled down to GND when left floating.
4 GND power_in Ground reference for the power supply. Connect to system ground.
5 SDA bidirectional Serial data. Open-drain bidirectional I/O for the 2-wire I2C interface; requires an external pull-up to VCC. Data is transferred MSB-first, latched on rising SCL and driven on falling SCL.
6 SCL input Serial clock input for the 2-wire I2C interface. Supports up to 400 kHz standard and 1 MHz high-speed transfer rates; requires an external pull-up to VCC.
7 WP input Hardware write-protect input. Tie to VCC to make the whole memory array read-only; tie to GND to enable writes. Internally pulled down to GND when left floating. When driven high, only the device address and word address bytes are ACKed; data bytes are NACKed.
8 VCC power_in Device power supply, 1.7 V to 5.5 V. Operation outside this range may produce spurious results and must be avoided.
