AT24CM02-SSHD-B from Microchip Tech, in a SOIC-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 with no internal function stated. |
| 2 | NC | unconnected | No connect pin with no internal function stated. |
| 3 | A2 | input | Device address input, hard-wired to GND or VCC (up to two devices per bus); if not driven it is internally pulled down to GND, and connecting it to a known state is recommended (pull-up 10 kΩ or less). |
| 4 | GND | power_in | Ground reference for the power supply, to be connected to system ground. |
| 5 | SDA | bidirectional | Open-drain bidirectional serial data pin that requires an external pull-up resistor not exceeding 10 kΩ and may be wire-ORed with other open-drain devices. |
| 6 | SCL | input | Serial clock input that controls data flow; input data is latched on the rising edge and output data is clocked out on the falling edge, and it must be forced high or pulled up when the bus is idle. |
| 7 | WP | input | Write-protect input: connected to GND allows normal writes, connected to VCC inhibits all writes to the full array; internally pulled down to GND if not driven. |
| 8 | VCC | power_in | Device power supply pin; the AT24CM02-SSHD variant operates from 2.5V to 5.5V. |
