AT24CM02-SSHM-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); internally pulled down to GND if left floating, and connecting it to a known state is recommended. |
| 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 clocks data in on the rising edge and out on the falling edge; must be forced high when the bus is idle or pulled high with an external pull-up resistor. |
| 7 | WP | input | Write-protect input: connected to GND allows normal writes, connected directly to VCC inhibits all writes to the full array; internally pulled down to GND if left floating. |
| 8 | VCC | power_in | Device power supply pin, operating from 1.7V to 5.5V for this -M voltage option; operation at invalid VCC voltages should not be attempted. |
