# AT24CM02-SSHM-T

**Microchip Tech** · EEPROM · SOIC-8

AT24CM02-SSHM-T 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; the datasheet lists it as no connection in the 8-Lead SOIC pin function table. |
| 2 | NC | unconnected | No Connect pin; the datasheet lists it as no connection in the 8-Lead SOIC pin function table. |
| 3 | A2 | input | Device address input hard-wired to GND or VCC; if left floating it is internally pulled down to GND, and Microchip recommends using a pull-up of 10 kΩ or less when a pull-up is used. |
| 4 | GND | power_in | Ground reference for the power supply, which should be connected to the system ground. |
| 5 | SDA | bidirectional | Open-drain bidirectional serial data pin that must be pulled high using an external pull-up resistor not exceeding 10 kΩ. |
| 6 | SCL | input | Serial clock input; SDA data is latched on the rising edge of SCL and output data is clocked out on the falling edge, and SCL must be forced high or pulled high when the bus is idle. |
| 7 | WP | input | Write-protect input: connected to GND allows normal write operations, connected to VCC inhibits writes to the full array, and if floating it is internally pulled down to GND (pull-up of 10 kΩ or less recommended). |
| 8 | VCC | power_in | Device power supply pin; operation at invalid VCC voltages may produce spurious results and should not be attempted. |
