AT24CM01-SHD-T from Microchip Tech, in a SOIC-8-208mil. 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, listed in the pin table as not connected to the device function. |
| 2 | A1 | input | Device address input that can be hardwired or left floating; floating pins are internally pulled down to GND when coupling to the board VCC plane is <3pF, and Atmel recommends connecting them to GND if coupling is >3pF. |
| 3 | A2 | input | Device address input that can be hardwired or left floating; floating pins are internally pulled down to GND when coupling to the board VCC plane is <3pF, and Atmel recommends connecting them to GND if coupling is >3pF. |
| 4 | GND | power_in | Ground reference for the device. |
| 5 | SDA | bidirectional | Bidirectional serial data pin that is open-drain driven and may be wire-ORed with other open-drain or open-collector devices. |
| 6 | SCL | input | Serial clock input: data is positive-edge clocked into the device and negative-edge clocked out of the device. |
| 7 | WP | input | Write protect input: connecting it to GND allows normal write operations, while connecting it to VCC inhibits all write operations to the memory. |
| 8 | VCC | power_in | Power supply; the 1.7V option operates from 1.7V to 5.5V and the 2.5V option from 2.5V to 5.5V (D-suffix part). |
