AT24CM01-XHD-B from Microchip Tech, in a TSSOP-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 in the datasheet. |
| 2 | A1 | input | Device address input that can be hardwired or left floating; floating pin is internally pulled down to GND if coupling to the VCC plane is <3pF, otherwise connect to GND, allowing up to four devices on one bus. |
| 3 | A2 | input | Device address input that can be hardwired or left floating; floating pin is internally pulled down to GND if coupling to the VCC plane is <3pF, otherwise connect to GND, allowing up to four devices on one bus. |
| 4 | GND | power_in | Ground. |
| 5 | SDA | bidirectional | Bidirectional serial data pin, open drain driven and may be wire-ORed with other open drain or open collector devices. |
| 6 | SCL | input | Serial clock input that positive edge clocks data into the EEPROM and negative edge clocks data out. |
| 7 | WP | input | Write protect input: connected to GND allows normal write operations, connected to VCC inhibits all writes to the memory (full array), and a floating pin is internally pulled down to GND if coupling to the VCC plane is <3pF. |
| 8 | VCC | power_in | Power supply, 2.5V to 5.5V for the 2.5V (D) option. |
