AT24CM01-XHM-T 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 | Not connected; the datasheet assigns this pin no electrical function. |
| 2 | A1 | input | Device address input hardwired to GND or VCC for multi-device addressing; it is internally pulled down to GND if left floating, and Microchip recommends driving it to a known state, using a pull-up of 10 kΩ or less. |
| 3 | A2 | input | Device address input hardwired to GND or VCC for multi-device addressing; it is internally pulled down to GND if left floating, and Microchip recommends driving it to a known state, using a pull-up of 10 kΩ or less. |
| 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 with an external pull-up resistor not exceeding 10 kΩ, and may be wire-ORed with other open-drain devices on the bus. |
| 6 | SCL | input | Serial clock input: command and input data on SDA are latched on the rising edge of SCL, output data is clocked out on the falling edge, and SCL must be forced high when the bus is idle or pulled high by an external resistor. |
| 7 | WP | input | Write-protect input: connecting it to GND allows normal write operations, while connecting it to VCC inhibits all writes to the protected memory (full array); if left floating it is internally pulled down to GND, and a pull-up of 10 kΩ or less is recommended. |
| 8 | VCC | power_in | Device power supply pin; the device operates from 1.7 V to 5.5 V, and operation at invalid VCC voltages may produce spurious results and should not be attempted. |
