AT24C64D-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 | A0 | input | Device address input hard-wired to GND or VCC, internally pulled to GND if left floating, and Atmel recommends connecting it to a known state with a pull-up of 10k or less. |
| 2 | A1 | input | Device address input hard-wired to GND or VCC, internally pulled to GND if left floating, and Atmel recommends connecting it to a known state with a pull-up of 10k or less. |
| 3 | A2 | input | Device address input hard-wired to GND or VCC, internally pulled to GND if left floating, and Atmel recommends connecting it to a known state with a pull-up of 10k or less. |
| 4 | GND | power_in | Ground reference for the device; the voltage on any pin is rated from -1.0 V to +7.0 V with respect to ground. |
| 5 | SDA | bidirectional | Open-drain bidirectional serial data pin that may be wire-ORed with other open-drain or open-collector devices and requires an external pull-up because SDA is normally pulled high. |
| 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: connected to GND allows normal write operations, connected to VCC inhibits all writes to the memory, and Atmel recommends a known state with a pull-up of 10k or less. |
| 8 | VCC | power_in | Device power supply, specified for 1.7 V to 5.5 V operation. |
