# AT24C08C-XHM-T-TUDI

**Tudi** · EEPROM · TSSOP-8

AT24C08C-XHM-T-TUDI from Tudi, 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 that is hardwired; on the 8K AT24C08 the A0 pin is no connect because the bits are used for memory page addressing. |
| 2 | A1 | input | Device address input that is hardwired; on the 8K AT24C08 the A1 pin is no connect because the bits are used for memory page addressing. |
| 3 | A2 | input | Device address input that is hardwired and must compare to the A2 bit of the device address word on the 8K device. |
| 4 | GND | power_in | Ground. |
| 5 | SDA | bidirectional | Bidirectional serial data pin, open-drain driven, 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 read/write operations, connected to VCC enables write protection of the full array. |
| 8 | VCC | power_in | Power supply, 1.7V to 5.5V operating range. |
