Microchip Tech · EEPROM · TSSOP-8
AT24C08C-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 | No Connect pin on the TSSOP-8 package, with no internal connection stated by the datasheet. |
| 2 | NC | unconnected | On the AT24C08C this pin is a no connect; it is the A1 device address input only on the AT24C04C. |
| 3 | A2 | input | Device address input that is hard-wired to GND or VCC and is internally pulled down to GND if not driven; Microchip recommends a pull-up of 10 kΩ or less when one is used. |
| 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. |
| 6 | SCL | input | Serial clock input where SDA data is latched on the rising edge and output data is clocked out on the falling edge, and which must be forced high when the bus is idle or pulled high externally. |
| 7 | WP | input | Write-protect input where connecting it to GND allows normal writes and connecting it to VCC inhibits all writes to the protected memory (full array); it is internally pulled down to GND if left floating. |
| 8 | VCC | power_in | Device power supply pin; operation at invalid VCC voltages may produce spurious results and should not be attempted. |
