AT24C08N from HGSEMI, in a DIP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | No connect. Not internally bonded; leave floating or optionally tie to Vss. |
| 2 | NC | unconnected | No connect. Not internally bonded; leave floating or optionally tie to Vss. |
| 3 | E2 | input | Slave address select input for AT24C08 (bit E2 of the I2C device address, allowing up to 2 devices on one bus). Internally pulled down to Vss if left floating, forcing the corresponding address bit to 0. Logic levels: VIL <= 0.3VCC, VIH >= 0.7VCC. |
| 4 | Vss | power_in | Ground reference for VCC supply. |
| 5 | SDA | bidirectional | I2C serial data input/output. Open-drain; requires an external pull-up resistor to VCC (typical 1.3 kOhm at 2.5-5.5 V, 10 kOhm at 1.7 V). Wire-OR compatible with other open-drain devices; VOL <= 0.4 V at IOL = 2.1 mA (VCC = 3.0 V). |
| 6 | SCL | input | I2C serial clock input. Data clocked in on positive edge and out on negative edge. Supports up to 400 kHz (Fast Mode) or 1 MHz (Fast Mode Plus) across 1.7-5.5 V. Schmitt-triggered with noise-suppression filter (tI = 100 ns at 400 kHz). |
| 7 | WCB | input | Write control (active-low enable). Tie to Vss (or leave floating - internally pulled down to Vss) to allow normal write operations; tie to VCC to inhibit all write operations to the memory array. Provides hardware write protection. |
| 8 | VCC | power_in | Supply voltage input, 1.7 V to 5.5 V. Typical standby current 0.5-1.0 uA; read current 0.2 mA and write current 0.8 mA typical at 400 kHz. Absolute maximum 6.5 V. |
