34LC02-I
Microchip Tech · EEPROM · SOIC-8
34LC02-I from Microchip Tech, in a SOIC-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 | Chip address input whose level is compared with the corresponding slave address bit, and it must be connected to either VSS or VCC; the A0 pin is also used to detect VHV for the software write-protect commands. |
| 2 | A1 | input | Chip address input whose level is compared with the corresponding slave address bit, and it must be connected to either VSS or VCC. |
| 3 | A2 | input | Chip address input whose level is compared with the corresponding slave address bit, and it must be connected to either VSS or VCC. |
| 4 | VSS | power_in | Ground reference for the device. |
| 5 | SDA | bidirectional | Open-drain serial address/data I/O that requires a pull-up resistor to VCC (typically 10 kΩ for 100 kHz, 2 kΩ for 400 kHz), and SDA may change only while SCL is low for normal data transfer. |
| 6 | SCL | input | Serial clock input used to synchronize data transfer to and from the device. |
| 7 | WP | input | Hardware write-protect input: tied to VCC enables hardware write protection of the array, and tied to VSS disables it. |
| 8 | VCC | power_in | Power supply, specified in the pin table as +1.7V to 5.5V. |
