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.
