**onsemi** · EEPROM · SOIC-8

CAT25010VI-GT3 from onsemi, 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 | CS | input | Active-low chip select input that enables the device; when high, SO is tri-stated and the device is in Standby Mode, and each session needs a high-to-low then low-to-high transition. |
| 2 | SO | tri_state | Serial data output that shifts data out on the falling edge of SCK in SPI modes (0,0) and (1,1), and is high impedance when CS is high or during hold. |
| 3 | WP | input | Write protect input that allows all write operations when held high and inhibits all write operations when tied low. |
| 4 | VSS | power_in | Ground. |
| 5 | SI | input | Serial data input that accepts op-codes, addresses and data, latched on the rising edge of SCK in SPI modes (0,0) and (1,1). |
| 6 | SCK | input | Serial clock input from the host used to synchronize communication, up to 20 MHz at 5 V. |
| 7 | HOLD | input | Active-low hold input that pauses serial communication when taken low (with SCK low) and resumes when taken high; tie to VCC when unused. |
| 8 | VCC | power_in | Power supply, 1.8 V to 5.5 V supply voltage range. |
