# XT25F02ESOIGU

**XTX** · NOR FLASH · SO-8

XT25F02ESOIGU from XTX, in a SO-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 | Chip Select input for the serial flash, as described in the Pin Description table. |
| 2 | SO (IO1) | bidirectional | Data Output (Data Input Output 1) in standard SPI and an I/O line in Dual SPI mode. |
| 3 | NC | unconnected | No internal connection on the SO8 150mil package. |
| 4 | VSS | power_in | Ground reference for the device. |
| 5 | SI (IO0) | bidirectional | Data Input (Data Input Output 0) in standard SPI and an I/O line in Dual SPI mode. |
| 6 | SCLK | input | Serial Clock Input for the serial interface. |
| 7 | NC | unconnected | No internal connection on the SO8 150mil package. |
| 8 | VCC | power_in | Power supply input, single supply range 2.7~3.6V per the datasheet features. |
