25C080 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 | CS | input | Chip Select input: a low level selects the device, a high level deselects it, forces Standby mode and puts SO in high-impedance. |
| 2 | SO | tri_state | Serial Data Output: data is shifted out on this pin after the falling edge of the serial clock, and it is high-impedance when the device is deselected. |
| 3 | WP | input | Write-Protect pin: when low and WPEN bit is high, writes to the nonvolatile Status register bits are disabled; the pin function is blocked when WPEN is low. |
| 4 | VSS | power_in | Ground. |
| 5 | SI | input | Serial Data Input: receives instructions, addresses and data, latched on the rising edge of the serial clock. |
| 6 | SCK | input | Serial Clock input: synchronizes communication, with SI latched on the rising edge and SO updated after the falling edge. |
| 7 | HOLD | input | Hold input: pulled low to pause serial communication without resetting the sequence while the device stays selected, and must be held high when not in use. |
| 8 | VCC | power_in | Supply voltage: 4.5V to 5.5V for the 25C080, with absolute maximum of 7.0V. |
