FM25040B-GTR from Infineon Cypress Semicon, 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 activates the device; device enters standby mode and ignores other inputs when CS is HIGH. |
| 2 | SO | tri_state | Serial output driven on the falling edge of SCK during read operations; remains tri-stated at all other times including when HOLD is LOW. |
| 3 | WP | input | Active LOW write protect input that prevents all write operations including Status Register modification when LOW; must be tied to VDD if not used. |
| 4 | VSS | power_in | Power supply ground reference; must be connected to the system ground. |
| 5 | SI | input | Serial input pin sampled on the rising edge of SCK; must always be driven to a valid logic level to meet IDD specifications. |
| 6 | SCK | input | Serial clock input that synchronizes all I/O activity; operating frequency may be 0 to 20 MHz and may be interrupted at any time. |
| 7 | HOLD | input | HOLD input used to interrupt memory operations without aborting them; when LOW with SCK LOW, operation is suspended; must be tied to VDD if not used. |
| 8 | VDD | power_in | Power supply input with operating voltage range of 4.5 V to 5.5 V; provides power for all internal device circuits. |
