Thank you for contacting Cypress Community.
We do not have any particular schematic for interfacing 25FL512S with LPC 1768.
You can connect all the SPI signals (SI, SO, SCK, VCC, GND, CS#) directly to the controller.
I'm attaching an LLD zipped folder. You can use it as a reference code.
Thanks and Regards,
