I was a bit surprised about the use of a FPGA directly connected to a 5V bus, but Infinion/Cypress describes their CY8C58LP as 'programmable system on a chip' (ARM M3 core, the usual set of interface subsystems and a few 'universal digital blocks' (like a mini FPGA). And yes, it is 5V tolerant. Looks interesting. https://www.infineon.com/dgdl/Infineon-PSoC_5LP_CY8C58LP_Family_Datasheet_Programmable_System-on-Chip_(PSoC_)-DataSheet-v15_00-EN.pdf?fileId=8ac78c8c7d0d8da4017d0ec547013ab9 https://www.infineon.com/dgdl/Infineon-PSoC_5LP_CY8C58LP_Fam...
