CY96690 series is based on Cypress advanced F2MC-16FX architecture (16-bit with instruction pipeline for RISC-like performance). The CPU uses the same instruction set as the established F2MC-16LX family thus allowing for easy migration of F 2MC-16LX Software to the new F2MC-16FX products. F2MC-16FX product improvements compared to the previous generation include significantly improved performance - even at the same operation frequency, reduced power consumption and faster start-up time. For high processing speed at optimized power consumption an internal PLL can be selected to supply the CPU with up to 32MHz operation frequency from an external 4MHz to 8MHz resonator. The result is a minimum instruction cycle time of 31.2ns going together with excellent EMI behavior. The emitted power is minimized by the on-chip voltage regulator that reduces the internal CPU voltage. A flexible clock tree allows selecting suitable operation frequencies for peripheral resources independent of the CPU speed.​
