DESCRIPTION
MB96640 series is based on FUJITSU’s advanced F
2
MC-16FX architecture (16-bit with instruction
pipeline for RISC-like performance). The CPU uses the same instruction set as the established F
2
MC-16LX
family thus allowing for easy migration of F
2
MC-16LX Software to the new F
2
MC-16FX products.
F
2
MC-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.
Note: F

MC is the abbreviation of FUJITSU Flexible Microcontroller.
