MB96F683/F685*
DESCRIPTION
MB96680 series is based on Fujitsu’s advanced 16FX architecture (16-bit with instruction pipeline for
RISC-like performance). The CPU uses the same instruction set as the established 16LX series - thus
allowing for easy migration of 16LX Software to the new 16FX products.
16FX 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 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.
*: These devices are under development and specification is preliminary.
These products under development may change its specification without notice.
