MC-16FX MB96380 Series
MB96380 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 enabling thus easy migration
of 16LX Software to the new 16FX products. In comparison with the previous generation, the 16FX products
include significantly improved performance even at the same operation frequency, a reduced power consumption
and a faster start-up time.
For highest processing speed at optimized power consumption an internal PLL can be selected to supply the
CPU with up to 56MHz operation frequency from an external 4MHz resonator. The result is a minimum instruction
cycle time of 17.8ns going together with excellent EMI behavior. An on-chip clock modulation circuit significantly
reduces emission peaks in the frequency spectrum. The emitted power is minimized by the on-chip voltage
regulator that reduces the internal CPU voltage. A flexible clock tree allows to select suitable operation frequencies
for peripheral resources independent of the CPU speed.
