MC-16FX MB96370 Series
MB96375RS/RW, MB96F378HS/HW, MB96F379RS/RW
■
DESCRIPTION
MB96370 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 highest processing speed at optimized power consumption an internal PLL can be selected to supply
the CPU with up to 40MHz operation frequency from an external 4MHz resonator. The result is a minimum
instruction cycle time of 25ns 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.
