FUJITSU MICROELECTRONICS DS07-13809-1E DATA SHEET 16-bit Proprietary Microcontroller CMOS 2 F MC-16FX MB96390 Series *1 MB96F395 DESCRIPTION MB96390 series is based on Fujitsus 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. *1: These devices are under development and specification is preliminary. These products under development may change its specification without notice. 2 Note: F MC is the abbreviation of Fujitsu Flexible Microcontroller For the information for microcontroller supports, see the following web site. This web site includes theCustomer Design Review Supplemen which provides the latest cautions on system development and the minimal requirements to be checked to prevent problems before the system development.
