16-bit Proprietary Microcontroller
F2MC-16LX MB90860A Series
MB90F867A (S) , MB90867A (S)
The MB90860A-series is Fujitsu 16-bit general-purpose microcontroller which enhances each kind of timers and
communication macros. With the new 0.35 µm CMOS technology, Fujitsu now offers 128 Kbytes on-chip FLASH-
ROM program memory. An internal voltage booster removes the necessity for a second programming voltage.
The power supply (3 V) is supplied to the internal MCU core from an internal regulator circuit. This creates a
major advantage in terms of EMI and power consumption.
The internal PLL clock frequency multiplier provides an internal 42 ns instruction cycle time from an external
4 MHz clock.
The unit features an 8 channel Output Compare Unit and 8 channel Input Capture Unit with 2 separate 16-bit free
running timers. 4 UARTs constitute additional functionality for communication purposes.
