16-bit Proprietary Microcontroller
F2MC-16LX MB90460/465 Series
The MB90460/465 series is a line of general-purpose, Fujitsu 16-bit microcontrollers designed for process control
applications which require high-speed real-time processing, such as consumer products.
While inheriting the AT architecture of the F2MC* family, the instruction set for the F2MC-16LX CPU core of the
MB90460/465 series incorporates additional instructions for high-level languages, supports extended addressing
modes, and contains enhanced multiplication and division instructions as well as a substantial collection of
improved bit manipulation instructions. In addition, the MB90460/465 has an on-chip 32-bit accumulator which
enables processing of long-word data.
The peripheral resources integrated in the MB90460/465 series include : an 8/10-bit A/D converter, UARTs (SCI)
0 to 1, 16-bit PPG timer, a multi-functional timer (16-bit free-run timer, input capture units (ICUs) 0 to 3, output
compare units (OCUs) 0 to 5, 16-bit PPG timer, a waveform generator) , a multi-pulse generator (16-bit PPG
timer, 16-bit reload timer, waveform sequencer) , PWC 0 to 1, 16-bit reload timer and DTP/external interrupt.
