■ DESCRIPTION
MB90925 series is a 16-bit general-purpose high-capacity microcontroller designed for vehicle meter control
applications etc.
The instruction set retains the same AT architecture as F2MC-8L and F2MC-16L series, with further refinements
including high-level language instructions, expanded addressing mode, enhanced signed multiplication and
division computation and bit processing.
In addition, a 32-bit accumulator is built in to enable long word processing.
Note : F2MC is the abbreviation of FUJITSU Flexible Microcontroller.
■ FEATURES
• Clock
Built-in PLL clock frequency multiplication circuit.
Selection of machine clocks (PLL clocks) is allowed among frequency division by 2 on oscillation clock and
multiplication of 1 to 4 times of oscillation clock(for 4 MHz oscillation clock, 4 MHz to 16 MHz).
Operation by sub clock(up to 50 kHz : 100 kHz oscillation clock divided by 2).
