■ DESCRIPTION
The MB90920 series is a family of general-purpose FUJITSU SEMICONDUCTOR 16-bit microcontrollers de-
signed for applications such as vehicle instrument panel control.
The instruction set retains the AT architecture from the F2MC-8L and F2MC-16LX families, with further refinements
including high-level language instructions, extended addressing modes, improved multiplication and division
operations (signed), and bit processing. In addition, long word processing is made possible by the inclusion of a
built-in 32-bit accumulator.
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 two on oscillation clock, and
multiplication of 1 to 8 times of oscillation clock (for 4 MHz oscillation clock, 4 MHz to 32 MHz).
Operation by sub clock (up to 50 kHz : 100 kHz oscillation clock divided by two) is allowed.
16-bit input capture (8 channels)
Detects rising, falling, or both edges.
16-bit capture register
× 8
The value of a 16-bit free-run timer counter is latched upon detection of an edge input to pin and an interrupt
request is generated.
