■ DESCRIPTION

MB90455 series devices are general-purpose high-performance 16-bit micro controllers designed for process

control of consumer products, which require high-speed real-time processing.

The system, inheriting the architecture of F²MC* family, employs additional instruction ready for high-level lan-

guages, expanded addressing mode, enhanced multiply-divide instructions, and enriched bit-processing instruc-

tions. Furthermore, employment of 32-bit accumulator achieves processing of long-word data (32 bits).

The peripheral resources of MB90455 series include the following:

8/10-bit A/D converter, UART 1, 8/16-bit PPG timer, 16-bit input-output timer (16-bit free-run timer, input capture

0, 1, 2, 3 (ICU)).

■ 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 4 times of oscillation clock (for 4-MHz oscillation clock, 4 MHz to 16 MHz).

• Operation by sub-clock (8.192 kHz) is allowed.

• Minimum execution time of instruction: 62.5 ns (when operating with 4-MHz oscillation clock, and 4-time multi-

plied PLL clock).
