s 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)).

s 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).
