The MB90495G Series is a 16-bit high-performance microcontroller produced by Fujitsu. The series supports high-temperature environments and can reach a maximum of +125 °C. Its characteristics include a built-in PLL clock multiplier circuit, support for 1/2 oscillator clock or 1~4 times oscillator clock (for a 4MHz oscillator clock, support 4~16MHz) machine clock (PLL) clock, subclock behavior selection (8.192 kHz) and minimum instruction execution time (40 ns).
