MB90T678 - 16-bit Proprietary Microcontroller

The MB90670/675 series is a member of 16-bit proprietary single-chip microcontroller F2MC

1-16L family designed to be combined with an ASIC (Application Specific IC) core.

• Clock Embedded PLL clock multiplication circuit Operating clock (PLL clock) can be selected from divided-by-2 of oscillation or one to four times the oscillation (at oscillation of 4 MHz, 4 MHz to 16 MHz). Minimum instruction execution time of 62.5 ns (at oscillation of 4 MHz, four times the PLL clock, operation at Vcc of 5.0 V).
• CPU addressing space of 16 Mbytes Internal addressing of 24-bit External accessing can be performed by selecting 8/16-bit bus width (external bus mod.
