■ DESCRIPTION
The MB90800 series is a general-purpose 16-bit microcontroller that has been developed for high-speed realtime processing required for industrial and office automation equipment and process control, etc. The LCD controller of 48 segment four common is built into.
Instruction set has taken over the same AT architecture as in the F2MC-8L and F2MC-16L, and is further enhanced to support high level languages, extend addressing mode, enhanced divide/multiply instructions with sign and enrichment of bit processing. In addition, long word processing is now available by introducing a 32-bit accumulator.

■ FEATURES
• Clock
    • Built-in PLL clock frequency multiplication circuit
    • Operating clock (PLL clock) : divided-by-2 of oscillation (at oscillation of 6.25 MHz) or 1 to 4 times the oscillation (at oscillation of 6.25 MHz to 25 MHz).
    • Minimum instruction execution time of 40.0 ns (at oscillation of 6.25 MHz, four times the PLL clock, operation at Vcc = 3.3 V)
• The maximum memory space:16 Mbytes
    • 24-bit internal addressing
    • Bank addressing

    • Wide choice of addressing modes (23 types)
    • High code efficiency
    • Enhanced high-precision computing with 32-bit accumulator
    • Enhanced Multiply/Divide instructions with sign and the RETI instruction

    • Sleep mode (a mode that halts CPU operating clock)
    • Time-base timer mode (a mode that operates oscillation clock and time-base timer)
    • Watch mode (mode in which only the subclock and watch timers operate)
    • Stop mode (a mode that stops oscillation clock and sub clock)
    • CPU blocking mode (operating CPU at each set cycle)
• Package
