DESCRIPTION
The MB90370 series is a line of general-purpose, 16-bit microcontrollers designed for those applications which require high-speed real-time processing. The instruction set is designed to be optimized for controller applications which inheriting the AT architecture of F2MC-16LX series and allow a wide range of control tasks to be processed efficiently at high speed.

FEATURES
● Clock
    • Embedded PLL clock multiplication circuit
    • Operating clock (PLL clock) can selected from divided-by-2 of oscillation or one to four times the oscillation (at oscillation of 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 3.3 V)
● CPU addressing space of 16 Mbytes
    • Internal 24-bit addressing
