■ DESCRIPTION

The MB90370/375 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 be 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 16M bytes
• Internal 24-bit addressing
• Instruction set optimized for controller applications
