Chapter 1:
Overview
The MB90580 series 16-bit microcontrollers are designed for applications that require high-speed
real-time processing. These microcontrollers feature functions that are suitable for controlling car audio
and electronic appliances.

1.1 Features

• Clock
Embedded PLL Clock Multiplication Circuit
Operating clock (PLL clock) can e 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 83.3ns (at oscillation of 4 MHz, three 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 mode)
• Instruction set optimized for controller applications
Rich data types (bit, byte, word, long word)
Rich addressing mode (23 types)
High code efficiency
Enhanced precision calculation realized by the 32-bit accumulatorInstruction set designed for high level
language (C) and multi-task operations
Adoption of system stack pointer
Enhanced pointer indirect instructions
Barrel shift instructions

Extended intelligent I/O service function (EI
• Low-power consumption (stand-by) mode
Sleep mode (mode in which CPU operating clock is stopped)
Timebase timer mode (mode in which other than oscillation and timebase timer are stopped)
Stop mode (mode in which oscillation is stopped)
CPU intermittent operation mode
Hardware stand-by mode
• I/O port
Maximum of 77 ports
