This chapter explains the features and basic specifications of the Monolith (MB90M405).
The MB90M405 Series is a general-purpose 16-bit microcontroller developed for applications requiring
fluorescent lamp panel control and contains 60 high-voltage withstand output pins required for a fluorescent
lamp.
As with the original F
2
MC-8L and F
2
MC-16L families, the instruction system inherits the AT architecture, and
has extended high-level language interface instructions and the extended addressing modes, enhanced
multiplication/division instructions (signed), and enhanced bit processing. In addition, a 32-bit accumulator
enables handle long word processing.
1.1 Features
•
Clock:
•
PLL Clock multiplication circuit built-in
•
Operating clock (PLL clock) generated by dividing original oscillation by 2 or by multiplying original
oscillation by 1 to 4 (2.1 MHz to 16.8 MHz at original oscillation of 4.2 MHz). Can be selected.
•
Minimum instruction execution time is 59.5 ns (when the original oscillation is 4.2 MHz, the PLL clock is
generated by multiplying the original oscillation by 4, and Vcc = 3 V).
•
It is possible to generate an external output as a clock output by dividing the original oscillation by 16, 32,
64, or 128.
•
Maximum memory space: 16 Mbytes
•
24-bit addressing in memory space
•
Instruction system suited for controller
•
Applicable data types (bit, byte, word, long-word)
•
Various addressing modes: 23 types
•
High code efficiency
•
High-precision operation with 32-bit accumulator
•
Signed multiplication and division instructions and enhanced
RETI
instruction
•
Powerful instruction system applicable to high-level language (C) or multitasking
•
System stack pointer
•
Symmetric instruction set and barrel shift instruction
•
Program patch function (2-address pointer)
•
Shortened execution time: 4-byte instruction queue
•
Powerful interrupt function (eight programmable priority levels)
•
Powerful interrupt function for 32 interrupt factors
•
Data transfer function (extended intelligent I/O service function: 16 channels maximum)
•
Low-power consumption (standby mode)
•
Sleep mode (stops CPU operating clock)
•
Pseudo-timer mode (stops everything except original oscillation and time-base timer)
•
Stop mode (stops original oscillation)
•
CPU Intermittent operation mode
•
