Preface

Objective of Manual and Target Audience

The MB90M405 Series is a general-purpose semiconductor device in the F2MC-16LX family. It is a 16-bit

single-chip microcontroller ASIC (Application Specific IC). This manual explains the functionsand

operationsof the MB90M405 Series for engineers who design products using this device.

How to Read This Manual

Page Organization

A summary is given below the title of each section. A title of the main section is noted in the sub-section to

recognize a current-reading section.

Index Organization

(1) Register map index

The register map index formatis similar to the I/O map and it allows search for the page explaining the

bits of each register from the address, register abbreviation, register name, and resource macro name.

Use the register map index at searching for the register function when designing aresource macro.

(2) Pin function index

The pin function index is similar to the explanation ofthe pin function and it allows serch for the block

diagram of each resource macro, the explanation ofthe pin function, and notes from the package pin

number, pin name, circuit type, and resource macro name. Use the pin function index when creating

the system board, etc. (The pin function index will be provided in the next revision of this manual).

Organization of Notes and Checks

Notes :Reference information is given here. Use this as a hint or note when usingthe MB90M405.

This also gives a section(s) to refer.

Check :Precautions when usingthe MB90M405 are given here. Specification restrictions, etc., are

included.

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 afluorescent

lamp.

As with the original F2MC-8L and F2MC-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, a32-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-timermode (stops everything except original oscillation and time-base timer)

•Stop mode (stops original oscillation)

•CPU Intermittent operation mode

•Package

•QFP-100 (FPT-100P-M06: 0.65 mm pin pitch)

•Process

•CMOS technology

1.2 Resources

•I/O port: 26 pins maximum (All 26 pins can also serve as resource pins).

•18-bit time-base timer: 1 channel

•Watchdog timer: 1 channel

•16-bit reload timer: 3 channels

•16-bit free-run timer: 1 channel

•16-bit output compare: 1 channel

•16-bit input capture: 2 channels

•When the count value of the 16-bit free-run timer matches the setting value of the output compare, the

timer is cleared and an interrupt request is issued.

•Serial I/O: 2 channels

•UART: 2 channels

•Clock-synchronous serial transfer (I/O extended serial) can be used.

•The direction of the shift clock level can be selected arbitrarily (MSB or LSB).

•DTP/external interrupt (4 channels)

•Start extended intelligent I/O services by an external input, and generate an external interrupt.

•Delayed interrupt generation module

•Atask-switching interrupt request is generated.

•8-/10-bit A/D converter (16 channel)

•8- or 10-bit resolution can be selected.

•FL controller

•Enables FL driver control.(The auto display control is performed for 32 digits max. and 59 segments

max.)

1 to 32 digits can be set (can be set on a digit-by-digit basis).

The dimmer can be set.

•Enables LED driver control (Auto display control is performed for 16 segments maximum).

The auto display control can be performed for 16 segments max. at 1/2 duty.

•Timerclock divider

•The original oscillation can be divided by 32, 64, 128, or 256.
