DESCRIPTION
MB90455 series devices are general-purpose high-performance 16-bit micro controllers
designed for process control of consumer products, which require high-speed real-time processing. The system, inheriting the architecture of F?MC* family, employs additional instruction ready for high-level languages, expanded addressing mode, enhanced multiply- divide instructions, and enriched bit-processing instructions. Furthermore, employment of 32-bit accumulator achieves processing of long-word data (32 bits). The peripheral resources of MB90455 series include the following:
8/10-bit A/D converter, UART 1, 8/16-bit PPG timer, 16-bit input-output timer (16-bit free-run timer, input capture 0, 1, 2, 3 (ICU)). *: "F?MC", an abbreviation for FUJITSU Flexible Microcontroller, is a registered trademark of FUJITSU Ltd.
FEATURES
Clock
Built-in PLL clock frequency multiplication circuit
Selection of machine clocks (PLL clocks) is allowed among frequency division by two on oscillation clock, and multiplication of 1 to 4 times of oscillation clock (for 4-MHz oscillation clock, 4 MHz to 16 MHz).
Operation by sub-clock (8.192 kHz) is allowed.
Minimum execution time of instruction: 62.5 ns (when operating with 4-MHz oscillation clock, and 4-time multiplied PLL clock).
16 Mbyte CPU memory space
24-bit internal addressing
Instruction system best suited to controller
Wide choice of data types (bit, byte, word, and long word)
Wide choice of addressing modes (23 types)
Enhanced multiply-divide instructions and RETI instructions
Enhanced high-precision computing with 32-bit accumulator
Instruction system compatible with high-level language (C language) and multitask
Employing system stack pointer
Enhanced various pointer indirect instructions
Barrel shift instructions
Increased processing speed
4-byte instruction queue
Powerful interrupt function with 8 levels and 34 factors
Automatic data transfer function independent of CPU
Expanded intelligent I/O service function (EI2 OS): Maximum of 16 channels
Low power consumption (standby) mode
Sleep mode (a mode that halts CPU operating clock)
Time-base timer mode (a mode that operates oscillation clock, sub clock, time-base timer and clock timer only)
Clock mode (a mode that operates sub clock and clock timer only)
Stop mode (a mode that stops oscillation clock and sub clock)
CPU blocking operation mode
Process
CMOS technology
I/O port
General-purpose input/output port (CMOS output): 34 ports(MB90F455/F456/F457, MB90455/456/457) (including 4 high-current output ports) (When sub clock is not used, 36 ports(MB90F455S/F456S/F457S, MB90455S/456S/457S))
Timer
Time-base timer, clock timer, watchdog timer: 1 channel
8/16-bit PPG timer: 8-bit x 4 channels, or 16-bit x 2 channels

UART 1: 1 channel
Equipped with full-duplex double buffer
Clock-asynchronous or clock-synchronous serial transmission is available
DTP/External interrupt: 4 channels
Module for activation of expanded intelligent I/O service (EI2OS), and generation of external interrupt.
Delay interrupt generator module
Generates interrupt request for task switching.
8/10-bit A/D converter: 8 channels
Resolution is selectable between 8-bit and 10-bit.
Activation by external trigger input is allowed.
