MB90455

16-bit Proprietary Microcontroller

Fujitsu 

MB90455 Series

• 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) (in-

cluding 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

• 16-bit reload timer: 2 channels

• 16-bit input/output timer

- 16-bit free run timer: 1 channel

- 16-bit input capture: (ICU): 4 channels

Interrupt request is issued upon latching a count value of 16-bit free run timer by detection of an edge on pin

input.

• UART 1: 1 channel

• Equipped with full-duplex double buffer

• Clock-asynchronous or clock-synchronous serial transmission is available
