Overview
FUJITSU SEMICONDUCTOR DATA SHEET DS07-13728-3E 16-bit Proprietary Microcontroller CMOS F2MC-16LX MB90455 Series MB90F455 (S) /F456 (S) /F457 (S) MB90455 (S) /456 (S) /457 (S) /V495G s 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 F2MC* 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)).

s 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).
(Continued) 48-pin plastic-LQFP s PACKAGE (FPT-48P-M26) 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 •...
