MB90246A 16-bit Proprietary Microcontroller

The MB90246A series is a 16-bit microcontroller optimum to control mechatronics such as a hard disk drive unit. The instruction set of F2MC-16F CPU core inherits AT architecture of F2MC*-16/16H family with additional instruction sets for high-level languages, extended addressing mode, enhanced multiplication/division instructions, and enhanced bit manipulati.

Features

• Clock Operating clock can be selected from divided-by-2, 4, 8 or 32 of oscillation (at oscillation of 32 MHz, 1 MHz to 16 MHz). Minimum instruction execution time of 62.5 ns (at machine clock of 16 MHz)
• CPU addressing space of 16 Mbytes Internal addressing of 24-bit External accessing can be performed by selecting 8/16-bit bus width (external bus mode)
• Instruction set optimized for controller applications Rich data types (bit, byte, word, long word) Rich addressing mode (23 types) High code efficiency Enhanced precision calculation realized by the 32-bit accumulator Signed multiplication.
