MB91F109 Datasheet 32-bit Risc Microcontroller

Manufacturer: Fujitsu Semiconductor Limited

Overview: .. FUJITSU SEMICONDUCTOR DATA SHEET DS07-16304-1E 32-bit RISC Microcontroller CMOS FR Family.

General Description

The MB91F109 is a standard single-chip microcontroller constructed around the 32-bit RISC CPU (FR* family) core with abundant I/O resources and bus control functions optimized for high-performance/high-speed CPU processing for embedded controller applications.

To carry out hi-speed performance of CPU instructions, instruction/data Flash memory of 254 Kbytes and RAM of 2 Kbytes + 2 Kbytes are embedded in the MB91F109.

The MB91F109 is optimized for applications requiring high-performance CPU processing such as navigation systems, high-performance FAXs and printer controllers.

Key Features
