MB91F109
s 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, in-
struction/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.
*: FR Family stands for FUJITSU RISC controller.
s FEATURES
FR CPU
• 32-bit RISC, load/store architecture, 5-stage pipeline
• Operating clock frequency: Internal 25 MHz/external 25 MHz (PLL used at source oscillation 12.5 MHz)
• General purpose registers: 32 bits × 16
• 16-bit fixed length instructions (basic instructions), 1 instruction/1 cycle
• Memory to memory transfer, bit processing, barrel shifter processing: Optimized for embedded applications
• Function entrance/exit instructions, multiple load/store instructions of register contents, instruction systems
supporting high level languages
• Register interlock functions, efficient assembly language coding
• Branch instructions with delay slots: Reduced overhead time in branch executions

Function
E UART1 data output pin
This function is available when UART1 data output is enabled.
PWM timer external trigger input pin
This function is available when PF4, UART1 data outputs are
disabled.
Can be configured as general purpose I/O port when SO1 and
TRG3 are not used.
This function is available when UART1 data output is disabled.
E UART2 data input pin
This pin is used for input during UART2 is in input operation,
and it is necessary to disable output for other functions from
this pin unless such output is made intentionally.
PWM timer output pin
This function is available when PWM timer output is enabled.
Can be configured as general purpose I/O port when SI2 and
OCPA2 are not used.
E UART2 data output pin
This function is available when UART2 data output is enabled.
PWM timer output pin
This function is available when PWM timer output is enabled.
Can be configured as general purpose I/O port when SO2 and
OCPA2 are not used.
This function is available when UART2 data output is disabled.
E PWM timer output pin
