32-bit RISC Microcontroller
CMOS
FR30 Series
DS07-16301-2E
MB91101/MB91101A
s DESCRIPTION
The MB91101 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 support the vast memory space accessed by the 32-bit
CPU, the MB91101 normally operates in the external bus access mode and executes instructions on the internal
1 Kbyte cache memory and 2 Kbytes RAM for enhanced performance.
The MB91101 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 50 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

Circuit

Function
F 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 a I/O port when SO2 and OCPA2 are not
used.
This function is available when UART2 data output is disabled.
F PWM timer output pin
This function is available when PWM timer output is enabled.
Can be configured as a I/O port when OCPA0 and ATG are not
used.
This function is available when PWM timer output is disabled.
External trigger input pin for A/D converter
This pin is used for input when external trigger is selected to
cause A/D converter operation, and it is necessary to disable
output for other functions from this pin unless such output is
made intentionally.
D Analog input pins of A/D converter
This function is available when AIC register is set to specify
analog input mode.
— Power supply pin (VCC) for A/D converter
— Reference voltage input (high) for A/D converter
Make sure to turn on and off this pin with potential of AVRH or
more applied to VCC.
— Power supply pin (VSS) for A/D converter and reference voltage
input pin (low)
— 5 V power supply pin (VCC) for digital circuit
Always two pins must be connected to the power supply
(connect to 3 V power supply when operating at 3 V).
— Bypass capacitor pin for internal capacitor.
Also connect this pin to 3 V power supply when operating at
3 V.
— Earth level (VSS) for digital circuit
*1: FPT-100P-M05
*2: FPT-100P-M06
Note: In most of the above pins, I/O port and resource I/O are multiplexed e.g. P82 and BRQ. In case of conflict
between output of I/O port and resource I/O, priority is always given to the output of resource I/O.
