描述 Description

■DESCRIPTION
The MB91470/480 series is Fujitsu's general-purpose 32-bit RISC microcontroller, which is designed for
embedded control applications that require high-speed processing performance.
This series uses the FR60 CPU, which is compatible with the FR* family of CPUs.
* : FR, the abbreviation of FUJITSU RISC controller, is a line of products of FUJITSU Limited.■FEATURES
•FR60 CPU
 
• 32-bit RISC, load/store architecture, five-stage pipeline
 
• Operating frequency of 80 MHz (PLL clock multiplied)
 
• 16-bit fixed-length instructions (basic instructions)
 
• Instruction execution speed : one instruction per cycle
 
• Memory-to-memory transfer, bit processing, barrel shift instructions, etc. :
    instructions suitable for embedded applications
 
• Function entry and exit instructions, multi load/store instructions of register contents :
    instructions compatible with C language.
 
• Register interlock function to facilitate assembly-language coding
 
• Built-in multiplier/instruction-level support
    •Signed 32-bit multiplication : 5 cycles
    •Signed 16-bit multiplication : 3 cycles
 
• Interrupts (save PC and PS) : 6 cycles, 16 priority levels
 
• Harvard architecture allowing program access and data access to beexecuted simultaneously
 
• Instructions compatible with the FR family
 
• I/O ports
 
• NMI (Non Maskable Interrupt)
 
• External interrupts
 
• Bit search module (for REALOS)
    Function to search for the position of the first bit thathas changed from 1 to 0 in a word starting from the MSB
 
• 16-bit reload timers
 
• Timing generator
 
• 8/16-bit PPG timers
• Multi-function timer
    •16-bit free-run Timer
    •Input capture (Linked to free-run timer)
    •Output compare (Linked to free-run timer)
    •A/D start up compare (Linked to free-run timer)
    •Wave form generator
      Various wave forms are generated by using output compare output, 16-bit PPG timer and 16-bit dead timer.
 
• Base timer
    Only one timer function can be selected from the 16-bit PWM timer, 16-bitPPG timer, 16/32-bit reload timer, and 16/32-bit PWC timer.
 
• 8/16-bit up/down counter
 
• Multi-function serial interface
   
• Full-duplex double buffer
    
• With 16-byte FIFO
   
• Asynchronous (start-stop synchronization) communication, clock synchronous communication, I2C* standard mode (Max 100 kbps), I2C high-speed mode (selectable various modes at maximum of 400 kbps)
   
• Selectable parity On/Off
   
• Each channel has built-in baud rate generator
   
• Error detection function for parity, frame and overrun errors
   
• External clock can be used as transfer clock
   
• With I2C function
• 8/10-bit A/D Converter (Successive comparison type)
 
• Resolution : 8-bit or 10-bit resolution selectable
 
• Conversion Time :  1.2 µs (minimum conversion time for 33 MHz system clock)
                             1.2 µs (minimum conversion time for 40 MHz system clock)
