DESCRIPTION

The Fujitsu MB91360G series is a standard microcontroller containing a wide range of I/O peripherals and bus control functions. The MB91360G series features a 32-bit RISC CPU (FR50 series) core and is suitable for embedded control applications requiring high-performance and high-speed CPU processing. The MB91360G series also contains up to 4 Kbyte instruction cache memory and other internal memories to improve the execution speed of the CPU. All new members of the MB91360-family are equipped with a new clockmodulator unit which drastically reduces the EME (electromagnatic emission). This feature can bring remarkably advantages to your entire system since redesigns due to EMI-problems can be avoided. The modulation of the internal operation clock reduces the noise by spreading the energy of the MCU over a wide frequency range.

FEATURES

• Execution time : down to 15.6 ns (64 MHz)
• FR50 series CPU : RISC architecture
  
  • The CPU has a general-purpose register architecture with improved numeric implementation whereby a wide range of delayed branch instructions reduces losses in execution time due to pipeline breaks. Bit manipulation instructions and memory access instructions have been enhanced resulting in improved code efficiency and execution speed for control implementation.
  • A five-stage pipeline structure provides high-speed processing (one instruction per cycle) 32-bit linear address space : 4 Gbytes
  • Fixed 16-bit instruction size (basic instructions)
  • High-speed multiplication/step division
  • High-speed interrupt processing (6 cycles)
  • General-purpose registers : 16 x 32 bits
• External bus interface unit with a wide range of functions
  
  • Divides the external memory space into a maximum of eight areas. Chip select signal setting, data bus width selection (8, 16, 32-bit) , and area size can be specified for each area.
  • Address bus up to 32 bit wide
  • Programmable auto-wait function
• Internal instruction cache
  
  • The MB91360G series contains up to 4-Kbyte instruction cache to improve the execution speed of external programs.
  • Two-way set associative caching
• DMAC
  
  • Direct memory access (DMA) can be used to perform various types of data transfer without going via the CPU. This improves system performance.
  • Eight channels (including up to 3 external channels)
  • Three transfer modes supported : single/block, burst, continuous transfer
• Power consumption control mechanisms:
  
  • The MB91360G series contains a number of functions for controlling the operating clock to reduce power consumption.
  • Software control : Sleep and stop/real time clock functions
  • Hardware control : Hardware standby function
  • Gear (divider) function : The CPU and peripheral clock frequencies can be set independently.
• Contains a range of peripheral functions
  
  • UART, U-timer
  • Real Time Clock (with optional subclock operation and subclock calibration module)
  • Stepper Motor Control
  • Sound Generator
  • Serial IO (SIO) , SIO-Prescaler
  • Power Down Reset
  • Alarm Comparator
  • IO-Timer
  • I 2 C Interface
  • 10 Bit D/A Converter
  • CAN Interface
  • 10-bit A/D converter
  • 16-bit reload timer
  • 16-bit PWM timer
  • Watchdog timer
  • Bit search module
  • Interrupt controller
  • External interrupt inputs
  • I/O port function
• Interrupt levels
• 16 maskable interrupt levels
• Other
  
  • Power supply voltage
  • 5 V power supply used, the internal regulator creates internal supply of 3.3 V
  • Package : MB91FV360GA uses a PGA401 package, MB91F362GA is delivered in a QFP208 package.
