Bus Interface
Built-in RAM
Instruction cache
DMAC (DMA controller)
Bit search module (using REALOS)
Reload timer (includes 1 channel for REALOS)
• Easier assembler notation: register interlock function
• Built-in multiplier/instruction level support
• Interrupt (PC, PS removal): 6 cycles, 16 priority levels
• Harvard architecture for simultaneous execution of program access and data access
• CPU hold 4-word queue allows advanced instruction fetch function
• 4G bytes expanded memory space enables linear access
• Instruction compatible with FR30/40 family
• Operating frequency: Max 33 MHz
• 8- or 16-bit data output
• Built-in pre-fetch buffer
• Unused data/address pins can be used as general-0purpose input/output ports
• Fully independent 8-area chip select outputs, can be set in minimum 64K bytes units
• Interface support for many memory types
• Basic bus cycle: 2 cycles
• Programmable by area with automatic wait cycle generation to enable wait insert
• RDY input for external wait cycles
• DMA supports fly-by transfer with independent I/O wait control
• 128K bytes (MB91307R), 64K bytes (MB91306R)
• Accepts writing of data and instruction codes, enabling use as instruction RAM
• 1K bytes capacity
• 2-way set associative
• 4-words (16 bytes) per set
• Lock function enables permanent program storage
• Areas not used for instruction cache can be used for RAM
• 5-channel (3-channel external-to-external)
• 3 transfer sources (external pin, internal peripheral, software)
• Addressing mode with 32-bit full address indication (increment, decrement, fixed)
• Transfer mode (demand transfer / burst transfer / step transfer / block transfer)
• Fly-by transfer support (3 channels between external I/O and external memory)
• Transfer data size selection 8/16/32-bit
• Searches words from MSB for first bit position of a 1/0 change
• 16-bit timer: 3 channels
• Internal clock multiplier choice of x2, x8, x32
Signed 32-bit multiplication: 5 cycles
