Instructions for built-in applications: memory-to-memory transfer, bit processing, barrel shift etc.
Instructions adapted for high-level languages: function input/output instructions, register contents multi-load/
store instructions
Easier assembler notation: register interlock function
Built-in multiplier/instruction level support
Signed 32-bit multiplication: 5 cycles

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
4 GB expanded memory space enables linear access
Instruction compatible with FR30/40 family
Bus Interface
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 64 KB units
Interface support for many memory types
SRAM, ROM/Flash
Page mode flash ROM, page mode ROM interface
Burst mode flash ROM (select burst length 1, 2, 4, 8)
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
Built-in RAM
128 KB built-in RAM capacity
Accepts writing of data and instruction codes, enabling use as instruction RAM
Instruction cache
1 KB capacity
2-way set associative
4-words (16 bytes) per set
Lock function enables permanent program storage

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
Bit search module (using REALOS)
Searches words from MSB for first bit position of a 1/0 change
Reload timer (includes 1 channel for REALOS)
16-bit timer: 3 channels
Internal clock multiplier choice of x2, x8, x32
