■ 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 be executed simultaneously

• Instructions compatible with the FR family
