MB91461
DESCRIPTION
MB91461 is a line of the general-purpose 32-bit RISC microcontrollers designed for embedded control applica-
tions such as consumer devices and vehicle system, which require high-speed real-time processing. MB91461
uses the FR60 CPU compatible with the FR family* CPUs.
MB91461 contains the LIN-UART and CAN controller.
* : 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
• Maximum operating frequency : 80 MHz (oscillation frequency 20 MHz, oscillation frequency 4 multiplier (PLL
clock multiplication method))
• 16-bit fixed-length instructions (basic instructions)
• Instruction execution speed : 1 instruction per cycle
• Instructions including memory-to-memory transfer, bit manipulation instructions, and barrel shift instructions:
Instructions suitable for embedded applications
• Function entry/exit instructions and register data multi load store instructions: Instructions supporting C
language
• Register interlock function : Facilitating assembly-language coding
• Built-in multiplier with instruction-level support
Signed 32-bit multiplication : 5 cycles
Signed 16-bit multiplication : 3 cycles
• Interrupt (PC/PS saving) : 6 cycles (16 priority levels)
