■ DESCRIPTION
The MB91265A series is a 32-bit RISC microcontroller designed by Fujitsu Microelectronics for embedded control applications which require high-speed processing.
The CPU is used the FR family* and the compatibility of FR60Lite.
MB91267NA/F267NA loads the C-CAN (1 channel) .
* : FR is the abbreviation of FUJITSU RISC controller.
■ FEATURES
• FR60Lite CPU • 32-bit RISC, load/store architecture with a five-stage pipeline • Maximum operating frequency : 33 MHz (oscillation frequency 4.
192 MHz, oscillation frequency 8-multiplier (PLL clock multiplication method) • 16-bit fixed length instructions (basic instructions) • Execution speed of instructions : 1 instruction per cycle • Memory-to-memory transfer, bit handling, barrel shift instructions, etc.
: Instructions suitable for embedded applications • Function entry/exit instructions, multiple-register load/store instructions : Instructions adapted for C-language • Register interlock function : Facilitates coding in assembler.
• Built-in multiplier with instruction-level support • 32-bit multiplication with sign : 5 cycles • 16-bit multiplication with sign : 3 cycles • Interrupt (PC, PS save) : 6 cycles, 16 priority levels • Harvard architecture allowing program access and data access to be executed simultaneously • Instruction compatible with FR family (Continued)
