Outline Specification of CPU

The outline specification of CPU is explained.
Outline Specification of CPU
2
The F MC-16LX CPU core is the 16-bit CPU designed for applications requiring the high-speed real-time
process for house hold device, etc. The F
enabling the high-speed and high-efficiency control process.
2
The F MC-16LX CPU core allows processing not only the 16-bit data but also the 32-bit data by
containing internal 32-bit accumulator (some instructions enabling the 32-bit data process). Maximum
16 Mbytes (extensible) memory space can be accessed by the linear pointer or the bank method. In
addition, the instruction system based on the F
instruction compatible to the "H" level language, the extended addressing mode, the enhanced
multiplication and division instructions, and the enriched bit process. Next, the feature of F
CPU is shown.
Minimum instruction execution time
• 41.7 ns / 6 MHz original oscillation four-time multiplication (at 24 MHz / 3.3 V ± 0.3 V internal
operation)
• PLL clock multiplication method
Maximum memory space: 16 Mbytes accessed by the linear/bank method
Instruction system optimized to control usage
• Data type which can be handled: Bit/byte/word/longword
• Standard addressing mode: High-precision operation enhanced by the employed 23 types/32-bit
• Signed multiplication and division, and enhanced RETI instructions
Strong interrupt function: Eight propriety levels (programmable)
Automatic forwarding function which is independent from the CPU
• Extended intelligent I/O service function from maximum 16 channels
• µDMAC from maximum 16 channels
Instruction system that supports "H" level language (C language) multitasking
• Adoption of system stack point/Instruction set symmetry/barrel shift instruction
Higher execution speed: 4 byte cue
