Cortex-M4 / Renesas SH-Iji Embedded CPU Concept

Cortex-M series / Renesas SH series embedded microcontrollers support high-speed and high-functionality in embedded devices.

Cortex-M Series - Designed for low-power embedded microcontrollers. The M series includes Cortex-M0, Cortex-M3, and Cortex-M4, which can be selected based on application needs. There are many examples, such as motor vector control in home appliances. There are numerous cases as a vector control CPU for three-phase motors. Features of the Cortex-M Series: (Adopted by many semiconductor companies as ARM-based microcontrollers) RISC 32-bit processor, Harvard bus architecture CMSIS (Cortex Microcontroller Software Interface Standard) Versions available with DSP/FPU (hardware computation unit). Thumb2 instruction set (mixed 16/32-bit instruction lengths) NVIC (Nested Vectored Interrupt Controller) Power consumption modes (sleep/deep sleep modes) Common development tools for the series Additional boards are required for LAN, WiFi, Bluetooth, video output, etc.
