Part 1 – System Interface

RX600 microcontroller was designed with a holistic system level vision. The RX600 uses an Enhanced Harvard architecture to connect to internal 100MHz Flash and internal 100MHz SRAM. There is also a 32-bit external bus connection through Main Bus 1 and there is even an external DMA controller which can act as a bus master for the external bus greatly offloading the CPU. In addition to the Main Bus 1 there is a second Main Bus 2 and six peripheral busses. To help move data around independently there are three more bus masters: the DTC, the DMA, and the Ethernet DMA.

Part 2 – Exception Handling

RX offers tremendous flexibility in configuring interrupts. When an interrupt is configured as a Fast Interrupt with Dedicated General Registers, the latency to enter an interrupt service routine is only 5 cycles and total overhead associated with interrupt handling is only 8 cycles.

Part 3 – Clock Generation

The manner in which clocks are generated affect overall system performance, power, noise, and cost. Watch this short video to learn more about the clock generation capabilities on the RX630 microcontrolle.

Part 4 – Low Power Modes

Designed using low power techniques and offering low power modes, RX is an extremely power efficient microcontroller architecture. Check out this You Tube video for more information.
