MCUs in the RX600 series provide features and capabilities geared towards the requirements of embedded system control systems. The MCUs are ideal for processing large high-speed high-efficiency application programs that must be executed at high-speeds. Their RX CPU can access the on-chip flash memory a single cycle at 100MHz and operates at clock speeds up to 200MHz. A single-precision hardware floating-point unit (FPU) and a 32-bit multiplier, divider and MAC allow RX600 series devices to execute filter operations in real time and rapidly process algorithms that implement precise motor control. A memory protection unit will be available as optional features on future RX600 devices.

The inaugural RX600 MCU is a general-purpose device. It offers large-capacity memory, as well as timer, A/D converter and serial interface peripherals compatible with similar functions in existing products.
