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.

The RX600 is the high-speed and high-performance series in the RX family.
The series is positioned as the upward successor to the H8SX and R32C, the 32-bit families of Renesas MCUs.
Already released are the RX610 Group suitable for photocopiers, laser beam printers, home audio systems, and so on, and the RX621 Group and RX62N Group suitable for networking equipment with enhanced connectivity and fail-safe functions. Now, the RX62T Group, which is suitable for energy-saving motor and other inverter control applications, has been released.
Looking forward, Renesas will enhance the series by reinforcing the memories, packages, and peripheral functions focusing on applications for telecommunications, motor control, etc.
