Performance without Sacrifice
The RX architecture is future oriented and feature rich. It's driven by a Renesas technology roadmap that focuses on the global environment and anticipates the enormous gains in sophistication that microcontroller-based products are expected to achieve in the next 10 to 20 years. Thus, the RX family of microcontrollers (MCUs) delivers superior performance in terms of core processing performance, code efficiency, and power consumption. An extensive portfolio of on-chip mixed-signal peripherals is available, and fast 90nm Flash memory is embedded. That Flash unleashes full CPU performance, feeding instructions to the 32-bit RX CPU with no delays – no waits, no stalls – maintaining the MCU's peak performance of 165 DMIPS. Memory acceleration isn't required, and the result is just pure, predictable performance.
The Core Difference
These next generation microcontrollers based on the revolutionary RX CPU core enable a new class of MCUs blending the best traits of RISC and CISC MCU architectures while adding DSP and floating point math capability.
This hybrid Digital Signal Controller approach meets the demands of today's embedded applications requiring high performance yet very low power consumption; the smallest possible code and data size; the lowest cost; and the need for digital signal processing.
Drawing from a rich heritage of existing CPU cores from the world's #1 MCU supplier, the RX CPU core design leads the industry for performance and capability in embedded MCUs. There are two compatible RX series to best match your needs starting with RX600 for extreme performance and connectivity, followed by RX200 for ultra-low power applications. Tools, firmware libraries, and documentation make it easy to migrate to RX from any other MCU platform, or to start a new RX design.
RX Family Product Portfolio
The RX family currently consists of two extensive product series. MCUs in the RX600 series are optimized for applications requiring high-performance, high-efficiency processors. Devices in the RX200 series being introduced will expand the range of compatible system-design choices, adding smaller, lower power devices with fewer pins.
Migration from existing Renesas architectures to RX solutions is easy. And, of course, moving designs among RX family members is very easy, since RX600 and RX200 MCUs share the same CPU architecture and peripherals. This gives system engineers valuable design flexibility and provides substantial head starts on reusing software assets. New products for niche markets can be created quickly and efficiently, as can upgraded or simplified versions of existing products for addressing changes in customer preferences.
Comprehensive On-chip Peripherals
To save cost, simplify system designs, reduce total system power consumption, and enable the implementation of value-added features, a wide range of on-chip peripheral functions is clustered around the powerful CPU core of RX MCUs. Broadly categorized into analog, timer, communication and system functions, these numerous peripherals are proven designs delivering impressive performance. The many different types of RX MCUs offer diverse sets of functions, so chip capabilities and cost can be matched to application needs. The devices in the RX621/62N and RX62T product groups exemplify this diversity and optimization.
RX621/62N MCUs provide extensive communication peripherals with options for Ethernet, CAN, and up to two USB-FS 2.0 channels, each operating as USB Host, USB Device, or USB OTG (On the Go). Additionally, they offer up to six SCI, two SPI, and two I2C serial channels. Among their other peripherals are analog interfaces; timers; RTC and POR/LVD functions; and more.
RX62T MCUs provide improved motor/inverter control timers and enhanced analog peripherals for implementing very precise motor control and positioning applications. The MTU3 and GPT timer peripherals enable one MCU to control three motors simultaneously. An FPU and improved analog functions make these MCUs ideal for use with three-shunt or single-shunt vector-type motor control methods.
