Release of the RX62T Group for Energy-Saving Motor and Other Inverter Control Applications

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.

RX CPU core: High-speed, high-performance, and high-code-efficiency

High speed: 100MHz; high performance: 165DMIPS@100MHz (1.65DMIPS/MHz) Built-in multiply-divide unit, multiply-and-accumulate unit, and single-precision floating point unit (FPU)

The RX CPU has achieved a maximum operating frequency up to 200MHz. It is the next-generation CPU core that adopted high-speed features such as 5-stage pipeline, Harvard architecture, out-of-order execution, as well as multiply and accumulate unit, and FPU. With the RX610 Group, high processing performance of 1.65DMIPS at 1MHz (165DMIPS at 100MHz) has been achieved.

Low power consumption

Output current is about 50mA, even at the fastest-speed operation at 100MHz. This translates to 0.5mA per 1MHz, about half that of Renesas’ existing products.
In addition, by optimizing the instruction length of frequently used instructions, an average 30% improvement in code efficiency over existing products is achieved.

Equipped with large-volume high-speed memory

The maximum memory capacity is 2MB flash ROM with a 128KB RAM. The 2MB flash ROM is of high-speed MONOS (Metal Oxide Nitride Oxide Silicon) structure, no wait states at speeds up to 100MHz. Combined with more than 30% improvement in code efficiency compared to Renesas’ existing products, it is highly useful for large-scale applications that require high-speed processing. In addition, a 128KB SRAM and a data flash with 30,000 erase/write cycles are mounted to eliminate the need for external SRAM or EEPROM.

Enhanced built-in functions

In addition to enhanced standard functions such as serial communications and timer, the new products incorporate a variety of popular functions used in existing Renesas products, including DMAC (Direct Memory Access Controller) to perform high-speed data transfer in place of the CPU, DTC (Data Transfer Controller) to make data transfer efficient, and CMT (Compare Match Timer) useful for interrupt and polling.

Lineup:

RX610 Group

The RX610 Group is built around the RX core and has enhanced analog, communication, and timer functions.
The products are equipped with four units of 10-bit A/D converters (1 μs), 10-bit D/A converter, large-capacity memory (2MB flash, 128KB RAM max) capable of single-cycle access at 100MHz, 7 channels of SCI, I2C, 16 channels of 16-bit timer, 4 channels of 8-bit timer, and major functions. They enable a system to be configured without peripheral memory and other peripheral devices, reducing the total cost of the system.

RX621, RX62N Group

The RX621 Group and the RX62N Group are built around the RX core and are equipped with 2 channels of USB 2.0 full-speed (Host, Function and OTG), 2 channels of CAN*, and EtherMAC** as communications interfaces. The products are designed to not put a restriction on applications based on their communication method, and these communication methods can be achieved on a single chip. They are also equipped with a rich set of system fail-safe functions such as power-on reset (POR), low voltage detection (LVD), and an independent watchdog timer. *Optional setting for RX62N Group. **Only available for RX62N Group.

RX62T Group

The RX62T Group of high-performance microcontrollers with a maximum operating frequency of 100MHz are designed for motor control. They are equipped with multifunction timers (MTU, GPT), high-speed 12-bit A/D converter, and 10-bit A/D converter for facilitating motor control.
The products also incorporate many safety features to comply with the IEC60730 safety standard for home appliances. In addition to a maximum of 256KB flash and 16KB RAM on-chip memory, they have a maximum of 32KB of on-chip flash memory for data storage. 64-pin to 112-pin packages are available.
