Renesas Electronics enhances the scalability of RX MCU family for high-performance motor control

November 12, 2012 // By Paul Buckley
Renesas Electronics is expanding the lineup of the company’s RX63T group of microcontrollers (MCUs). The new RX63T MCUs have higher pin counts and larger memory versions.

They also expand the functions that they feature, such as USB 2.0, a 10-bit D/A converter, and faster ADC with a minimum conversion time of 0.5 microseconds (µs), and increase the number of channels of timers and serial I/Fs. The new RX63T also inherits the features of the RX62T and existing RX63T. The new MCUs help to reduce system costs and power consumption in applications like industrial motor control, air conditioners, washing machines and solar inverter solutions.

With the new RX63T products, Renesas can offer the best fit solution for advanced motor control from 1 to 3 motors, i.e. the existing small pin-count RX63T for 1 motor, the RX62T for 2 motors and this new RX63T with a high pin-count for 3 motors.

The RX63T platform is built around the high-performance 32-bit RX CPU core featuring a 100 MHz operating frequency with zero-wait-state flash to achieve an outstanding 165 Dhrystone MIPS (DMIPS) performance and 312 CoreMark score. All RX63T and RX62T MCUs include a built-in floating point unit (FPU) and DSP functionality that make them ideal for the intense computation required to implement sensorless vector control and advanced motor control algorithms.

The new RX63T group adds 48 individual products, resulting in 54 individual products for the RX63T group in total.

As an expansion of the RX62T and RX63T small pin-count lineup, the new RX63T products underline Renesas' contribution to industrial motor and high-end consumer electronics. The new RX63T maintains close compatibility with the RX62T and RX63T small pin-count products, allowing current customers to easily migrate to higher versions of their RX62T and RX63T designs with the new RX63T.

As part of the RX family of products, the RX63T comes with comprehensive support, tools and a software ecosystem aimed at facilitating hardware design and software development.

The new RX63T MCUs include a multi-function timer pulse unit 3 (MTU3), specialized in motor control, that can drive up to two 3-phase motors and
