Renesas Electronics, a premier supplier of advanced semiconductor solutions, today announced the expansion of the lineup of the 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.
Key Features of the new RX63T Group of MCUs
1) Timer
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 a 16-bit, general-purpose PWM timer (GPT) capable of driving a 3-phase motor. The GPT can independently control four channels of single phase inverter.
The timer uses the same clock as the CPU at 100 megahertz (MHz). This enables it to achieve a wide range of width measurements for PWM output waveforms with resolutions as small as 10 nanoseconds (ns).
2) Motor vector control
The new RX63T MCUs reduce the cost and increase usability of motor vector control applications. They feature two 12-bit A/D converter units, which can capture analogue input values with a minimum conversion time of one microsecond (µs).
3) A/D converters
The 12-bit A/D converters can easily be used for sensorless vector control methods, such as three-shunt or single-shunt current detection, as the simultaneous sampling of three input channels is available. Continuous A/D conversion is supported by the double data registers installed in the 12-bit A/D module.
The 12-bit A/D includes three programmable gain amplifiers and three window comparators. This eliminates the need for external operational amplifiers and comparators used for overcurrent and overvoltage protection. Elimination of these external components reduces system cost and simplifies PCB layout.
The new RX63T also include a 10-bit A/D converter unit that can capture analogue input values with a minimum conversion time of 0.5µs.
The RX63T group of MCUs also incorporates many safety features that help to meet safety standards such as IEC60730. These include an independent watchdog with its own on-chip clock source (IWDT). The new RX63T also supports USB 2.0 host/device/OTG, CAN connectivity and a single-precision floating-point unit (FPU).
To help customers shorten the development cycles of new embedded systems, Renesas' third-party suppliers and Alliance Partner networks support the RX MCUs with a variety of hardware and software tools.
The devices in the new RX63T group provide a scalable memory solution from 256KB flash to 512KB flash with up to 48KB of embedded SRAM. They also include an additional independent 32KB of data flash memory with a background operation (BGO) function that enables data to be written while a program is executing. The embedded flash memory is based on Renesas' proven MONOS (metal oxide nitride oxide silicon) technology that can be accessed without wait state insertion. This enables a maximum performance level of 1.65 DMIPS/MHz at any CPU frequency, without any limitation from flash technology. These products will be offered in 100-pin, 112-pin, 120-pin and 144-pin LQFP packages.
Please refer to the separate sheet for the main specifications of the RX63T group of MCUs.
Availability
Samples of the RX63T group of MCUs will be available from the end of November 2012. Mass production of the RX63T devices is scheduled to begin at the end of May 2013 and is expected to reach a scale of 400K units per month in March 2014. (Availability is subject to change without notice.)
