Renesas Electronics Enhances the Scalability of RX MCU Family for High-performance Motor Control with Larger Pin Count, Flash and RAM, Enhanced Safety Features for IEC60730 and USB 2.0 Interface
SANTA CLARA, Calif. --(Business Wire)--
Renesas Electronics Corporation (TSE: 6723), a premier provider 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 and also expand the
functions that they feature, such as USB 2.0, 10-bit D/A converter, and
faster ADC (News - Alert) 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

With the new RX63T products, Renesas can offer the best fit solution for
advanced motor control from 1 to 3-motors, i.e. existing small pin-count
RX63T for 1-motor, RX62T for 2-motors and this new RX63T with high
pin-count for 3-motors.
The RX63T platform is built around the high-performance 32-bit RX CPU
core featuring 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, result in 54 individual
products for the RX63T Group in total.
As an expansion of the RX62T and RX63T small pin-counts lineup, the new
RX63T products underline Renesas' contribution to industrial motor and
high-end consumer electronics. The new RX63T maintains a close
compatibility with RX62T and RX63T small pin-counts products, allowing
current customers to migrate to higher versions of their RX62T and RX63T
designs easily 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:
New RX63T MCUs include multi-function timer pulse unit 3 (MTU3)
specialized for 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
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. It features two 12-bit A/D converter units
that can capture analog 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 simultaneous sampling of three input channels is possible. 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 external operational amplifiers and
comparators used for overcurrent and overvoltage protection. Elimination
of these external components reduces system cost and simplifies PCB
The new RX63T have also a 10-bit A/D converter unit that can capture
analog input values with a minimum conversion time of 0.5 µs.
The RX63T Group of MCUs also incorporates many safety features which
help to meet safety standards e.g. IEC60730, such as an independent
watchdog with its own on-chip clock source (IWDT) and so on. 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 256 KB flash to 512 KB flash with up to 48 KB of embedded SRAM.
They also include an additional independent 32 KB 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.
Pricing and Availability
Samples of the RX63T Group of MCUs are available from the end of
November 2012, priced at US$4.10 per unit in 10K unit quantities (This
price is an example of an RX63T MCU with 256K/24K, LQFP100, 3V, no CAN).
Mass production of the RX63T devices is scheduled to begin in the end of
May 2013 and is expected to reach a scale of 400K units per month in
March 2014. (Pricing and availability are subject to change without
