SANTA CLARA, Calif. -- November 12, 2012

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 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. 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:

(1) Timer

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 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. 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 layout.

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 notice.)
