SANTA CLARA, Calif. -- April 16, 2013

Renesas Electronics Corporation (TSE: 6723), a premier provider of advanced
semiconductor solutions, has introduced the first in its RX100 Series of
microcontrollers (MCUs) – the RX111 Group, which is the market’s first 32-bit
MCU to feature True Low Power™ as well as fast wake up, zero wait state flash,
multiple safety functions and integrated USB 2.0 host, device and on-the-go
(OTG) support. The new device group extends the True Low Power™ features of
the Renesas 8/16-bit RL78 MCU Series to the 32-bit product line up, offering
greater device scalability. Designed to support a broad range of markets, the
new RX111 devices deliver a combination of ultra low power consumption,
on-chip connectivity and superior performance at attractive price points for
low-end 32-bit embedded applications including mobile healthcare, smart
meters, sensors/detectors, and industrial and building automation.

“Designing for ultra low power, connectivity and robust performance is
essential as more applications, such as mobile health and smart energy, move
toward a smaller energy footprint,” said Peter Carbone, Vice President of
Marketing, Renesas Electronics America. “Leveraging Renesas’ proven process
technology enables our RX100 Series to achieve a leading position in these
areas, bringing True Low Power to the 32-bit world, and providing
state-of-the-art communications, flexible power management and miniaturization
to support these growing 'Smart Society' needs.”

Renesas’ True Low Power capability offers designers the lowest possible power
consumption across the entire temperature and voltage range, including all
peripherals and Flash memory, while also providing maximum flexibility with
multiple operational and sleep modes. This allows for the lowest possible
power consumption for the user’s application environment.

IAR Systems provides support for the RX111 devices in the IAR Embedded
Workbench for Renesas RX compiler and integrated development environment
(IDE). And, as part of an exclusive agreement with Renesas, IAR Systems will
also provide the 64KB free version of its Embedded Workbench for Renesas RX
tools to support all RX devices, including the new RX111 MCUs.

“Performance and efficiency are key factors for embedded developers, and we
have strengthened our partnership with industry-leading Renesas Electronics to
continue supplying developers with the highest performing tools,” said Stefan
Skarin, CEO IAR Systems. “As the only third-party tools provider covering the
entire range of Renesas’ 8-, 16- and 32-bit MCU families, IAR Systems is proud
to announce full support for the RX111 devices in IAR Embedded Workbench. The
high performance scores achieved on the CoreMark benchmarks confirms IAR
Embedded Workbench and the RX100 series as a great choice for customers aiming
to create true low-power, high-performance applications. To give developers an
opportunity to try this powerful combination, we also provide a free
64KB-limited version of the tools.”

With the addition of the RX111 group, the Renesas RX Family offers embedded
designers one of the most comprehensive 32-bit line up that supports a wide
range of applications, from the smallest, battery-powered equipment in which
cost is the most important factor to the highest performance applications that
require extensive data processing and computation.

About the RX100 Series

Based on Renesas’ RX CPU core, the RX100 Series of MCUs delivers high
performance, ultra low power, connectivity and digital signal processing (DSP)
functionality in a general-purpose MCU. The new RX111 devices feature 32MHz
operating speeds and 1.56 Dhrystone MIPS (DMIPS)/MHz throughput, with power
consumption as low as 64 uA/DMIPS. The MCUs also achieve 3.08 CoreMark/MHz and
14.9 CoreMark/mA.

Renesas True Low Power technology delivers flexible power management and
optimum power consumption for all use cases. The RX111 group of MCUs offers
three different run modes, three low power modes and a flexible clock system.
For instance, the Low Power Fast Wakeup capability enables the MCUs to operate
at 100uA/MHz in Run Mode and 350nA in Software standby from which it can
wake-up in only 4.8us. It integrates a Zero Wait State Flash with Erase/Write
as low as 1.8V, 1KB erase block size and background operation (BGO), and offer
erase times as low as 10ms per block. The devices support multiple
communications peripherals, including USB 2.0 host with battery charging,
device and OTG, and the I^2C, and SPI (serial peripheral interface) protocols.
Analog functions include a 12-bit ADC (analog-to-digital converter) with
internal voltage reference, an 8-bit DAC (digital-to-analog converter) and a
temperature sensor.

The RX111 group of MCUs is software compatible with the RX600 and RX200
Series, providing greater flexibility and an easy migration path to higher
performance MCUs. The Rx111 MCUs are available in low pin counts ranging from
36 to 64 pins and 16KB to 128 KB embedded flash memory with roadmap to higher
memory size. As part of the RX Family, the new MCUs also feature compatible
instruction set, hardware and software toolset, peripherals, and hardware
safety features to comply with safety standards, including Cyclic Redundancy
Checks (CRCs), Clock Accuracy Circuit (CAC), independent watch dog timer, a
motor control timer (MTU2) and I/O ports.

Development Ecosystem

Renesas provides a comprehensive development ecosystem for the RX Family,
including e^2studio, a powerful Eclipse-based IDE, as well as compilers,
debuggers, code generation tools and flash programmers. The RX111 devices are
supported by the IAR Embedded Workbench for Renesas RX compiler and IDE. IAR
Systems will provide the 64KB free version of these tools to support all RX
devices, including the new RX111 MCUs.

Pricing and Availability

Samples of the RX111 devices are available now.  Mass production is scheduled
for September 2013 and is expected to reach a scale of 1,000,000 units per
month in April 2014 with pricing ranging from US$1.89 for a 64KB Flash, 48-pin
configuration in 1000-unit quantities to US$2.34 for a 128KB Flash, 64-pin
