SANTA CLARA, Calif. -- November 13, 2012

Renesas Electronics Corporation (TSE:6723), a premier supplier of advanced
semiconductor solutions, today announced the release of the RL78/G1C Group of
microcontrollers (MCUs), which are the industry's first 16-bit MCUs that
conform to the USB Battery Charging Specification, Revision 1.2 and provide
USB host/function interfaces.

The battery charging function of the new RL78/G1C conforms to the USB BC 1.2
standard, which enables high speed charging up to 1.5 A. Furthermore, by
adopting the RL78 core, which features the lowest power consumption class in
the industry, power consumption during USB operation is reduced by about 60%
[Note 1].

“The proliferation of feature-rich connected devices is driving greater demand
for improved battery life and charging capabilities, and the USB standard
offers several benefits to meet these evolving needs,” said Ritesh Tyagi,
senior director, Microcontroller Products & Solutions Marketing, Renesas
Electronics America Inc. “With our MCU design and USB technology expertise,
Renesas is uniquely positioned to deliver innovative solutions, like the new
RL78/G1C Group of MCUs, that incorporate these embedded connectivity and power
demands for Smart Society applications.”

The USB interface is not only used between PCs and PC peripheral equipment,
but is also used as a convenient general-purpose interface for consumer and
industrial equipment in a wide range of areas such as smartphone accessories,
portable healthcare devices, AV accessories, game equipment and industrial
equipment. Recently, the needs for charging from a USB terminal have been
increasing. However, USB ports as defined in the earlier USB 2.0 standard
could not use currents in excess of 500 mA and, as a result, cannot support
high-speed charging. Thus support for the USB BC 1.2 standard, which allows
currents of up to 1.5 A to be used, is strongly desired.

The first series within the RL78/G1C Group of MCUs will feature 32 to 48-pin
devices in packages down to 5 x 5mm, and up to 32KB of flash and 5.5KB of on
board RAM. The RL78/G1C also integrates a 1% accurate high-speed oscillator.
Renesas is moving forward aggressively with the new RL78 series product
deployments. At the same time as being able to contribute to lower power
consumption in end products, with the new RL78/G1C Group of MCUs, Renesas now
provides an extensive lineup that supports the addition of products that
include USB battery charging functionality.

Key Features of the RL78/G1C Group of MCUs:

(1) Industry’s first USB BC 1.2 compliance enables high-speed charging and
power supply control while performing USB communication.

These MCUs include USB ports that conform to the USB BC 1.2 standard that
allows currents up to 1.5 A to be used during charging [Note 2]. This enables
USB communication and high-speed charging concurrently.

(2) Extremely low power consumption achieved by the adoption of the RL78
Family

By adopting the RL78 core, which achieves both low power and high performance,
the RL78/G1C MCUs achieve 71 µA/MHz in full operation and just 0.23 µA in Stop
Mode (RAM retained)

(3) Inclusion of USB host functionality allows support of a wide range of
applications

These new MCUs include both USB host and function supporting both full-speed
and low-speed USB communication. Thus they can support systems that take
advantage not only of USB memory, but widely available peripherals such as
keyboards and mouse.

The RL78/G1C Group of MCUs is optimal for a wide range of applications,
including industrial equipment such as data loggers, consumer equipment such
as smartphone accessories, portable healthcare devices, USB chargers and AV
accessories.

(4) Member of the extensive RL78 Family with USB capability

These new products are the first RL78 Family MCUs that include USB
host/function and can be easily deployed in existing systems that use other
RL78 Family products. The integration of USB functionality alongside RL78’s
smart peripherals allows reduced bill of materials (BOM) whilst contributing
to lower costs and miniaturisation in end products.

[Note 1] When compared to the current consumption of the existing Renesas
R8C/3xU and 78K0R/KC3-L, in the state where USB peripheral communication is
being performed.

[Note 2] In battery charging using a USB connector, the USB port VBUS pin
current is used. The USB BC 1.2 standard defines a mechanism that detects
whether or not the port of the connected device supports high power charging,
so that the portable device can control the current value used for charging.
This allows a maximum of 1.5 A to be used during charging.

Pricing and Availability

Samples of the RL78/G1C Group of MCUs are available now, prices vary by USB
peripheral functions and USB host functions including packages and number of
pins. For example, the 32-pin LQPF package R5F10KBCAFP device with USB
peripheral function is priced at US$1.00 per unit, in 10K-unit quantities.
Mass production of the RL78/G1C devices is scheduled to begin in March 2013
and is expected to reach a scale of 1,000,000 units per month in March 2014.
(Pricing and availability are subject to change without notice.)
