SANTA CLARA, Calif. -- April 17, 2013

Renesas Electronics Corporation (TSE:6723), a premier supplier of advanced
semiconductor solutions, has developed the RL78/G10 Group as low pin count
versions of the RL78/G1x Series of microcontrollers (MCUs) that feature
excellent low-power operation as well as superb processing performance with
on-chip flash memory capacities from 1 to 4 KB in 10-pin SSOP (Shrink Small
Outline Package) and 16-pin SSOP packages. These MCUs are optimal for consumer
products such as small appliances.

“The demand for finer control and greater power efficiency in increasingly
smaller form factors is driving a shift from traditional switches to low pin
count MCUs,” said Ritesh Tyagi, senior director, Microcontroller Products &
Solutions Marketing, Renesas Electronics America Inc. “Our RL78/G1x Series of
MCUs continues to deliver superior power, performance and pricing for
customers designing for areas like consumer and household appliances, and we
are pleased to offer the RL78/G10 as an expansion to address these changing
customer needs as the miniaturization in these markets continues.”

The new products inherit the superlative features of the RL78 Family, which
include the industry's lowest level of power consumption and the ability to
reduce total system costs by taking advantage of the peripheral functions
integrated with the MCU itself. Furthermore, the new products feature reduced
operating current (46 uA/MHz – 20 MHz basic operation) by about 30 percent
compared with existing Renesas’ RL78/G13 Group of MCUs (66 uA/MHz – 32 MHz
basic operation), by improvements such as optimization of the inner wiring.

Since consumers are now demanding high functionality in miniature devices,
such as electric toothbrushes and electric razors, that were previously
controlled by simple mechanical switches or logic circuit, finer control is
now required in these products. Furthermore, there are increasing needs for
even lower power consumption associated with battery drive in the miniature
electronic equipment market, which requires these low pin count MCUs.

To respond to these needs, the new RL78/G10 Group low pin count MCUs in the
RL78/G1x Series offers low power consumption and maintains the key peripheral
functions of the RL78 Family in low pin count packages.

Key Features of the RL78/G10 Group of MCUs:

(1) Ultra-low-power consumption (46uA/MHz – 20MHz basic operation) contributes
to lengthening battery life and smaller form factor products.
Designers can choose batteries with smaller capacity and smaller shape, thus
the new products contribute to reducing product size.

(2) The small size of the package – down to 3.6mm x 4.4mm – allows the
RL78/G10 MCUs to be retro fitted for small consumer products.
The RL78/G10 group is suitable for low-power, low-cost consumer products such
as electric toothbrushes with battery drive. The new product facilitates
replacement of mechanical components and adds new intelligent features, such
as power optimization, battery monitoring and sensor management.

(3) The accurate high-speed on-chip oscillator (OCO) allows reduced system
cost.
The integrated high-speed OCO incorporated in the new product eliminates the
requirement for an external oscillator for many consumer electronic devices.

(4) As a controller of power ICs, the new device reduces system power
consumption.
A complicate system with multiple power sources requires a power IC to control
the power activation sequence. The power IC requires control from outside. The
new ultralow power consumption RL78/G10 Group reduces such a system’s power
consumption by controlling the power IC. Renesas provides a kit solution with
power ICs, including Renesas’ RAA23021x series.

Renesas Electronics also provides a robust development environment for the
RL78 Family. This includes Renesas’ e^2studio integrated development
environment (IDE) and the low-cost E1 on-chip debugger, which also functions
as a flash programmer. In addition, Renesas partner companies continue to
expand ecosystem options with a wide variety of hardware and software
development tools for the RL78 Family. This includes the IAR Systems Embedded
Workbench IDE and optimized C/C++ compiler and debugger

Pricing and Availability

Samples of the 10-pin SSOP of the RL78/G10 Group of MCUs are available now,
priced at US$0.29 per unit in 10,000-unit quantities for the 10-pin SSOP with
2 KB Flash. Mass production of the RL78/G10 devices is scheduled to begin in
June 2013 and is expected to reach a scale of 1,000,000 units per month in May
2014. Samples of the 16-pin SSOP devices will be available in the end of 2013.
(Pricing and availability are subject to change without notice.)
