Renesas Electronics Adds Miniaturization, Power-Savings Enhancements to the RL78 Family of Ultra Low Power Microcontrollers
SANTA CLARA, Calif. --(Business Wire)--
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, here 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.
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' e2studio 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.)
