The first 32-bit SuperH RISC device was introduced in 1993.
In the years since, this popular product line has continuously grown
and steadily evolved. Today it encompasses ten major product
families, with more in development. They continue a solid
technology roadmap of innovation fine-tuned to meet the changing
needs of designers of embedded systems for diverse global markets.
A steadfast goal throughout the history of the SuperH family
has been to produce microcomputers [microcontrollers (MCUs) and
microprocessors
(MPUs)]
that
deliver
optimum
mixes
of performance and functionality, achieve requisite levels of
performance at low power, and have compact packages. We also
work to ensure that SuperH devices are offered at competitive prices
and are supported by a comprehensive suite of Renesas hardware
and software development tools. Importantly, we maintain code
compatibility throughout the product line to facilitate software
reuse that saves development time and engineering cost.
Renesas offers SuperH MCUs for general-purpose applications and
SuperH MPUs for specialized applications. The MCUs in our SH-1,
SH-2, SH2-DSP, and SH-2A series for general-purpose embedded
system use offer CPU performance up to 480 MIPS and have
reliable, high-capacity flash memory that is easy to use and
simplifies system designs. The MPUs in our SH-3, SH3-DSP, SH-4,
and SH-4A series for specialized applications deliver performance
levels up to 1080 MIPS and provide on-chip peripherals tailored for
leading-edge applications in automotive, mobile, and PC/AV
markets, among others. Support for SuperH MCUs and MPUs is
comprehensive, encompassing development tools, operating
systems, drivers, middleware, and other products and services from
Renesas and a large international community of technology partners
and third-party vendors. This support facilitates the rapid
development of SuperH-based products and solutions.
Renesas SH-Mobile application processors are used in tens of
millions of mobile phones for offloading the processing
of multimedia content from the main CPU. This baseband-
independent design approach facilitates the rapid evolution of cell
phones and other portable devices that can handle innovative new
communication services and features without impacting the
implementation of proven protocol processing methods. Beyond
those markets, highly versatile SH-Mobile devices suit an
expanding array of products that require smooth audio/video
capture and playback, fast processing for software stacks, flexible
connectivity options, and small form factors.
SH-Mobile devices perform master or co-processor roles, or both.
All have powerful superscalar SH4A-DSP cores that readily handle
JPEG, MPEG-1 Audio Layer 3 (MP3), and MPEG-4 data.
The chips also provide extensive peripheral functions. For example,
a built-in H.264 video engine achieves a 200% performance
increase on average for most middleware, allowing reductions in
CPU speed and power consumption.
Renesas supports SH-Mobile multimedia application processors
with system development platforms, HW/SW tools and other
resources. Additionally, the 200+ members of the SH-Mobile
Consortium from around the world offer middleware, operating
systems, board support packages, system integration assistance,
and application support. Their technologies and services help speed
time-to-market for complete system designs.
The SuperH family of MCUs and MPUs serve a wide range of
embedded systems. The table on the next page summarizes key
applications of each device series.
