NEC Electronics Supports Automotive Audio and Navigation Control Systems with New 32-Bit Microcontrollers
(Wireless News Via Acquire Media NewsEdge)
NEC Electronics, a 32-bit microcontroller supplier, has reaffirmed its
commitment to the automotive market by expanding support for audio and
navigation applications with its new V850E/Sx3-H microcontrollers
(MCUs).
Based on the company's V850E1 core, the new V850E/Sx3-H devices offer
flash memory capacity for 32-bit MCUs, in addition to improved CPU
performance for today's audio and infotainment systems. The
improvements, together with a small 0.5 millimeter pin-pitch QFP
package, make the new devices ideally suited for use in
high-functionality, high-performance automotive radios, compact disc
systems, DVD systems, USB/SD card readers and digital terrestrial
broadcast equipment, the company said.
"In car audio and navigation systems, we are seeing a migration toward
consumer electronics-based technologies such as USB, SD card and
Bluetooth, in response to growing user demands for smooth transitions
between in-car and out-of-car experiences," said Shinichi Iwamoto, vice
president, microcomputer operations unit, NEC Electronics "In turn, car
manufacturers are demanding MCUs with more built-in memory capacity and
lower radiated noise to support the significant increase in software
that these media require. Our new V850E/Sx3-H devices enable automotive
designers to meet these goals, offering industry-leading memory
capacity and improved CPU performance while adhering to strict
reliability constraints."
Augmenting the company's existing V850ES/SG3 and V850ES/SJ3 MCUs, the
newest devices in NEC Electronics' S Series consist of two lineups: the
V850E/SJ3-H and the V850E/SK3-H. In addition to 1.5 megabytes (MB) of
flash memory, 1.5 times more capacity than V850ES/Sx3 devices, the
V850E/Sx3-H MCUs can execute 85 Dhrystone MIPS at a clock speed of 48
megahertz (MHz), compared to 32 MHz by existing devices. These
improvements allow the MCUs to store more software for system control
while speeding up software execution time, the company said.
For improved reliability, according to the company, integrated built-in
spread spectrum clock generators (SSCG) reduce the MCU clock's
oscillation (fundamental) and higher frequencies, which helps to reduce
the risk of degraded radio performance and chip errors. This also
decreases the resources required to evaluate and investigate
electromagnetic interference (EMI) in anti-EMI components, allowing
designers to lower system development costs and shorten development
time. Pin layouts and software in the new devices are backward
compatible with those in V850ES/SG3 and V850ES/SJ3 models, making it
easy for design engineers to leverage existing design assets to avoid
incurring additional costs. Serial interface channels include eight
UART channels, eight CSI channels and six I2C channels that allow
designers to support a larger number of media types, the company noted
in a release.
