The 15th China Hi-Tech Fair was held at the Shenzhen Convention and Exhibition Center a few days ago. At this exhibition, ROHM displayed many cutting-edge key components that could meet market demands, including the ability to contribute to the energy efficiency and energy conservation of all electronic devices Analog power supply IC; SiC power components that are more energy-efficient and compact than conventional Si; all devices from smartphones, wearable terminals to HEMS can achieve low power consumption, thus enabling easy and convenient life communication & Control technology; from consumer electronics to LED lighting and industrial equipment, making the device have a highly intelligent MCU; and ultra-small elements such as resistors, transistors and diodes that enable the miniaturization and high performance of electronic equipment Device. Demonstrates the rich and extensive product line and strong technical strength of ROHM Group.

ROHM has a rich semiconductor product line, ROHM products have been active in various electronic products, the application field covers the entire electronic world, such as smart phones, tablets, smart TVs, home appliances, automobiles, industry, etc., high performance and miniaturization are two major Significant advantage. ROHM's LED intelligent lighting and wireless power supply solutions at this exhibition have combined many ROHM's innovative technologies. Its powerful technical advantages, extremely low overall cost, and convenient application have attracted a lot of attention.
LED Smart Lighting
At this stage, LED lighting not only needs to have energy-saving performance, but also needs to have rich dimming and toning functions. Under this background, ROHM Group is actively working on LED lighting related business areas. LAPIS Semiconductor takes full advantage of the multiplication effect with the LED technology owned by ROHM, and is committed to developing the best microcontroller for LED lighting control, giving full play to ROHM's advantages, providing high-quality LED driver module solutions and technical support services, and also for The customer prepared the supporting reference board and software development environment.
The 8-bit low-power microcontroller "ML610Q111 / ML610Q112" for LED lighting not only can achieve rich colors and brightness through fine control, but also has a 6-channel PWM port that can control multiple LEDs at the same time, not only white and warm yellow Monochrome LEDs are independently controlled, and RGB tri-color LEDs can also be controlled simultaneously. At the same time, it can also achieve excellent anti-electromagnetic interference performance. Built-in oscillating circuit can reduce external components. PWM control clock is generated by newly developed clock oscillating circuit. It is used in combination with voltage regulator for internal logic power supply. Packaging also greatly contributes to the miniaturization of mounting substrates. In the realization of rich color performance can also effectively reduce the number of peripheral circuit devices and reduce costs.

The future LED lighting is not only capable of achieving richer dimming and color adjustment, but also needs to be more intelligent. In this regard, ROHM is also actively deploying, integrating ROHM's own excellent wireless communication technology, and designing multiple solutions, such as Remote dimming control schemes for batteries, etc., also have related schemes in vehicle-mounted LED drivers.
Wireless power supply
ROHM is aimed at smartphones and mobile devices. The development of the wireless power data transmission and reception control IC "BD57021MWV (Tx) / BD57031MWV (Rx)" is planned to be designed based on the WPC Medium Power (below 15W) standard. Combined with a universal microcontroller to form a transmitter that meets the Qi standard (BD57021MWV); 2) Built-in power supply 10W linear charger (BD57031MWV); 3) Compatible with Low Power (below 5W) product BD57011GWL system Compared with previous products, the calorific value is lower and the thermal design is easier. The BD57011GWL sample was shipped in November 2013, and mass production began in February 2014.

At the Hi-Tech Fair, we fully felt the strength of the comprehensive semiconductor manufacturer ROHM. The world's smallest semiconductors and resistors at the ROHM booth also attracted a lot of attention, including the world's smallest components that exceed the miniaturization limit, and Schottky in development Barrier diode (0.4mm & TImes; 0.2mm), chip resistor (0.3mm * 0.15mm) (new product). It is reported that these miniaturized products use a new process that is completely different from the traditional one, and the dimensional accuracy reaches an amazing ± 10μm. In the future, ROHM will further miniaturize with an original process to achieve a higher-precision appearance size.
Although ROHM is dominated by passive components, active components have been laid out in recent years in order to achieve diversified development and expand more electronic fields. Acquired OKI SEMICONDUCTOR Co., Ltd. (later renamed LAPIS Semiconductor) in 2008, acquired the world's top MEMS acceleration sensor developer Kionix, Inc., and SiC wafer supplier SiCrystal in 2009; acquired Maruzen Electric Corporation in 10 years We look forward to driving passive components with active components and integrating and synergistic development.
