LAPIS Semiconductor announced on September 17, 2013 that it has developed an 8-bit microcontroller (MCU) "ML610Q111/ML610Q112" for LED lighting control. According to reports, the new product is equipped with a 6-channel PWM (Pulse Width Modulation) port, which can achieve a variety of hue and brightness, and can get rich lighting effects intimately matched with life scenes and interiors.
The PWM resolution of the new product is 16bit (can work at 16.384MHz), and the PWM control clock is generated by the newly developed clock oscillation circuit. The oscillation frequency is 8.192MHz±1% (at 25°C. -10～85) ±2% at °C and ±2.5% at -40°C to 85°C). According to the introduction, when the oscillation circuit is used in combination with the built-in logic power supply voltage regulator, the number of external components such as capacitors for logic power supply can be reduced, and the lighting device and the lighting device can be reduced by using a small package. The package substrate size contributes.
The new product's built-in comparator can monitor changes in the external environment such as sudden voltage fluctuations, so it can immediately take countermeasures to help the product work stably. The CPU is an 8-bit RISC core developed by LAPIS. The improved noise resistance is ensured by the improved circuit and layout, and the withstandable air discharge exceeds the IEC61000-4-2 Class 4 standard (±15kV) and reaches the measurement limit of ±30kv. The power supply voltage is 2.7 to 5.5V.
In the ML610Q111 and ML610Q112, the ML610Q112 is a high-end product. The memory capacity of the ML610Q111 is 24KB for flash memory and 2KB for SRAM, and 32KB and 4KB for ML610Q112. In addition, the AD converters are equipped with 10bit successive approximation products, but the ML610Q111 is a 6-channel type, while the ML610Q112 is an 8-channel type. The package used is different. The ML610Q111 is available in a 20-pin TSSOP (6.5mm x 4.4mm) package and the ML610Q112 is available in a 32-pin LQFP (7.0mm x 7.0mm) package.
Samples have been available for both products. The sample price for the ML610Q111 is 150 yen (excluding the reference price for tax), and the sample price for the ML610Q112 is 200 yen (excluding the reference price for tax). Production is scheduled to begin in December 2013. In addition to the IC, there is also a reference board and software development environment that can be easily evaluated. Moreover, after registering on the LAPIS homepage, users can also use a variety of manuals and tools.
In addition, the new product will be on display at the ROHM exhibition area of ​​"CEATEC JAPAN 2013" held at the Messe Convention Center in Chiba, October 1st - 5th, 2013.
The shipboard medium voltage VFD power cables are suitable to each kind of river sea ships and the sea petroleum to each kind of river sea ships and the sea petroleum platform and so on in the aquatic construction and loses the distribution line to the shielding properties request strict power circuit, especially is suitable in the frequency conversion control transmission system makes the power supply or tie the cable.
Shipboard VFD Power Cables are: XLPE insulated flame retardant shipboard medium voltage VFD power cables, XLPE insulated flame retardant shipboard low voltage VFD power cables and XLPE insulated fire retardant shipboard low voltage VFD power cables.
