IIC-Taiwan / CeraMicro announces eZigBee module with SiP technology
Optimistic about the diversified application opportunities of ZigBee, CeraMicro Technology (CeraMicro Technology) in the "2008 International Integrated Circuit Seminar and Exhibition" (IIC-Taiwan 2008) announced the chip-level packaging eZigBee solution. The new eZigBee module is integrated with SiP packaging technology, which can reduce the size of the module to 7mmx7mm, which brings customers the advantage of greatly reducing costs.
Zeng Minghuang, general manager of Porcelain Micro Technology, said that the current ZigBee has been widely used in home automation, industrial applications and medical industries, and its price has continued to decrease; however, the development of related solutions is quite complicated. Especially for service providers, when facing ZigBee system integration, they must also consider wireless system design, low-level software, chip processing, RF and PA selection, and overall system issues, etc. until the actual implementation is resolved When planning, the cost of investment often exceeds expectations.
In view of this, Porcelain Micro Technology has launched a competitive eZigBee solution. This fully functional RF module can effectively solve the problem of software and chip system compatibility, so that manufacturers no longer need to consider wireless design, software and chip system compatibility issues. The size of the eZigBee module is only 7mmx7mm, and the manufacturer can directly use it as a construction module of the ZigBee system to quickly and easily construct the WSN system to obtain a faster time to market, thereby reducing system costs.
eZigBee products can be divided into four categories, which can be given great flexibility of hardware according to different application needs of customers. The CZiP01 (CZ2410) system-on-a-chip is a transceiver module that integrates 8051 MCU, 16KB RAM and 128KB flash memory, and is compatible with 2.4GHz IEEE802.15.4. It is hardened for low power consumption and minimum processor cost. Body MAC accelerator and AES encryption.
The CF 2206 and CF 2268 RF front-end modules integrate high-efficiency and linear power amplifiers, RF switches, LNA and BPF, etc., greatly reducing board space and external components, and can be used as the best application for 2.4GHz ISM band to enhance output power. The device uses a 4.5mm x 4.5mm package design.
Zeng Minghuang said: "eZigBee is an application of embedded system as its name implies. And because ZigBee's application is mainly in some traditional industries, such as lighting manufacturers, curtains or window manufacturers, they often encounter some challenges in innovative applications. The eZigBee solution The reduction in RF, volume, and technology thresholds allows manufacturers to match sensors with their applications to achieve a complete product design, helping to reduce investment costs and increase benefits for these industry players. "
Therefore, Zeng Minghuang said that he is quite optimistic about ZigBee in the field of RF applications, which will help drive the innovation and development of traditional industries. "We started with modularization and designed a small and fully functional RF module solution, and the rest is left to customers for a variety of innovative applications, which will be the driving force behind the application of ZigBee in this field." In addition, the company will also release a complete software development kit (SDK) by the end of this year.
Reverse Conducting Thyristor(RCT)
Reverse Conducting Thyristor(RCT) is also called Reverse- appreciation Thyristor.The characteristic is that a diode is connected in reverse parallel between the anode and cathode of thyristor, so that the transmitting junction of anode and cathode is short-circuited.As a result of this special circuit structure, it has high voltage resistance, high temperature resistance, short turn-off time, low switching voltage and other good performance.For example, the turn-off time of the reverse thyristor is only a few microseconds, and the working frequency is dozens of KHZ, which is better than the fast thyristor (FSCR).This device is suitable for switching power supply and UPS uninterrupted power supply. One RCT can replace one thyristor and one continuous current diode respectively.
