First, wireless SoC (on piece system) core -MCU

We today the time, are the wireless time, uses radio frequency SoC (on piece system) to carry on the wireless communication design, is develops the low cost, the low power loss wireless communication application system ideal plan.

Radio frequency SoC (on piece system) the characteristic is:

1/ special design, the complete high-frequency unit electric circuit completely will integrate in the electric circuit, from the wireless core machine to the antenna between, only had the simple filter circuit piece by piece, the system designer completes does not need to carry on any high-frequency circuit design;

2/ uses the special design, causes between the wireless chip and the microprocessor and the high frequency line, realizes the perfect coordination, the digital circuit decreases to the high frequency communication influence to is smallest;

3/ designs the microprocessor and the wireless chip a body, turns the wireless monolithic integrated circuit, so long as you understand the monolithic integrated circuit, may with ease complete the wireless communication functional design development.

As radio frequency SoC (on piece system) the core - inserting -like microprocessor, needs to be able to carry on in the wireless communication massive software processing, including the error correction, prevents the collision, communication agreement processing and so on, specially in the complex network system and the future short distance, in the micro power loss IEEE 802.15.4 standards, will need the microprocessor to undertake the massive computations and the control function,

In in this microprocessor essence choice, needs to consider that,

1/ fast computation ability;

2/ extremely low power dissipation;

3/ high efficiency development kit,/assembles the /DEBUG tool including the translation;

4/ and high frequency wireless receiving and dispatching partial electric circuits organic synthesis;

5/ application software support;

Wireless SoC (on piece system) the chip development company after the process synthesis consideration above factor, the majority as if by prior agreement choice had many years historical 8,051 microprocessors essence to take wireless SoC (on piece system) the microprocessor;

Regarding prepares general monolithic integrated circuits engineer and electronic engineer which studies the use wireless technology says, this is an excellent news, because, from wired to wireless technical transition in, no longer will need reto study and the familiar monolithic integrated circuit structure/command system/compiler; Moreover, if you choose the Chengdu wireless dragon communication science and technology company the wireless 8,051 monolithic integrated circuits series development kit, you do not need again the familiar development kit, but may directly study the wireless communication the knowledge; Direct fast enters the wireless communication in the practice;

Second, already in market 8,051 essences wireless radio frequency SoC (on piece system)

8,051 compatible wireless monolithic integrated circuits at present the world altogether has 4 kinds, but the mainstream is chipcon Corporation's cc1010, Nordic Corporation's nRF24E1/nRF9E5.

These three kind of wireless monolithic integrated circuits respectively have own characteristic, chipcon Corporation's cc1010 have 32kbyte Flash+2048+128 SRAM, three channels A/D 10 switches, 64 TQFP seal, transmit communication speed 76.8k bit/s, on the piece have: RTC/2UART/2PWM/SPI/26 I/O/DES adds code telegram/看门�?electric circuit and so on, the high-frequency unit completely integrates on the chip, works in 300-1000mhz, smallest power dissipation only 0.2uA; Small amount price about 50 Renminbi/each piece.

Nordic nRF24E1 work in 2.4GHZ, nRF9E5 work in 433MHZ and 868-930MHZ, although the Nordic wireless monolithic integrated circuit memory is smaller, only has 4K, but because uses better power source management way smallest power dissipation only 2.0uA; And uses the fast SHOCKBURST technology, domestically transmits communication speed 100k bit/s in to purchase, small amount price in 40 Renminbi/each piece.

Third, is going to promote 8,051 essences new generation of wireless SoC (on piece system)

This year the second quarter, chipcon Corporation will promote the new generation of work in 2.4Ghz, compatible IEEE 802.15.4 standards high performance 8,051 essences wireless monolithic integrated circuit cc2430, this wireless monolithic integrated circuit main parameter as follows:

1/ MCU uses 8,051 8-bit single cycle essence, comparatively standard 8,051 quick 8 times;

2/128kByte FLASH memory + 8kByte RAM;

3/ RTC/2USART/2PWM/SPI/DES adds code telegram/看门�? electric circuit and so on;

4/ADC electric circuit;

5/ high-frequency unit completely integrates on the chip, works in 2.4Ghz, the low power consumption;

6/ batch (million) price in 4 US dollars/each piece.

The 7/ZigBee wireless node, is coordinated including the network, route, simple pitch point function;

CC2430 uses Chipcon Corporation newest Smart the RF 03 technologies and the 0.18CMOS craft manufacture, 7x7 mm the QLP 48 packing;

Moreover also has many to use 8,051 essences the wireless monolithic integrated circuits to estimate promotes in this year;

Fourth, the wireless Long Xin C51RF-3 development kit will support develops cc2430

If you actual enough to start to begin to develop take radio frequency SoC (on piece system) as the core application system, after you need to provide the wireless monolithic integrated circuit development kit to complete translation work and so on wireless communication procedure downloading/debugging/test;

The Chengdu wireless dragon communication science and technology company (www.c51rf.com) the beginning of the year promotes new generation of C51RF-2 wireless monolithic and the development kit and the series reference design module. You if use the wireless dragon communication science and technology independent intellectual property rights development design the c51rf-2 development system, you only need c51rf-2 to be allowed fast to complete to nRF24e1/nRF9E5/cc1010 and so on three kind of wireless monolithic integrated circuits chips appraisal test/software development/debugging and so on, because the product price is lower than the overseas similar product 60%, moreover works reliably, easy to operate, therefore deeply welcome general monolithic integrated circuits engineer and electronic engineer; The product falls short of demand;

Moreover in order to let the general monolithic integrated circuits amateur and electronic engineer can bear, the wireless dragon communication science and technology company to purchases the c51rf-2 development system in the promotion time individual user and the education system user provides a larger scale preferential benefit and the discount;

At the same time, the wireless dragon communication science and technology company through US'S design development center, unceasingly is tracking newest 8,051 radio frequencies SoC (on piece system) and other wireless chip systems technical progress, unceasingly promotes and unceasingly develops newly, low cost wireless SoC (on piece system) develops the system;

The wireless dragon communication science and technology company at present is developing c51rf-3 and so on the new generation of wireless monolithic integrated circuit development system and the wireless design tool, c51rf-3 in the support at present nRF24e1/nRF9E5/cc1010 and so on in three kind of wireless monolithic foundations, the increase will support cc2430 and so on the new generation of wireless monolithic integrated circuit function.
