Industrial wireless technology WIA-PA has been accepted by IEC as an international standard. In order to promote the development of industrialization, it is necessary to develop the WIA-PA core chip and its industrial intelligent equipment. Recently, Shenyang Keaowei Polytron Technologies Inc developed the first domestic WIASoC2400 system on chip shock came.
The WIASoC2400 chip is industrial networking system on chip an integrated 2.4GHz wireless transceiver, the 32 bit ARMCortex-M3 processor, AES128 encryption and decryption module, hardware protocol engine, DMA module, FLASH memory, SRAM memory, timer, synchronous and asynchronous serial port. The WIASoC 2400 chip conforms to the IEEE 802.15.4e standard.
At present, the main application fields of WIASoC2400 chip are smart home, intelligent building, process automation, computer peripherals, wireless meter reading, smart grid and other integrated Internet of things industry, so as to achieve efficient and high-speed control operation.

Relative to other WIASoC2400 chip chip can support WIA, compared to WirelessHART, ISA100.11a a variety of industrial networking standard protocol, design the hardware implementation of the protocol engine, design and implementation of high performance AES DMA module and access control module, and the chip high speed bus connecting the radio frequency module, access to high-speed and reliable, with high integration, low cost and high stable, low power consumption characteristics.
I believe that the advent of the WIASoC2400 chip of Zhongke can make a significant response in the field of science and technology and industrial Internet of things, enabling our chip technology to be put into use in more modules, reducing the largest industrial cost and applying it in more industrial areas. In the future, China and China will continue to develop and occupy highland, continue to create new achievements and create a greater future with our scientific and technological products.
