Domestic hart chips to replace international manufacturers' products
Since its establishment in 2003, Microcyber has devoted itself to the technological breakthroughs and development of Industrial Internet of Things, and has made continuous progress in the field of industrial communication technology.
The company's HART modem chip HT1200M, Profibus DP communication chip APC3 and Profibus PA bus communication chip and other fieldbus communication chip products in the field of industrial control have successfully broken the monopoly of the international communication chip manufacturers such as TI, ADI and MaxicoM, and realized the design of domestic substitution for the fieldbus communication chip, especially the HART chip.
In the future, with the development of China's Industry 4.0 and the acceleration of domestic substitution, the company will continue to layout and develop in the industrial control field, such as temperature transmitters, pressure transmitters, liquid level transmitters and other applications. On the market side, as the industrial control market is less affected by changes in the consumer environment, and there are more and more domestic enterprises choose to use the domestic industrial control chip, with the use of these chips, Microcyber also launched and the chip to match the development of the development board and development materials.
HT1200M HART Fieldbus Modem is a low-power modem chip that can be used in HART devices, which only needs a small number of external components to complete the modulation and demodulation of HART signals.The HT1200M HART Fieldbus Modem is compatible with the SYM20C15 and HT20C15 and with ON OnSemi's A5191HRT and HT2015.
HT1200M HART Fieldbus Modem：
1. Single chip, FSK modem (Semi-duplex 1200b/s)
2. Integrated receiving the circuit of band-pass filter and transmitting signal waveform shaping
3. External 460.8kHz crystal or ceramic filter
4. Working temperature: -40℃～85℃
5. Working current: ＜140uA(3.3V）
6. LQFP32 and PLCC28 package
