On April 23, 2024, semiconductor of law of Chinese – meaning rolled out ST4E1240 RS-485 to send and receive implement chip. New product has compatible output of the transmission speed of 40Mbit/s and PROFIBUS, and twinkling changes and heat is inserted unplug protective function.

 

ST4E1240 is new series of meaning law semiconductor is sent and receive implement first product of chip, for modern high-powered industry application offers powerful and reliable RS-485 signal to transmit a solution. New send and receive implement the RS-485 standard with data rate original outclass of support, can lengthen cable length to realize join many a little bit, total on-line is sent and receive implement the amount can exceed 64. The typical utility of new product includes but controller of process designing logic (infrastructure of equipment of driver of control of building of PLC) , robot, telegraphic infrastructure, intelligence, servo, fiber-optic network, electrified wire netting, data collects a system (include intelligence ammeter) with backboard bus line.

 

The protective function of the buy inside ST4E1240 accords with IEC 61000-4-2 standard, osculatory discharge compression is as high as + / – 12kV, need not join in applying actually exterior ESD protects parts of an apparatus. Still have be as high as + / – the class A of 4kV is fast twinkling changes protective function, accord with the regulation of IEC 61000-4-4 standard, assure data integrality and bus line stability. Heat is inserted unplug circuit can prevent to be in electrify of parts of an apparatus or during inserting redundant condition appears on bus line, can release the parasitism capacitance that is as high as 100pF. In addition, fail-safe protects a function to be able to pull high output n, avoid to detecting inaccuracy appears to decide position when open circuit, short circuit or free bus line. Other function includes protection of 250mA short circuit and heat to close.

 

ST4E1240 satisfies all regulations of TIA/EIA-485 (RS-485) standard, ensure below 5V power source output differs 2.1V of minute of voltage prep above, with compatible and current standard of very hot PROFIBUS spot bus line. In addition, can pass exterior make can bring what the foot dominates chip to close mode, reduce static electric current to 3.5 μ A the following, make its apply to the applied setting that pays close attention to power comsumption.

 

ST4E1240 RS-485 is sent and receive implement care about law semiconductor 10 years to ensure a plan for a long time for goods inside directory, now already put into production, use SO-8 4.9mm X 3.91mm to enclose. ST EStore of store of electron of meaning law semiconductor offers free print.

 

About meaning law semiconductor

The person that meaning law semiconductor has the author of technology of 50 thousand semiconductor and innovation, master semiconductor to supply catenary and advanced production equipment. Regard a semiconductor as perpendicular and integrated manufacturer (IDM) , meaning law semiconductor and two clients, by tens of thousands renown product of a research and development mixes the partner solution, common form builds ecosystem, help them answer all sorts of challenges and new opportunity better, the higher demand that contented world expands to can lasting. A travel that the technology of meaning law semiconductor allows people more intelligence, make power source and energy management more efficient, connective letting the cloud turns equipment application independently more extensive. Acceptance of meaning law semiconductor will be counteracted at realizing carbon 2027 (in limits 1 and 2 inside complete implementation carbon is counteracted, in limits 3 interior divide implementation carbon to counteract) .
