Company have a project need to make it one hundred percent localization, we conducted two months from October to December of the localization of research, checked among countless domestic manufacturer's website, in contact with the many domestic manufacturers agents, ask for too many device information, now finally about to end, it is the home to do more and more of the IC, but doing less prominent, as long as the index to a slightly higher, the room of optional is small, now on the two months of work for a summary, hope can give other need localization engineers a reference,
Interface chip, level conversion chip recommended actis semiconductor, affordable variety complete,
DC - DC high current recommended mornsun, can achieve 16 a, small current recommended jia tai, can replace the in situ with TI,
"In fact, many domestic manufacturers can do, but can do 200 mv low large current of 3 a little, here are two recommended, core micro friends and bearing core technology, core friends micro performance almost, affordable, bearing the core technology performance is good, but the price is expensive, a piece of around four hundred,
Logic gate, recommend wuxi micro love core electrons, affordable, complete category,
Double data rate 2) 1-gigabit memory chips is recommended, honestly choose xi 'an purple light, the core
Gigabit protocol conversion chip selection, only the zte and yu too car can do, and are Rgmii, does not support Sgmii,
Nand flash recommend Beijing mega innovation, variety complete
Nor flash less parallel interface of domestic manufacturers, recommend Taiwan flourishing macro electronic
Eeprom recommended poly (semiconductor, as if the manufacturer also is not much,
As for the diode, triode these recommended leshan radio, low prices, variety complete,
Highlight, distribution of the clock chip (clock buffer) manufacturer is less, only the two sides of a room, also sell dead you, a piece of more than two thousand, then he finally found another ningbo science and technology, more affordable, suzhou micro - core has actually, but more expensive,
FT series DSP recommended national defense science and technology university six homes, basic on the TI,
K7 series FPGA recommend fudan microelectronics, with more people, performance, or can do 325 t,
Spartan series FPGA recommend high clouds, information, service good,
AD/da recommended core hundred micro, AD can do 12 bit 500 m sampling rate, da can do 16, 1 g refresh rate,
As for those who have CLP xx, xx factory, I will not recommend, your touch,
Through the localization of research, personal feel domestic manufacturers more and more cow force, in the field of continuous breakthrough the limit, hopes to make persistent efforts, domestic manufacturers of chip performance better, more complete information, more convenient site,
Phone code word is really not easy

CodePudding user response:

More than two thousand clock chip, can't afford to use

CodePudding user response:

Have to make a test, performance and compare?

CodePudding user response:

reference 1st floor wocaonimalegebi response:

two thousand clock chip, can't afford to use.

Ora cheaper, more than eighty will be enough

CodePudding user response:

refer to the second floor worldy response:

have do a test, a performance comparison?

Not yet, reference manual, the next step to prepare for design,

CodePudding user response:

Why do you see Taiwan chip?

CodePudding user response:

reference 5 floor bsnow reply:

why did you see Taiwan chip meh?

Try to choose in mainland, the macro is Taiwan's flourishing,
