Second, TCC730/TCC731 series of Telechips
Producing area: South Korea
1,TCC730/TCC731 series
According to function, performance, tone quality different fields, Telechips TCC730/731 is really a little better than the chip of STMP3410 of Sigmatel,etc., the bass sense is sufficient, every frequency band displays and relatively equilibrates, and the sound field is wider; But compared with Philip SAA7750/7751 there is certain disparity. In addition, Telechips TCC730 price is a bit cheaper than SAA7750, but need outer ROM, there are many peripheral components, so it is rare to adopt MP3 products of this kind of chip and have products with exquisite stature to emerge.
The industry generally think Telechips chip different fields behave and is between Sigmatel STMP3410 and SAA7750/7751 series. Adopt MP3 of this chip on the basis of one’s own tone quality, if also there is certain promotion after allocating the more top-grade earphone. Machine general emblem of type this mix sea full of trees fill MX300 ‘ Or OEM sea full of trees fills in) The earphone, this earphone belongs to the sea full of trees to fill in the most popular earphone in the series of popular MX, so propose that can try the sea full of trees to Electronic Manufacturing| Electronic Manufacturing Services| China Electronic Manufacturer| Electronics Manufacturer| Electronics Manufacturing China| China Electronics Manufacturers| fill to the friend with higher requirement of the tone quality in MX500, or KOSS SP/KOSS PP a bit more top-grade, fills in PX100/PX200 in the sea full of trees. Because MP3 which adopts this chip had certain potentiality on the tone quality, did not tell you like all distributors, all MP3 tone quality have, promote behind changing top-grade earphone, in fact some MP3 one’s own chips and designing, the restriction of the production technology makes it not have excavating the space of tone quality.
2,TCC767/TCC766/TCC760
TCC760 decodes the chip, 32 ARM940Ts with power simplify the order and collect the processor core, up to 140MHz (Philip PNX0102 decode whom chip adopt 60MHz ARM7 processor core frequently mainly, most common Sigmatel 3520 chips are mainly 75MHz frequently) ,Have allocated 64Mbit SDRAM memory of the large capacity.
TCC767 and TCC766 all adopt FPBGA to encapsulate, the pin is different in figure, the main difference lies in 766 built-in audio frequency Codec chip, and 767 Codec chip needing to put outside works in coordination, for example this fund V10 adopts U.S.A. TI (the instrument of Dezhou) AIC23B has his strong points voice Smt Electronic Manufacturing| Electronics Contract Manufacturing| Electronic Contract Manufacturing Services| Subcontract Pcb Assembly frequently Codec chip, tone quality result. The biggest difference between TCC767, TCC766 and series of preceding 76x is built-in USB2.0 interface controller at a high speed, adopt NOR Flash (other series are mostly 512KB NOR Flash) of 1MB .
