这芯片怎么涨那么多啊 这芯片怎么涨那么多啊
这芯片怎么涨那么多啊 这芯片怎么涨那么多啊 这芯片怎么涨那么多啊 好贵啊,, 这芯片怎么涨那么多啊 这芯片怎么涨那么多啊?
怎么没人回答呀 这芯片怎么涨那么多啊 这芯片怎么涨那么多啊 说好的3美金呢?呜呜....骗纸!!!!!!! 这售价估计是弄进来有些麻烦步骤吧
但这也导致如果不是要那个加解密的部分,不如直接用h743,浪费掉那些资源也划算。 2.69美金的STM32H750呢 芯片怎么涨那么多啊. 2.69的 应该是 F750吧。 这应该是个人提供的价格,不是通用正常价格,比ST官网还贵了。 这芯片怎么涨那么多啊 我买过几片这货,经过测试,发现里面的FLASH也是2MB的,跟H743是一样的,不排除是个别现象。 好贵呀,买不起 zengyi703 发表于 2019-1-3 11:03

可能现在出货少,后面出货大了说不定就变了。 价格是有点贵 ,,可能现在出货量不大吧 这个片子真的好贵,没用过这高端货! 之前淘宝ST旗舰店买的27.9元
{:titter:}能找到替代的就做好备用方案,一旦涨价,滚粗,,,,{:titter:} F730好用,可惜只有64k内存,lwip+fat就超了 大伙比较关心价格的问题,在这统一回复一下,主要是代理商的库存不是很多,我们洽谈进货的价格偏高,所以出现比大伙预期高的售价,我们能做到就是保证下一批进货时代理商下调价格的情况下会第一时间减价。 Dom 发表于 2019-1-3 21:37

这个片子这么火,你们从原厂拿一批货又如何 momo_li 发表于 2019-1-3 21:56

这货性能很强悍(在MCU角度),而且好像因为加解密性能有加速,是限制出口的,您上digikey,mouser等,非美国本土一律不卖,原厂也不给普通贸易商的,只给代理。工厂要拿货,也得在代理处签上一堆协议,违反了就得处罚(类似中兴)。 这个价格很感人,完全没有玩的冲动 本帖最后由 amigenius 于 2019-1-3 22:55 编辑

那个价格是样品推广价,一个ID只能买几片,H750在他们店,就开卖过2次,都是秒杀,之后一直长期没货。这货弄进来China很麻烦,指望做批量的话,估计得等美帝放开出口限制才有戏。在芯的价格一向很实惠,1K的量这是小批量的小批量,能做这个价已经不错了。
而且我估计ST本身就不想这货大卖,所以故意控制量。估计他们做这货目的就是怼NXP,您看,我H750的Flash少了也能卖您RT1052的价,于是显得743,753的Flash好像很值钱,卖得贵不是坑人的 ST不愿出H750,估计是担心和自家的H743冲突,毕竟一个743的价是两三个750呢。 正在犹豫是H750还是RT1050 zengyi703 发表于 2019-1-3 11:03

以前f103c8遇到后缀CHN,MYS,KOR,是不一样的,只有CHN的才可以用 嘉立创的价格便宜蛮多 {:lol:}{:lol:}{:lol:}确实涨了不少 这芯片怎么涨那么多啊
