200MHz ARM7 MCU

Hi&nbsp;All,<br />&nbsp;&nbsp;&nbsp;&nbsp;I'm&nbsp;going&nbsp;to&nbsp;design&nbsp;a&nbsp;200MHz&nbsp;ARM7&nbsp;MCU&nbsp;with&nbsp;Flash&nbsp;embedded.&nbsp;Any&nbsp;market&nbsp;demand&nbsp;on&nbsp;this&nbsp;product.&nbsp;Or&nbsp;what&nbsp;feature&nbsp;you&nbsp;want&nbsp;to&nbsp;see&nbsp;on&nbsp;this&nbsp;MCU?

  

  

  

200MHz&nbsp;is&nbsp;ARM&nbsp;core.&nbsp;Internal&nbsp;bus&nbsp;could&nbsp;under&nbsp;133MHz&nbsp;or&nbsp;ratio&nbsp;of&nbsp;200MHz.<br />Do&nbsp;you&nbsp;need&nbsp;external&nbsp;SDRAM&nbsp;or&nbsp;just&nbsp;embedded&nbsp;another&nbsp;SRAM&nbsp;?<br />If&nbsp;embedded&nbsp;SRAM&nbsp;,&nbsp;how&nbsp;about&nbsp;its&nbsp;size&nbsp;?

  

ARM7EJ-S?

  

  

  

Why&nbsp;you&nbsp;regard&nbsp;ARM7-EJS&nbsp;200MHz&nbsp;is&nbsp;not&nbsp;a&nbsp;good&nbsp;idea&nbsp;?<br />Can&nbsp;you&nbsp;give&nbsp;me&nbsp;more&nbsp;input&nbsp;?

SRAM多大呢？究竟多大呢？要啥外围功能呢？ARM7跑这么快，多少有点意义吧？谁来说说

不知楼主是不是想搞一个类似的东西出来？

Anyway&nbsp;I&nbsp;think&nbsp;this&nbsp;chip&nbsp;should&nbsp;include&nbsp;a&nbsp;highspeed&nbsp;sram.&nbsp;
