主题：【求助】河里有没有人做芯片的呢？ -- 忧心

现在在欧洲这边有个项目，可放入首饰中的微型录音芯片，希望在国内找到设计生产厂家，具体要求如下：

A microboard with a micro controller capable to do the following:

- record audio at 22kz

- silence detect

- timestamp via real clock

- work in fifo mode or fill up memory and stop.

- the board should be small enought to be hidden with a micro battery in a jewel

- to download data a simple fixed rate serial line could do.

- battery reload circuitry could be external

河里如果有朋友做类似的项目，可以私信给我联系，谢谢。
