| Abstract: | A USB bus based data interface technology for full auto Patch-Clamp system is discussed in the article.The main controller is CY2131QC(Cypress) and the logic controller is EPM3256A(Altera).Optocouplers are used to get rid of the noise from the interface.It makes the installation of the Patch-Clamp system easier by using the USB bus,and is suitable for the new generation of the Patch-Clamp system with a high speed of 1M bytes/s. |
