你好,

客户在调试CY8CMBR3108的时候,需要使用到低功耗,目前扫描间隔为120ms,实际测试发现在最后一次松开按键后的约350ms内(图片上的AB间隔),功耗仍然比较大,过了350ms后功耗才完全的降下来,这个时间是固定的吗,还是说是可以调整的呢,tks !图片.jpg

1: 你给的示波器测试的电压图我没看明白你想表达什么,但是MBR3的低功耗设计见解释2.

2:请在 http://www.cypress.com/?rID=90800 下载 CY8CMBR3xxx CapSense Design Guide 并仔细阅读第 7 章 Low Power Design.

The CY8CMBR3xxx controller supports five operational modes:
1. Active Mode
2. Look-for-Touch Mode
3. Look-for-Proximity Mode
4. Deep Sleep Mode
5. Configuration Mode

具体的操作图见figure7-1。
