Hi Team,

1. Can you share IIH,IIL parameters of CY7C65642-48AXCT

2. Whether the VIH,VIL,VOH and VOL parameters are applicable for port indicator pin also (like amber, green)

3. For power consumption calculation, I am using internal LDO so VREG = 3.3V and VCC =5V.

Let consider no.of active downstream port = 2

Max. current = 78.6mA.

For worst case power calculation i have to take Vcc=5V

or Vreg=3.3V

Hi,

1. Unfortunately we dont have those parameters currently available on web.

2. Yes, the VOH and VOL parameters are applicable to the LED pins since they are output pins.

3. For power consumption calculations, please use VDD which is 3.3V.

Best Regards,

Sananya

Hi Saranya,

Could you tell me why we taken 3.3V for power calculation when the system is operated by bus powered configuration?

Whether we have to consider digital I/O operating voltage for that calculation?

Hi,

We take 3.3V because even in bus-powered configuration, the hub is powered by 3.3V (which comes from VREG) and it is the operating voltage as you mentioned.

Best Regards,
