We using commercial device CY7c4122KV13, we design the board with 1.2V for VDDQ (we work with data sheet rev 'M' )

In new data sheet rev 'Q'  changed the voltage VDDQ to 1.1 for commercial devices.

The question is : can we continue works with 1.2V for VDDQ or we must change to 1.1V?

Hi,

 

Several I/O signaling standards are supported by the QDR-IV, which are programmable by the user. They are:

■ 1.2 V and 1.25 V HSTL/SSTL

■ 1.1 V and 1.2 V POD (Pseudo open drain)

So for all the cases you can use 1.2 V VDDQ for Industrial grade device and only 1.1 V VDDQ for Commercial grade device.

 

Thanks,

Pradipta.
