SP605 - Does the SP605 support 1.8V I/O banks?

Description

Can the SP605 Evaluation Kitsupport a1.8V bank voltage? What bank voltages are available on the SP605?

Solution

The bank (VCCO) voltages for all banks in SP605 are fixed and do not support 1.8V.The XC6SLX45T device on the SP605 has 4 banks, and the VCCO voltage for each of these banks is as follows:

Bank 0 2.5V (VCCO0)
Bank 1 2.5V (VCCO1)
Bank 2 2.5V (VCCO2)
Bank 3 1.5V (VCCO3)

Other voltages on the SP605 include:

VCCINT 1.2V
VCCAUX 2.5V

There is a linear regulator on the SP605 (U44), which provides a 1.8V voltage to the Linear Flash Memory on the board. This cannot be used as a bank voltage.
