Note: For proper operation of programming recovery mode, if a V
DD
supply brown-out occurs
during programming, a minimum supply ramp down time for only the V
DD
supply is recommended
to be 10 ms or longer by using a programmable regulator or on-board capacitors.
4.2.2.2 Hot Sockeng
The following table lists the hot socketing DC characteristics over recommended operating
conditions.

1. Assumes device is powered-down, all supplies are grounded, AC-coupled interface, and input pin
pairs are driven by a CML driver at the maximum amplitude (1V pk–pk) that is toggling at any
rate with PRBS7 data.
2. Each P and N transceiver input has less than the specied maximum input current.
3. Each P and N transceiver output is connected to a 40Ω resistor (50Ω CML termination—20%
tolerance) to the maximum allowed output voltage (V
DDAmax
+ 0.3V = 1.4V) through an AC-
coupling capacitor with all PolarFire device supplies grounded. This shows the current for a
worst-case DC-coupled interface. As an AC-coupled interface, the output signal will settle at
ground and no hot socket current will be seen.

Note: The following dedicated pins do not support hot socketing: TMS, TDI, TRSTB, and DEVRST_N.
Weak pull-up (as specied in GPIO) is always enabled.
4.3 Input and Output
The following section describes DC I/O levels, dierential and complementary dierential DC I/O
levels, HSIO and GPIO on-die termination specications, and LVDS specications.
