Pin Specifications
The K210 uses a well-designed pin layout to ensure that the signals are on the
BGA outer ring to allow PCB designers to fanout and route easily, improve electri-
cal performance and reduce design difficulty.
Since the K210 contains multiple IO signals from the power domain and differ-
ent power domains may have different voltages, the following will list the power
domains used:
Power Group Power Domain VoltageV Connected to Name
A 0 3.3/1.8 Other domains in group VDDIO0A
A 1 3.3/1.8 Other domains in group VDDIO1A
A 2 3.3/1.8 Other domains in group VDDIO2A
B 3 3.3/1.8 Other domains in group VDDIO3B
B 4 3.3/1.8 Other domains in group VDDIO4B
B 5 3.3/1.8 Other domains in group VDDIO5B
C 6 3.3/1.8 Other domains in group VDDIO6C
C 7 3.3/1.8 Other domains in group VDDIO7C
LV IO LV IO 1.8 Independent VDDIO18
