Signal Description
Analog Ground.
Ground return for analog supply (AVCC). all grounds can
be tied together using a single ground plane.
Digital Power Supply - Core.
+2.5 V supply for core digital circuits.
Digital Power Supply - I/O Ring.
+2.5/3.3 V supply for digital I/O circuits. The digital input
circuits running off of this rail, having a TTL-level threshold
and over-voltage protection, may be interfaced with 3.3/5.0
V, when the IO supply is 3.3 V, and 2.5/3.3/5.0 V when 2.5
V.
Digital Ground.
Ground return for core digital supplies (VCCD). All ground
pins can be tied together using a single ground plane.
Substrate Ground.
Ground for chip substrate. All ground pins can be tied
together using a single ground plane.
No Connection.
