ST = Schmitt Trigger (Hysteresis), TS = Three-State. Signals ending with “-” are active low.
NOTE:
2. Pin 39 (V
CC
_CORE3 in 3841), has been reassigned as LFXTALI. For 3841 compatibility, it may be tied to V
CC
.
Pin 62 (TRST- in 3841) has been reassigned as MLBE. For 3841 compatibility, it may be tied low through 1K.
Pin 105 (V
CC
_IO5 in 3841) has been reassigned as USB ATTACHED. For 3841 compatibility, it may be tied to V
CC
.
Output pins typically drive to positive voltage rail less 0.1V. Hence with a supply of 2.7V the output will just meet 5V TTL signal levels at
rated loads.
