Ball Characteristics

1. BALL NUMBER: Package ball numbers associated with each signals.

2. PIN NAME: The name of the package pin.

Note: The table does not take into account subsystem terminal multiplexing options.

3. SIGNAL NAME: The signal name for that pin in the mode being used.

4. MODE: Multiplexing mode number.

(a) Mode 0 is the primary mode; this means that when mode 0 is set, the function mapped on the

terminal corresponds to the name of the terminal. There is always a function mapped on the

primary mode. Notice that primary mode is not necessarily the default mode.

Note: The default mode is the mode at the release of the reset; also see the RESET REL. MODE

column.

(b) Modes 1 to 7 are possible modes for alternate functions. On each terminal, some modes are

effectively used for alternate functions, while some modes are not used and do not correspond to a

functional configuration.

5. TYPE: Signal direction

–

I = Input

–

O = Output

–

IO = Input and Output

–

D = Open drain

–

DS = Differential

–

A = Analog

–

PWR = Power

–

GND = Ground

Note: In the safe_mode, the buffer is configured in high-impedance.

6. BALL RESET STATE: State of the terminal while the active low PWRONRSTn terminal is low.

–

0: The buffer drives VOL (pulldown or pullup resistor not activated)

0(PD): The buffer drives VOL with an active pulldown resistor

–

1: The buffer drives VOH (pulldown or pullup resistor not activated)

1(PU): The buffer drives VOH with an active pullup resistor

–

Z or OFF: High-impedance

–

L: High-impedance with an active pulldown resistor

–

H : High-impedance with an active pullup resistor

7. BALL RESET REL. STATE: State of the terminal after the active low PWRONRSTn terminal

transitions from low to high.

–

0: The buffer drives VOL (pulldown or pullup resistor not activated)

0(PD): The buffer drives VOL with an active pulldown resistor

–

1: The buffer drives VOH (pulldown or pullup resistor not activated)

1(PU): The buffer drives VOH with an active pullup resistor

–

Z or OFF: High-impedance.

–

L: High-impedance with an active pulldown resistor

–

H : High-impedance with an active pullup resistor

8. RESET REL. MODE: The mode is automatically configured after the active low PWRONRSTn terminal

transitions from low to high.

9. POWER: The voltage supply that powers the terminal’s IO buffers.

10. HYS: Indicates if the input buffer is with hysteresis.

11. BUFFER STRENGTH: Drive strength of the associated output buffer.

12. PULLUP OR PULLDOWN TYPE: Denotes the presence of an internal pullup or pulldown resistor.

Pullup and pulldown resistors can be enabled or disabled via software.

13. IO CELL: IO cell information.
