This section describes the connection requirements of the unused and reserved balls.
NOTE
The following balls are reserved: A27, Y5, Y10, B28
These balls must be left unconnected.
NOTE
All unused power supply balls must be supplied with the voltages specified in the Section 5.4, Recommended Operating Conditions, unless alternative tie-off options are included in Section 4.4, Signal Descriptions.
BALLS | CONNECTION REQUIREMENTS |
---|---|
AE15, AC15, AE14, D20, AD17, AC16, V27, AH25, AE27, AD27, Y28 | These balls must be connected to GND through an external pull resistor if unused. |
E20, D21, E23, C20, C21, V28, F18, AG25, AE28, AD28, Y27, F17, C25 | These balls must be connected to the corresponding power supply through an external pull resistor if unused. |
K14 (vpp) | This ball must be left unconnected if unused |
AF14 (rtc_iso) | This ball should be connected to the corresponding power supply through an external pull resistor if unused; or can be connected to F22 (porz) when RTC unused (level translation may be needed) |
AB17 (rtc_porz) | This ball should be connected to VSS when RTC is unused; or can be connected to F22 (porz) when RTC unused (level translation may be needed) |
NOTE
All other unused signal balls with a Pad Configuration register can be left unconnected with their internal pullup or pulldown resistor enabled.
NOTE
All other unused signal balls without a Pad Configuration register can be left unconnected.
