This section describes the Unused/Reserved balls connection requirements.
NOTE
The following balls are reserved: A27 / Y5 / Y10 / AA1 / AA2 / AB1 / AB2 / AC1 / AC2 / 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 4.3, Signal Descriptions.
Balls | Connection Requirements |
---|---|
AE15 / AC15 / AE14 / D20 / AD17 / AC17 / AC16 / AB16 / V27 / AH25 / AE27 / AD27 / Y28 / G28 / H27 / K27 / M28 | These balls must be connected to GND through an external pull resistor if unused |
V28 / F18 / E20 / E23 / D21 / C20 / C21 / AG25 / AE28 / AD28 / Y27 / G27 / H28 / K28 / M27 / F17 / C25 | These balls must be connected to the corresponding power supply through an external pull resistor 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) |
K14 (vpp) | This ball must be left unconnected if unused. |
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 Pad Configuration Register can be left unconnected.
