Notes: 1. Signal names are based on configured functionality. Most connections supply a single signal. Some connections provide a
signal with dual functionality, such as the MODx/IRQx pins that select an operating mode after RESET is deasserted, but act as
interrupt lines during operation. Some signals have configurable polarity; these names are shown with and without overbars,
such as HAS/HAS. Some connections have two or more configurable functions; names assigned to these connections indicate
the function for a specific configuration. For example, connection N2 is data line H7 in non-multiplexed bus mode, data/address
line HAD7 in multiplexed bus mode, or GPIO line PB7 when the GPIO function is enabled for this pin. Unlike the TQFP
package, most of the GND pins are connected internally in the center of the connection array and act as heat sink for the chip.
Therefore, except for GND and GND that support the PLL, other GND signals do not support individual subsystems in the
P
P1
chip.
2. NC stands for Not Connected. The following pin groups are shorted to each other:
— pins A2, B1, and B2
— pins A15, B15, B16, C14, C15, C16, and D14
— pins N3, R1, R2, and T2
— pins N16, P13, P15, R15, R16, and T15
Do not connect any line, component, trace, or via to these pins.
