Pad compatibility

This section describes the pads which demand particular attention when either an

SPC560Px/SPC56EL60 compatible application or a compatible board is developed.

Pads which are not covered in this section are fully compatible. For a detailed description of

all SPC560Px/SPC56EL60 pads refer to Appendix A: Detailed pad list.

Even if oscillator pads and reset pads are considered compatible, additional information on

these pads is provided Section 2.4: Oscillator pads and Section 2.5: Reset pad.

2.1

Upward compatible pads

If an SPC56EL60 pad has all the functionalities of an SPC560Px pad plus additional ones, it

is an upward compatible pad.

Table 1 shows the list of all the upward compatible pads.

2.2

Partially compatible pads

There are two types of partially compatible pads, according to the supported functionalities:

●

Some but not all SPC560Px functions are supported on SPC56EL60 (refer to Table 2)

●

Some but not all SPC56EL60 functions are supported on SPC560Px(a) (refer to

Table 3)

Table 2 and Table 3 show these pads and indicate other pads which offer compatibility on

the same function.

Users of these devices must carefully choose the functionality of each of these pads to

obtain a fully SPC560Px/SPC56EL60 compatible application board.

Table 1.

List of the SPC560Px upward compatible pads(1)

A full description of all these pads can be found in Appendix A: Detailed pad list.
