1. All inputs are 5-V friendly. All 5-V outputs are slow slew rate. The QSMCM and TouCAN pins have some slew rate
2. These pins are powered by KAPWR (Keep Alive Power Supply).
3. This pin is an active negate signal and may need an external pull-up resister.
4. Drive strength was 45/90 in make sets prior to K62N.
5. Drive strength was 45/90 in make sets prior to K62N.
The pad ring supports 234 functional pins (284 including all power and ground). Each
pin and the functionality it supports are described in this section. All references to tim-
ing in this document are numbers that are expected for a typical case process with a
50-pF load at 25
V. The 5-V supply is generally referred to as the 5-V supply, and the 3.3-V supply is
referred to as the 3-V supply in this section.
Pin Name: addr_sgpioa[8:31] (24 pins)
Address Bus – Specifies the physical address of the bus transaction. The address is
driven onto the bus and kept valid until a transfer acknowledge is received from the
slave. ADDR8 is the most significant signal for this bus.
