FRAME ENGINE AND DATA LINK MANAGER 32P672
Notes on Pin Description:
1. All FREEDM-32P672 non-PCI inputs and bi-directionals present minimum
capacitive loading and are 5 Volt tolerant. PCI signals conform to the 3.3 Volt
signaling environment.
2. All FREEDM-32P672 non-PCI outputs and bi-directionals have 4 mA drive
capability, except the PCICLKO, RBCLK, TBCLK and RBD outputs which
have 8 mA drive capability.
3. All FREEDM-32P672 outputs can be tristated under control of the IEEE
P1149.1 test access port, even those which do not tristate under normal
operation. All non-PCI outputs and bi-directionals are 5 V tolerant when
tristated.
4. All non-PCI inputs are Schmitt triggered. Inputs TMS, TDI and TRSTB have
internal pull-up resistors.
5. Power to the VDD3V3 pins should be applied before power to the VDD2V5
pins is applied. Similarly, power to the VDD2V5 pins should be removed
before power to the VDD3V3 pins is removed.
