Notes:
1. OV
DD
supplies power to the processor bus, JTAG, and all control signals and V
DD
supplies power to the processor core and
the PLL (after filtering to become AVDD). These columns serve as a reference for the nominal voltage supported on a given
signal as selected by the BVSEL pin configuration of Table 4 and the voltage supplied. For actual recommended value of V
IN
or supply voltages see Table 3.
2. These are test signals for factory use only and must be pulled up to OV
DD
for normal machine operation.
3. To allow for future I/O voltage changes, provide the option to connect BVSEL independently to either OV
DD
(selects 3.3V) or
to OGND (selects 1.8V/2.0V).
4. Uses one of 15 existing no
-
connects in PC745’s 255
-
BGA package.
5. Internal pull up on die.
6. Internally tied to GND in the PC745 255
-
BGA package to indicate to the power supply that a low
-
voltage processor is
present. This signal is not a power supply input.
