Electrical and Thermal
Characteristics
This section provides AC and DC electrical specifications and thermal characteristics for
the PC8265A.
DC Electrical Characteristics
This section describes the DC electrical characteristics for the PC8265A. Table 3 shows
the maximum electrical ratings.
Notes:
1. Absolute maximum ratings are stress ratings only; functional operation (see Table 4)
at the maximums is not guaranteed. Stress beyond those listed may affect device
reliability or cause permanent damage.
2. Caution: VDD/SYN must not exceed V
DDH
by more than 0.4V at any time, including
during power-on reset.
3. Caution: V
DDH
can exceed VDD/SYN by 3.3V during power on reset by no more than
100 ms. V
DDH
should not exceed VDD/SYN by more than 2.5V during normal
operation.
4. Caution: V
IN
must not exceed V
DDH
by more than 2.5V at any time, including during
power-on reset.
Table 4 lists recommended operational voltage conditions.
Notes:
1. Caution: These are the recommended and tested operating conditions. Proper device
operation outside of these conditions is not guaranteed
2. CPU frequency less than or equal to 200 MHz
3. CPU frequency greater than 200 MHz but less than or equal 233 MHz
4. CPU frequency greater than 233 MHz
Note:
V
DDH
and V
DD
must track each other and both must vary in the same direction – in the
positive direction (+5% and +0.1 V
DC
) or in the negative direction (-5% and -0.1 V
DC
).
