TC1765
Preliminary
Parameter Interpretation
The parameters listed on the following pages partly represent the characteristics of the
TC1765 and partly its demands on the system. To aid in interpreting the parameters
right, when evaluating them for a design, they are marked in column “Symbol”:
CC (Controller Characteristics):
The logic of the TC1765 will provide signals with the respective timing characteristics.
SR (System Requirement):
The external system must provide signals with the respective timing characteristics to
the TC1765.
Pin Classes
The TC1765 has three classes of digital I/O pins:
– Class A pins, which are 3.0 to 5.25 V voltage pins
– Class B pins, which are 2.5 V nominal voltage pins (input tolerant for 3.3 V)
– Class C pins, which are 2.5 V nominal voltage pins only
Table 8 shows the assignments of all digital I/O pins to pin classes and to V_DD power
supply pins.
