AC Parameters

Explanation of the AC

Symbols

Each timing symbol has 5 characters. The first character is always a “T” (stands for

Time). The other characters, depending on their positions, stand for the name of a sig-

nal or the logical status of that signal. The following is a list of all the characters and

what they stand for.

Example: TXHDV = Time from clock rising edge to input data valid.

TA = -40°C to +125°C (Automotive temperature range); VSS = 0V; 3.135V < VCC < 3.465V

The maximum applicable load capacitance for Port 1 and 3 is 80 pF. Timings will be

guaranteed if these capacitances are respected. Higher capacitance values can be

used, but timings will then be degraded.
