Figure 15. Equivalent Analog Input Circuit
1.
Parasitic capacitance due to package, pin to pin, and pin to package base coupling. (1.8pf)
2.
Parasitic capacitance due to the chip bond pad, ESD protection devices and signal routing.
(2.04pf)
3.
Equivalent resistance for the ESD isolation resistor and the channel select mux. (500 ohms)
4.
Sampling capacitor at the sample and hold circuit. Capacitor 4 is normally disconnected from the
input and is only connected to it at sampling time. (1pf)

Table 25. JTAG Timing 1, 3
Operating Conditions: VSS = VSSA = 0 V, VDD = VDDA = 3.0–3.6 V, TA = –40° to +85°C, CL 50 pF
1.
Timing is both wait state and frequency dependent. For the values listed, T = clock cycle. For 80MHz
operation, T = 12.5ns.
