† _{All nominal values are at VDD = 5 V, TA = 25°C.}
* On products compliant to MIL-PRF-38535, this parameter is not production tested.
NOTES: 2. All input and output voltage levels are TTL-compatible.
4. Pins with internal pullup devices: TDI, TCK, TMS. Pin with internal pulldown device: TRST.
5. f_x is the input clock frequency. The maximum value (MAX) for the 320C40-40, 320C40-50, and 320C40-60 is 40, 50, and 60 MHz,
respectively.
