All voltage values are with respect to VSS.
For test conditions shown as MIN, MAX, or NOM, use the appropriate value specified in the recommended operating conditions table.
§ For VC33, all typical values are at DVDD = 3.3, CVDD = 1.8 V, TC (case temperature) = 25°C.
Pins with internal pullup devices: TDI, TCK, and TMS. Pin with internal pulldown device: TRST.
# Pins D0-D31 include internal bus keepers that maintain valid logic levels when the bus is not driven (see Figure 9).
|| Actual operating current is less than this maximum value. This value was obtained under specially produced worst-case test conditions, which
are not sustained during normal device operation. These conditions consist of continuous parallel writes of a checkerboard pattern at the
maximum rate possible. See TMS320C3x General-Purpose Applications (literature number SPRU194).
kfx is the PLL output clock frequency.
