For conditions shown as MIN/MAX, use the appropriate value specified in recommended operating conditions.
All typical values are at V
= 5 V, T = 25°C.

* This parameter is not production tested.
NOTES: 5. All input and output voltage levels are TTL compatible.
7. Pins with internal pullup devices: INT0−INT3, MC/MP, RSV0−RSV10. Although RSV0−RSV10 have internal pullup devices,
external pullups should be used on each pin as identified in the pin function tables.
8. 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 to both primary and expansion buses at the maximum rate possible. See Calculation of TMS320C30 Power
Dissipation Application Report (literature number SPRA020).
