All input and output voltage levels are TTL compatible.
For ’C31, all typical values are at VDD = 5 V, TA = 25°C. For ’LC31, all typical values are at VDD = 3.3 V, TA = 25°C.
§ Pins with internal pullup devices: INT3 INT0, MCBL / MP.
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).
# fx is the input clock frequency.
* This parameter is not production tested.
NOTE 3: All voltage values are with respect to VSS. All input and output voltage levels are TTL-compatible. CLKIN can be driven by a CMOS
clock.
