Notes:
2. TA is the “instant on” case temperature.
3. See the last page of this specification for Group A subgroup testing information.
4. If VCCIO is not specified, the device can be operating in either 3.3V or 5V I/O mode; VCC=VCCINT.
5. IOH = –2 mA, IOL = 2 mA for SDO.
6. When the I/O is three-stated, the bus-hold circuit can weakly pull the I/O to a maximum of 4.0V if no leakage current is allowed. This voltage is lowered significantly
by a small leakage current. Note that all I/Os are three-stated during ISR programming. Refer to the application note “Understanding Bus Hold” for additional
information.
7. These are absolute values with respect to device ground. All overshoots due to system or tester noise are included.
8. Not more than one output should be tested at a time. Duration of the short circuit should not exceed 1 second. VOUT = 0.5V has been chosen to avoid test
problems caused by tester ground degradation.
9. Tested initially and after any design or process changes that may affect these parameters.
10. Measured with 16-bit counter programmed into each logic block.
