I2C (I2C 201)
The I2C interface acts as a master. No pull-up resistors are provided meaning that the UUT's pull-up
resistors determine the voltage level for the inactive state.
The SCL output and SDA input/output are protected against short circuit by means of a 100Ω series
resistor. Transient Voltage diodes protect the outputs against voltages above 5V if such a voltage is
inadvertently applied to the test pins.
Applying more than 8V for longer periods to these test pins may damage the eC-test-mate.
Currently, the SCL clock frequency is fixed at 100kHz
Associated test command(s):
• I2C_START
• I2C_WRITE
• I2C_READ
• I2C_STOP
Programmable Power Supply (Supply 201)
One independently programmable power supply is provided in order to power the board under test.
The output voltage of the supplies is programmable from 1.26..24V (in 12-bit resolution: 6 mV steps).
This power supply is identical to the one of Type I. See Programmable Power Supply (Supply 101) for full
specifications.
Board Presence
See Board Presence for a detailed description of this function.
Note: this pin MUST be connected to GND on the PCB under test.
