Preliminary data sheet
NXP Semiconductors
1. Signals beginning with ‘n’ are Active LOW.
2. The SCLK pin can source up to 12 mA and sink up to 20 mA. See ‘DC Characteristics’.
3. Schmitt trigger input; see ’DC Specifications’, page 31 for triggers points and hysteresis.
4. Input only for JTAG boundary scan mode.
5. Output only for JTAG boundary scan mode.
6. The internal pullup and pull-down resistance on all digital I/O pins is 50 k
7. When used as SMBCLK, this pin must have a resistor.
8. The RESET STATE is defined as the state during power-on reset.
9. The STANDBY STATE is defined as the state when the device is in standby. During this state,
I/O cells are forced to input (Input), output driving low (LOW), output driving high (HIGH), or their
current state is preserved (No Change). In some case, function selection has an overall effect on the standby state.
10.All unused USB Device pins with a differential pair must be pulled
to ground with a 15 k
resistor.

JTAG Clock. This signal should be externally
pulled-up to VDD with a 33 k
resistor.
JTAG Data Out. This signal should be externally
pulled up to VDD with a 33 k
resistor.
JTAG Test Mode select. This signal is internally
pulled-up to VDD.
Test Pin 0. Internally pulled up to VDD. For Normal
