Product Technical Specifications
□ Normal □ Internal Use Confidential □ Restricted Confidential
Notes: *2. Do not pull pin143 WAKEUP_OUT to high; otherwise boot will fail.
*3. Pull Pin144 WAKEUP_IN to VREF with a 100k resistor and keep it high before
system boot process is complete.
*4. Pull pin142 POWER_ON to VREF with a 100k resistor for stability considerations.
*6. Refer to section 2.3, for more information please check USB2.0 standard
*8. Pull pin87 USB detect to VREF with a 100k resistor to enable module USB, pull
pin87 low to disable module USB, CPU USB PHY consumes some current when
USB is enabled.
*9. Do not pull pin52 to high before the system boot process is complete.
*10. Leave unused pins floating
*11. Reserve test points on pin52/86/88/106/107 for debug purpose if possible.
*12. If voltage level of digital I/O from the other side is not compatible with module,
level shifter is recommended to transfer the voltage level to 1.8V.
Note2,3,4,8,9,10 must be followed otherwise module may fail or malfunction.
Table 5. Digital I/O characteristics
Below is the I/O default setting table to describe the level. It’s recommended to follow the
pulling High or Low to choose a suitable GPIO for application.
PU: Pull Up.
PD: Pull Down
NP: Non-Pull
