3.2 Alternate Functionality Pinout
A wide selection of alternate functionality is available for multiplexing to various pins. This is shown in
Table 3.2 (p. 9). The table shows the name of the alternate functionality in the first column, followed
by columns showing the possible LOCATION bitfield settings.
Note
Some functionality, such as analog interfaces, do not have alternate settings or a LOCATION bitfield. In these cases, the pinout is shown in the column corresponding to LOCATION 0.

3.4 Bonding Instructions
All pads should be bonded out, with the exception of the pads labeled “NC” and listed as “Do not connect”
in Table 3.1 (p. 5) . Gold bond wires are recommended for these devices.
All three voltage regulator output decouple pads (DEC_0, DEC_1, DEC_2) must be bonded out and
electrically connected on the PCB. In the packaged devices, these three pads are all bonded to a single
DECOUPLE pin.
If the USB feature of EFM32WG900 will be used, all of the USB pads must be bonded out, and
• both USB_VREGO_0 and USB_VREGO_1 must be bonded out and electrically connected on the
PCB. In the packaged devices, these two pads are both bonded to a single USB_VREGO pin.
• both USB_VREGI_0 and USB_VREGI_1 must be bonded out and electrically connected on the PCB.
In the packaged devices, these two pads are both bonded to a single USB_VREGI pin.

Note: This is the Expected Known Good Die yielded per wafer and represents the batch order quantity (one wafer).
3.5.1 Environmental
Bare silicon die are susceptible to mechanical damage and may be sensitive to light. When bare die
must be used in an environment exposed to light, it may be necessary to cover the top and sides with
an opaque material.
For additional Quality and Environmental information, please see:
http://www.silabs.com/support/quality/pages/default.aspx.
3.6 Wafer Storage Guidelines
It is necessary to conform to appropriate wafer storage practices to avoid product degradation or contamination.
•
•
•
•
Wafers may be stored for up to 18 months in the original packaging supplied by Silicon Labs.
Wafers must be stored at a temperature of 18 - 24 °C.
Wafers must be stored in a humidity-controlled environment with a relative humidity of <30%
Wafers should be stored in a clean, dry, inert atmosphere (e.g. nitrogen or clean, dry air).
3.7 Failure Analysis (FA) Guidelines
Certain conditions must be met for Silicon Laboratories to perform Failure Analysis on devices sold in
wafer form.
• In order to conduct failure analysis on a device in a customer-provided package, Silicon Laboratories
must be provided with die assembled in an industry standard package that is pin compatible with
existing packages Silicon Laboratories offers for the device. Initial response time for FA requests that
meet these requirements will follow the standard FA guidelines for packaged parts.
2015-03-16 - EFM32WG900FXX - d0325_Rev1.20
18
www.silabs.com
...the world's most energy friendly microcontrollers
• If retest of the entire wafer is requested, Silicon Laboratories must be provided with the whole wafer.
Silicon Laboratories cannot retest any wafers that have been sawed, diced, backgrind or are on tape.
Initial response time for FA requests that meet these requirements will be 3 weeks.
