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 EFM32LG900 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. 2015-03-16 - EFM32LG900FXX - d0328_Rev1.20 17 www.silabs.com ...the world's most energy friendly microcontrollers 3.5 Wafer Description Table 3.4.

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 - EFM32LG900FXX - d0328_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. 2015-03-16 - EFM32LG900FXX - d0328_Rev1.20 19 www.silabs.com ...the world's most energy friendly microcontrollers 4 Chip Marking, Revision and Errata 4.1 Errata Please see the errata document for EFM32LG900 for description and resolution of device erratas.
