...the world's most energy friendly microcontrollers EFM32HG210 Errata, Chip Rev. B F64/F32 This document describes errata for the latest revision of EFM32HG210 devices. ...the world's most energy friendly microcontrollers 1 Errata This document contains information on the errata of the latest revision of this device. For errata on older revisions, please refer to the errata history for the device. The device data sheet explains how to identify chip revisions, either from package markings or electronically. In addition to the errata noted below, the errata for the ARM Cortex-M0+ r0p1 (www.arm.com) also applies to this device. 1.1 Chip revision B Table 1.1. Erratas ID Title/Problem Effect Fix/Workaround IDAC_E101 IDAC output current degradation Due to an undefined shut-down state of the IDAC, powered devices that do not use the IDAC continuously might experience some degradation in the current output over the lifetime of the device. The degradation is very small when the device is used at room temperature, but the output current will fall well outside specs if the device is exposed to higher temperatures for longer periods of time. If the IDAC output current stability is crucial to the application, the IDAC should never be completely disabled while the device is powered. Leaving the IDAC enabled in the lowest output code setting with duty-cycling enabled consumes ~50 nA extra current and eliminates the problem. The PCNT Pulse Width Filter does not work as intended. Do not use the pulse width filter, i.e. ensure FILT = 0 in PCNTn_CTRL. The current output of the IDAC might degrade over time. PCNT_E102 PCNT Pulse Width Filtering does not work 1.2 Older Revisions Erratas for older revisions can be found at the Silicon Laboratories homepage: www.silabs.com/32bit-errata 2016-01-06 - EFM32HG210FXX - d0303_Rev1.00 2 www.silabs.com ...the world's most energy friendly microcontrollers 2 Revision History 2.1 Revision 1.00 January 6th, 2016 Moved to revision B.
