August 22, 2012 CP2110 Errata Datasheet Errata Status Summary The Documentation Errata is applicable to the following document: • CP2110 Data Sheet Revision 1.1 Errata # D1 Title ROM Programming Voltage Impact Data Sheet Minor Issue Exists Impact Definition: Each erratum is marked with an impact, as defined below: • Minor—Workaround exists. • Major—Errata that do not conform to the data sheet or standard. • Information—The device behavior is not ideal but acceptable. Typically, the data sheet will be changed to match the device behavior. Errata Details D1. ROM Programming Voltage Description: The data sheet incorrectly indicates that VDD must remain at 3.3 V or higher to successfully write to the configuration ROM. Instead, the voltage on the VIO pin must remain at 3.3 V or higher when writing to the configuration ROM. Impact: For systems that connect VDD and VIO together, there is no impact. For systems that have a separate voltage source for VIO and are configuring the ROM in-system, VIO must remain at 3.3 V while programming is in progress. Resolution: This note will be fixed in the Revision 1.2 of the CP2110 Data Sheet. 400 West Cesar Chavez, Austin, TX 78701 (512) 416-8500 FAX (512) 416-9669 www.silabs.com CP2110ER082212
