CP2110 Errata
Datasheet Errata Status Summary
The Documentation Errata is applicable to the following document:
• CP2110 Data Sheet Revision 1.1
Errata #
ROM Programming Voltage
Data Sheet
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.
