Description
Microchip’s RN4020 Bluetooth Low Energy Module pro-
vides a highly integrated solution for delivering low-power
Bluetooth 4.1 solutions. The advanced command inter-
face offers rapid time to market. The RN4020 module
complies with Bluetooth specification version 4.1. The
module integrates RF, a baseband controller, and a com-
mand API processor, making it a complete Bluetooth Low
Energy solution. The RN4020 can be used with ultra-low
cost microcontroller for intelligent Bluetooth Low Energy
applications. For simple sensor applications, the RN4020
internal scripting capabilities enable basic functions to be
implemented without the need for external host MCU or
software development tools.

TO OUR VALUED CUSTOMERS
It is our intention to provide our valued customers with the best documentation possible to ensure successful use of your Microchip
products. To this end, we will continue to improve our publications to better suit your needs. Our publications will be refined and
enhanced as new volumes and updates are introduced.
If you have any questions or comments regarding this publication, please contact the Marketing Communications Department via
Most Current Data Sheet
To obtain the most up-to-date version of this data sheet, please register at our Worldwide Web site at:
http://www.microchip.com
You can determine the version of a data sheet by examining its literature number found on the bottom outside corner of any page.
The last character of the literature number is the version number, (e.g., DS30000000A is version A of document DS30000000).
Errata
An errata sheet, describing minor operational differences from the data sheet and recommended workarounds, may exist for current
devices. As device/documentation issues become known to us, we will publish an errata sheet. The errata will specify the revision
of silicon and revision of document to which it applies.
To determine if an errata sheet exists for a particular device, please check with one of the following:
• Microchip’s Worldwide Web site; http://www.microchip.com
• Your local Microchip sales office (see last page)
When contacting a sales office, please specify which device, revision of silicon and data sheet (include literature number) you are
using.
