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.

TABLE 1-1: PIN DESCRIPTION (CONTINUED)
Pin Name
Description
Function
15 WAKE_HW
Hardware wake from Dormant state. Setting the
WAKE_HW (pin15) high wakes the module from Dor-
mant mode. During the module power up, if
WAKE_HW pin is flipped high and low for three
cycles (putting the WAKE_HW pin into high, low, and
then high again is considered as one flip cycle) in the
first five seconds, then the module performs a factory
Reset. If the WAKE_SW pin is high when a factory
Reset is performed, the factory Reset is a full reset.
Otherwise, it is a partial reset that retains the device
name, private service and scripts. Set WAKE_HW
pin to low in order to lower power consumption in
Active-high; internal pull down
Deep Sleep and Dormant modes.
CAUTION
A full factory Reset erases scripts and sets the
device name to the serialized name. For more
information, refer to the SF Command in the
RN4020 Bluetooth Low Energy User's Guide
(DS70005191).

be halted, assert RTS to high. RTS pin operates
independently from the CTS (pin 14).
