1. General
1.1
Overview
The BoT-nLE521 module is a cost-effective, low-power, true system-on-chip (SoC) for
Bluetooth Smart (Bluetooth low energy) applications. It enables robust BLE master or slave
nodes to be built with very low total bill-of-material costs. BoT-nLE521 combines an
excellent RF transceiver with an industry-standard enhanced Cortec-M4 CPU, in-system
programmable flash memory, 24kB RAM, and many other powerful supporting features
and peripherals. The BoT-nLE521 is suitable for systems where very low power
Consumption is required. Very low-power sleep modes are available. Short transition times
between operating modes further enable low power consumption.

Regulator
The following internal power regulator alternatives are supported:
• Internal LDO regulator
• Internal DC/DC regulator
The LDO is the default regulator.
Using the DC/DC regulator will reduce current consumption compared to when using the LDO
regulator, but the DC/DC regulator requires an external LC filter to be connected, as shown in Figure.

32.768KHz Crystal Oscillator
The BoT-nLE521 external 32.768KHz Crystal does not required for BLE mode
If you choose to use an internal 32.768kHz oscillator, an average of 10uA of current is consumed
compared to an external crystal.
The ANT specification requires ± 50ppm accuracy for a 32.768kHz clock. The internal 32.768kHz
oscillator may not meet specifications.
BoT-nLE521 F/W does not yet support ANT Mode.

Circuit diagram of the 32.768 kHz crystal oscillator
The load capacitance (CL) is the total capacitance seen by the crystal across its terminals and is given by:
C1 and C2 are ceramic SMD capacitors connected between each crystal terminal and ground. Cpcb1 and
Cpcb2 are stray capacitances on the PCB.

FCC Statement
FCC Statement
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation. Changes or modifications not expressly approved
by the party responsible for compliance could void the user's authority to operate the equipment.
FCC Radiation Exposure Statement
This modular complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This
transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
If the FCC identification number is not visible when the module is installed inside another device,
then the outside of the device into which the module is installed must also display a label referring to the
enclosed module.
This exterior label can use wording such as the following: “Contains Transmitter Module
FCC ID: 2APB6-BoT-nLE521 Or Contains FCC ID: 2APB6-BoT-nLE521
When the module is installed inside another device, the user manual of the host must contain below warning
statements;
1. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) This device may not cause harmful interference.
(2) This device must accept any interference received, including interference that may cause
undesired operation.
2. Changes or modifications not expressly approved by the party responsible for compliance could void the
user's authority to operate the equipment.
The devices must be installed and used in strict accordance with the manufacturer's instructions as described
in the user documentation that comes with the product
Any company of the host device which install this modular with limit modular approval should perform the
test of radiated emission and spurious emission according to FCC part 15C : 15.247 and 15.209 requirement,
Only if the test result comply with FCC part 15C : 15.247 and 15.209 requirement then the host can be sold
legally.
