The JN5121-xxx-Myy module family provides designers with a ready made component which allows IEEE802.15.4 [1]
wireless applications, including ZigBee, to be quickl y and easily inclu ded in product designs. The m odules integrate
all of the RF components, removing the need to perform expensive RF design and test. Products ca n be designed by
simply connecting sensors and switches to the module IO pins. The modules use Je nnic’s single chip IEEE802.15. 4
Wireless Microcontroller, allowing designers to make use of the extensive chip development support material.
Hence, this range of modules allows designers to bring wirel ess applications to market in the minimum time with
significantly reduced development effort and cost.
Three basic modules are available: JN5121- xxx-M0 0 (standard module with on board ceramic antenna), JN5121-xxxM01 (standard module with SMA connector for use with externa l antennae) and JN5121-xxx-M02 (high RF power,
improved sensitivity module for extended range applications). Each of these modules can be supplied with a range of
protocol stacks, including a simple IEEE802.15.4 protocol for point to poin t and star applications and a ZigBee mesh
networking stack. The variants available are described below.

4.2. Pin Descriptions
All pins behave as described in the JN5121 datasheet [2], with the exception of the following:
4.3. Power Supplies
A single power supply pin, VDD is provided. Separate analogue (VSSA) and digital (GND) grounds are provided.
These should be connected together at the module pins.
4.4. SPI Memory Connections
SPISWP is a write protect pin for the serial flash memory. This should be held low to inhibit writes to the flash device.
SPISSZ is connected to SPI Slave Select 0 on the JN5121.
SPISSM is connected to the Slave Select pin on the memory.
This configuration allows the flash memory device to be programmed using an external programmer if required. T he
JN5121 should be held in reset by taking RESETN low. The memory can then be programmed over the UART by
using the programming mode described in
be programmed by connecting a SPI programmer to SPISSM, SPICLK, and SPIMISO and directly loading the code
into the memory.
For normal operation of the module, SPISSZ should be connected to SPISSM.

A.7 Federal Communication Commission Interference Statement
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation. This equipment generates,
uses, and can radiate radio frequency energy and, if not installed and used in accordance with
the instructions, may cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception, which can be determined by turning
the equipment off and on, the user is encouraged to try to correct the interference by one of the
following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
- Consult the dealer or an experienced radio/TV technician for help.
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.
FCC Caution: Any changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate this equipment.
WARNING!
FCC Radiation Exposure Statement:
This portable equipment with its antenna complies with FCC’s RF radiation exposure limits set
forth for an uncontrolled environment. To maintain compliance follow the instructions below;
1. This transmitter must not be co-located or operating in conjunction with any other antenna or
transmitter.
2. Avoid direct contact to the antenna, or keep it to a minimum while using this equipment.
This transmitter module is authorized to be used in other devices only by OEM
integrators under the following condition:
The transmitter module must not be co-located with any other antenna or transmitter.
As long as the above condition is met, further transmitter testing will not be required. However,
the OEM integrator is still responsible for testing their end-product for any additional compliance
requirements required with this module installed (for example, digital device emissions, PC
peripheral requirements, etc.).
High Power Module usage limitation
The high power module variant FCC ID TYOJN5121M4 is classified as ‘mobile’ device pursuant
with FCC § 2.1091 and must not be used at a distance of < 20 cm (8”) from any nearby people.
IMPORTANT NOTE: In the event that these conditions can not be met (for certain
configurations or co-location with another transmitter), then the FCC authorization is no longer
considered valid and the FCC ID can not be used on the final product. In these circumstances,
the OEM integrator will be responsible for re-evaluating the end product (including the
transmitter) and obtaining a separate FCC authorization.
The OEM integrator has to be aware not to provide information to the end user regarding how to
install or remove this RF module in the user manual of the end product.
The user manual for the end product must include the following information in a prominent
location;
“To comply with FCC’s RF radiation exposure requirements, the antenna(s) used for this
transmitter must not be co-located or operating in conjunction with any other antenna or
transmitter.”
End Product Labelling
The final ‘end product’ should be labelled in a visible area with the following:
“Contains TX FCC ID: TYOJN5121M0, TYOJN5121M4 or TYOJN5121M6 ” to reflect the
version of the module being used inside the product.
RoHS Compliance
JN5121-xxx-Myy devices meet the requirements of Direct ive 2002/95/EC of the European Parliament and of the
Council on the Restriction of Hazardous Substance (RoHS).
