setting in the application
software, it is assigned to pin
any such as UART, etc. Please
make Open Status about
unused pins.
VIO is connected to VCC in a

In case of the operation with the
battery, we recommend that you
add a capacitor of about 100uF in
view of the voltage drop during
TX/RX
In order to use the built-in
antenna on the module,
please connect PAD13
and PAD14 as short as
possible.
SWD (Serial Wire Debug) is a
high-performance 2-pin debug
port low-pin-count alternative to
JTAG. It can write the application
software and firmware by those
pins through the J-Link Lite.
Example and Applications written
for Keil uVision IDE.
When the customers use the
cable in Nordic DK to use J-LINK
Lite, it will need to implement the
socket on the customers main
board side. The socket will be
"10-pin connector two rows of
1.27mm pitch (Ex:
PSS-720153-05, Hirosugi
instrument). The cable in Nordic
DK has a protection to avoid
reverse connection. In order to
use this cable, please remove the
pin 7 of the socket on main
board.
J-Link Lite is working with 3.3V. It
does not work with 1.8V.

This specification describes desire and conditions especially for mounting.
Desire/Conditions
(1) Environment conditions for use and storage
1. Store the components in an environment of < 40deg-C/90％RH if they are in a moisture
barrier bag packed by TAIYO YUDEN.
2. Keep the factory ambient conditions at < 30deg-C/60％RH .
3. Store the components in an environment of < 25±5deg-C/10%RH after the bag is opened.
(The condition is also applied to a stay in the manufacture process).
(2) Conditions for handling of products
Make sure all of the moisture barrier bags have no holes, cracks or damages at receiving. If
an abnormality is found on the bag, its moisture level must be checked in accordance with 2
in (2).
Refer to the label on the bag.
1. All of the surface mounting process (reflow process) must be completed in 12 months
from the bag sea date.
2. Make sure humidity in the bag is less than 10%RH immediately after open, using a
humidity indicator card sealed with the components.
3. All of the surface mounting process (reflow process including rework process) must be
completed in 168 hours after the bag is opened (inclusive of any other processes).
4. If any conditions in (1) or condition 2 and 3 in (2) are not met, bake the components in
accordance with the conditions at 125deg-C 24hours
5. As a rule, baking the components in accordance with conditions 4 in (2) shall be once.
6. Since semi-conductors are inside of the components, they must be free from static
electricity while handled.(<100V) Use ESD protective floor mats, wrist straps, ESD
protective footwear, air ionizers etc. , if necessary.
7. Please make sure that there are lessen mechanical vibration and shock for this module,
and do not drop it.
8. Please recognize pads of back side at surface mount.
9. Washing the module is not recommended. If washing cannot be avoided, please
test module functionality and performance after thoroughly drying the module.
We cannot be held responsible for any failure due washing the module
10. Please perform temperature conditions of module at reflow within the limits of the

Recommended arrangement of the module
*1 It should not exist a component, conductive plating for chassis and so on in this area.
In addition, main board, chassis etc. may exist outside of the “NO components, NO chassis
plating etc.area”.

1. Power Up Sequence
VCC_NRF power supply rise time (0V to 1.8V) must not exceed 100ms.
2. Recommended Power Circuit
VCC_NRF is the main power supply (1.8 – 3.6V) for this module. The supply voltage range of
VCC_NRF is 1.8V to 3.6V in LDO mode and 2.1V to 3.6V in DCDC mode.
For more information of internal DC/DC converter operation, please refer to chapter 12.1.3 of "nRF51
_Series_Reference_Manual v3.0" by Nordic Semiconductor.
3. Battery operation
When using a small battery (e.g. CR2032), a large capacitor (e.g.100uF low leakage capacitor)
should be placed near the battery. This will reduce the voltage drop especially when the module is
operated at low temperatures
4. Pattern Design Guide
4-1. Power Supply System
Power supply bypass capacitors should be placed close to the VCC_NRF pin of the module. The
VCC_NRF trace should be greater than 0.5mm and a bigger a via diameter is recommended.
4-2. Bypass Capacitor Layout
A parallel combination of a small capacitance (about 10pF) and a large capacitance (1uF to 10uF) is
recommended for bypass capacitors. The GND of the bypass capacitor should be placed close to an
adjacent module GND to ensure the shortest closed loop.
4-3. GND Pattern
Power supply bypass capacitor GND should be placed in proximity of module GND. Wide GND
area must be provided to ensure isolation for each layer.
GND pattern of each layer should be connected to GND area with large number of via.
Control No. (1/1)

Design guide
* If it is difficult to place a bigger via, please increase
the number of vias.
* Bypass capacitors with smaller capacitance must
be placed closer to module.
Line width greater than 0.5mm is recommended.
Via diameter greater than 0.2mm is recommended.

Clock frequency
The evaluation board included with the Nordic Development Kit uses a 16MHz clock. Therefore the
sample code from Nordic is designed to be used with a 16MHz clock. On the other hand, the
EYAGJN series module uses a 32MHz system clock, making it incompatible with the Nordic sample
code (i.e. sample code does not configure HFCLK: XTALFREQ register for 32MHz). To fix this issue,
we need to write the value 0xFFFFFF00 to the UICR (User Information Configuration Register) at
address 0x10001008. Please note that the UICR is erased whenever you download a SoftDevice.
The UICR can be written by using the debug tools:
nrfjprog.exe --snr <your_jlink_debugger_serial_number> --memwr 0x10001008 --val 0xFFFFFF00
Or the following code can be added to the SystemInit function in the system_nRF51.c file, right
before launching the TASK_HFCLKSTART task:
if (*(uint32_t *)0x10001008 == 0xFFFFFFFF)
{
NRF_NVMC->CONFIG = NVMC_CONFIG_WEN_Wen << NVMC_CONFIG_WEN_Pos;
while (NRF_NVMC->READY == NVMC_READY_READY_Busy){}
*(uint32_t *)0x10001008 = 0xFFFFFF00;
NRF_NVMC->CONFIG = NVMC_CONFIG_WEN_Ren << NVMC_CONFIG_WEN_Pos;
while (NRF_NVMC->READY == NVMC_READY_READY_Busy){}
NVIC_SystemReset();
while (true){}
}
32kHz Clock
This module does not installed 32.768kHz crystal. In case of operating without external crystal,
please use following example code in order to enable internal 32.768kHz RC oscillator (32k
RCOSC).
SOFTDEVICE_HANDLER_INIT(NRF_CLOCK_LFCLKSRC_RC_250_PPM_TEMP_1000MS_CALIBRATION, false);
Note that when you choose to use the RC oscillator, it will add around 10uA average current
consumption compared to a 20ppm external crystal.
