Product Specification GPS RADIONOVA M20050-1-PS-1.0
Host Interface
UART Interface
The UART converts bytes of data to and from asynchronous start -stop bit streams as binary electrical
impulses.
The port contains a 16-byte FIFO, and 256 bytes of URAM. The bit rates are
selectable from 4800, 9600,
38400 and 115200 bps.
The IO level from the UART port are CMOS compatible, however for RS232 compatibility the use
of external
level shifters will be required. The hardware configuration of the port baud can be
changed dynamically by the
use of commands. These will be active and saved as long as the
VBACKP supply is applied.
Power Supply
The M20050-1 uses two DC supply inputs, VBCKUP to power the RAM and RTC sections of the
receiver, and
VCC to power the digital and processing sections. VBCKUP is to be applied all the time
to keep these sections alive.
VCC can be removed to initiate a backup power save mode (See page
10). VBCKUP can be removed if a battery is
also used at VBCKUP to maintain this supply. The
supply is internally regulated for 2.8V meaning the external supply
is versatile for a range of voltage
levels.
TM (1PPS)
TM is a one pulse per second output from the receiver providing uses for timing purposes. The
pulse width is 100ms.
HRST (Hardware Reset Pin)
The External reset pin is default high by an internal 75Kohm and should be left floating if not used.
To initiate a reset
the pin needs to be pulled low. The module also initiates a reset if the VCC drops
below the minimum 2.8V supply.

Power Management
The M20050-1 has three power saving modes.
•
Standby mode
•
Back up mode
•
Periodic mode
Standby Mode
Standby mode is a power saving mode that shuts down the RF section of the module and puts the
processor into
a standby mode. The RTC is kept alive and the RAM power is maintained to keep the
module configuration.
The standby state can be initiated either with a hardware signal to Pin26 or by using a command.
Hardware controlled Standby:
Enable standby mode by a low state to pin 26 (HW_S). To wake the module back to full power a high state
needs to be applied to pin 8. If Pin 8 is not to be used then it must be kept floating (not connected).
Standby mode command:
Software on the host needs to send the “PMTK161 command through the UART interface.
Command

Current consumption (Typ)

M20050-1 enters standby mode
<500uA
Any byte
M20050-1 wakes up from standby mode
Back up mode
To enter backup mode the VCC simply needs to be removed. Once initiated the RTC and all
configuration is saved
along with any ephemeris data to allow quick TTFF once the VCC is re-applied.
BV needs to be applied always for backup mode to run correctly.
Periodic mode
Periodic mode is a module controlled mode that reduces current consumption by only waking the
module for short
periods to maintain fix data. The periodic state is user configured. Contact Antenova
for more information and a
user command manual.

EPO (Extended Prediction Orbit) data service
The EPO allows the use of up to a 30-day orbit prediction that can be used to aid the module for an
instant fix
solution.
•
A proxy server on the customer’s side to update EPO files from the MTK server daily.
•
Application software to access the proxy server through the internet (optional if host device
can access
internet
•
Software on host device to send EPO data to M20050-1 module to allow instant fix by using EE
data.
Please contact Antenova for more information. Requires permission from MTK to use
service.
EASY (Self-Generated Orbit prediction)
The module supports EASYTM (Embedded Assisted System) is a Self-Generated Orbit Prediction
feature. It
provides up to 3 days GPS orbit prediction ability without the need for any host CPU
porting or internet
connection requirements.
EASY works as embedded software which accelerates TTFF by predicting satellite navigation
messages from received ephemeris. EASY is a fully automated receiver task that is efficiently
scheduled and computed in free
time of every second after a GNSS navigation solution.
EASY is default off and can be enabled by a PMTK command.
AIC (Active Interference Cancellation)
The AIC feature provides effective narrow-band interference and jamming elimination. The GPS
signal can
be recovered from the jammed signal and allows users to obtain better navigation
quality. This can be
beneficial since many of today’s devices have increasing functionality with
regards to transmitters with
many on-board antennas.

External Matching
The M20050-1 module uses matching circuit components on the host PCB to fine-tune the on-
board
antenna to each specific application. This “external matching” allows compensating for the
detuning of the
antenna caused by various components that can be close to the M20050-1
module in the
actual application (plastic case, battery, speakers etc).
The external matching must be placed on the host PCB from pads AT1(Pad 1) and AT2 (Pad
28). A single component from each pin to GND is all that is required. This should be placed close
to the modules pads.
Schematic
In the example above AT1 only required a 0R resistor and AT2 uses a small 1.8nH inductor to
tune the antenna. Both components should be designed in as both may be required for the
intended device.
Type of Matching Components
•
Capacitors:
•
Use 0402, COG components
•
Inductors:
•
High-Q, wire wound inductors in 0402 sizes are recommended for maximum performance,
e.g. Murata LQW15 series
•
Good quality multi-layer type inductors (e.g. Murata LQG15 series) can also be
used as a
lower cost alternative
External Antenna Support
A low cost external circuit can be used to provide external antenna support. Please contact Antenova for
more
information, and example circuit.

Internal Antenna Clearance
The M20050-1 module internal antenna requires a small clearance on the host PCB to
operate. The
clearance means that no Ground or tracks of any kind can be within this area. This
must also be
clear through the entire PCB stack up. The minimum area needed clear is 6mm X
4.87mm.

Module Placement Guidelines
Due to the internal antenna, care must be taken when defining the placement of the module on the
host PCB.
Here are some guidelines that should be used when deciding the position of the module.
•
The module top edge must be placed almost level with the edge of the host PCB
•
The edge of the host PCB that the module is to be placed at must be a minimum of 40mm in
length.
•
The central placement of the module is advised. However, an offset placement is also possible.
•
For an offset closer to the PCB edge to the right side of the module, a minimum of 10mm
distance is
required to the edge of the host PCB.

Part No. M20050-1
Antennas for Wireless M2M Applications

Product Specification GPS RADIONOVA M20050-1-PS-1.0
•
The antenna uses the host PCB ground to effectively radiate. As such, a GND plane must
be placed
on the host PCB on at least one layer.
•
In the example below, the only area void of GND is the antenna keep-out area. The solder mask
is removed to make the copper visible.
•
An ideal stack-up for a host PCB would be to use the top and bottom layers as GND
planes, while
using the internal layers for any signal and power planes. This not only
helps the GPS antenna to
perform effectively, but also helps to reduce any potential
noise issues that can be associated with
mixed signal PCB’s.
•
An example below shows a 4-layer host PCB, GND flooding all available space not used
by
signals or components.

Placement
Typical placement systems used for any BGA/LGA package are acceptable. Recommended nozzle
diameter for placement: 5mm.
Soldering Paste
Use of “No Clean” soldering paste is strongly recommended, as it does not require cleaning
after the
soldering process has taken place. An example of suitable soldering paste is Alpha
OM350.
Soldering
The recommended soldering profile for M20050-1 is shown below. However, it is the responsibility
of the
Contract Manufacturer to determine the exact reflow profile used, taking into consideration
the parameters of
the host PCB, solder paste used, etc.

Multiple Soldering
The M20050-1 module can be submitted up to 2 reflow soldering processes.
Upside-down soldering is acceptable but it is recommended that the Contract Manufacturer
qualify the
process before mass production. The second reflow must take place within the
recommended floor life limit
(MSL3). Please contact Antenova for further information.
Hand Soldering
Hand-soldering and rework of the M20050-1 module is acceptable, however care must be taken to avoid
short
circuits due to the small size of the module pads.
