IT530 - Data Sheet
1 Overview
1.1 General
The Fastrax IT530 is an OEM GPS receiver module with the Mediatek MT3339 receiver. The module has ultra
small form factor 9.6x9.6 mm, height is 1.85 mm nominal (2.15 mm max) and can be assembled with SMT
reflow soldering. The Fastrax IT530 receiver provides extremely low power and very fast TTFF together with weak
signal acquisition and tracking capability to meet even the most stringent performance expectations.
The IT530 provides complete signal processing from antenna input to host port UART and location data output is
in NMEA protocol. The module requires a main and a backup power supply. The host port is configurable to
UART during power up. Host data and I/O signal levels are 2.8V CMOS compatible and inputs are 3.6V tolerable.
The IT530 supports a new feature called AlwaysLocate™, which is an intelligent controller of the IT530 power
saving mode. Depending on the environment and motion conditions, the module can adaptively adjust the
navigation activity in order to achieve a balance in positioning accuracy, fix rate and power consumption; typical
power consumption varies between 2… 8 mW.
The module also supports autonomous A-GPS. It is self-assisted since the EASY™ (Embedded Assist System, also
called as) ephemeris extension is embedded in the software without any resources required from the host. The
EASY™ data is stored on internal flash memory and allows fast TTFF typ. 3 seconds over 3 days.
The IT530 contains also an AIC (Active Interference Cancellation), which provides state-of-art narrow band (CW)
interference and jamming elimination up to 12 CW jammers < -80dBm.
The module also supports a logging feature called LOCUS, which enables automatic logging of position data to
internal flash memory. The logging capacity is >16 hrs typ. @ 15 sec storage interval.
The antenna input supports passive and active antennas with excellent out-of-band blocking rejection and
provides also an input for externally generated antenna bias supply.
This document describes the electrical connectivity and main functionality of the Fastrax IT530 OEM GPS Receiver
module.

3 Connectivity
3.1 Signal Assignments
The I/O signals are available as soldering (castellated) pads on the bottom side of the module. These pads are
also used to attach the module on the motherboard. All digital I/O signal levels are 2.8V CMOS compatible
(except TIMER and 32K/DR_INT that are 1.2V CMOS) and inputs are 3.6V tolerable. All unconnected I/O signals
can be left unconnected when not used, unless instructed to use external pull up/down resistor.
