EB-5662RE
High Performance GPS Engine Board

Product Description

Product Description

EB-5662RE GPS module features high sensitivity, low power and ultra small form factor. This GPS
module is powered by SiRF Star IV, it can provide you with superior sensitivity and performance
even in urban canyon and dense foliage environment. With SiRF CGEE (Client Generated
Extended Ephemeris) technology, it predicts satellite positions for up to 3 days and delivers
CGEE-start time of less than 15 seconds under most conditions, without any network assistance.
Besides, MicroPower Mode allows GPS module to stay in a hot-start condition nearly continuously
while consuming very little power. EB-5662RE is suitable for the following applications:

 Automotive navigation
 Personal positioning
 Fleet management
 Mobile phone navigation
 Marine navigation

Product Features

 SiRF Star IV high performance GPS Chipset
 Very high sensitivity (Tracking Sensitivity: -163 dBm)
 Extremely fast TTFF (Time To First Fix) at low signal level
 Support UART interface
 Built-in LNA(with in CHIP)
 Compact size (22.4mm x 17mm x 3.0mm) suitable for space-sensitive application
 One size component, easy to mount on another PCB board
 Support NMEA 0183 V3.0 (GGA, GSA, GSV, RMC, VTG, GLL, ZDA)
 Support OSP protocol
 MEMS Support : 3-axis Magnetometer for compass heading for “Point and Tell” feature
 MicroPower Mode(MPM) : Reduce MPM current consumption from <500 uA to < 125 uA

<Note>

1. GPIO is 1.8V Level

2. The ON_OFF pin commands the EB-5662RE ON or OFF. The turn ON command is a
hardware feature of the Power Control FSM when sensing a rising edge on the pin. The turn
OFF command is a software feature based on interrupts related to rising and/or falling edges
and/or sensing of pin levels.

3. The WAKE_UP pin is an output from the EB-5662RE used to enable an external PMIC. A low
on this output indicates that the EB-5662RE is in one of its low-power states (KA-only,
Hibernate, or Standby mode) and requires no more than 60μA of current on the VIO_18 input.
A high on this output indicates that the EB-5662RE is in operational mode requiring an
external regulator to provide enough current on both the VIO_18 and VREG_18 inputs to
handle the peak current requirements of the EB-5662RE.

GPS Active Antenna Specifications (Recommendation)

NOTE:

1. RESET: Low Active, when EB-5662RE is accepted this single, EB-5662RE going to Hibernate
mode. If want EB-5662RE up, need input ON_OFF single.

2. TIMEPLUSE: One pulse per second output. When EB-5662RE is 3D Fixed, this pin will output
1uS Hi level pulse. If don’t use this, just NC.

3. WAKE_UP: EB-5662RE power on, WAKE_UP will output 1.8V.

4. ON_OFF: This pin is controlled EB-5662RE power on. If EB-5662RE want to EB-662 pin to pin
compactable, please ON_OFF connect to WAKE_UP. If don’t use this, just NC.

5. DR I2C interface: The I2C interface supports required sensor instruments such as gyros,
accelerometers, compasses or other sensors that can operate with an I2C bus. If don’t use
this, just NC.

6. VBAT: This is the battery backup power input for the SRAM and RTC when main power is
removed. VBAT is 2V ~ 3.5V.

7. EB-5662RE RF is has 3.3V external POWER to active ANTENNA use.
