The only other requirements are voltage and RS232 receiving capability to capture the position outputs. The module is small and compact to fit into most applications. For the best results, the module should be placed with the antenna faced towards open sky to capture as much visible satellites as possible. -2- GXB5210 Pin Description Pin No. 1 2 3 4 5 6 7 8 9 10 Symbol TXD0 RXD0 1PPS BR1 BR0 RESET DGND VDD BATT AGND I/O O I O I I I Description UART(CH0) transmission data UART(CH0) reception data 1PPS output Baud rate setting 1 Baud rate setting 0 Hardware reset (Low active) Digital GND Power supply 3.4V Battery backup 2.8V Analog GND Operating Conditions Item Supply voltage Supply voltage ripple Backup battery voltage Input pin voltage Supply current: Acquisition Standby current Operating temperature Reception frequency, L1 CA code (25°C) Supply current: Tracking (25°C) Symbol VDD VCC Vbat VIN ICC ICC Istdby Topr FIN –40 2.6 –0.3 74 45 10 +25 1575.42 120 +85 2.8 Min. 3.1 Typ. 3.4 Max. 3.7 50 3.0 5.5 Unit V mVp-p V V mA mA μA °C MHz Operating Instructions 1. 2. 3. 4. 5. 6.

If 9600bps or 19200bps or 38400bps baud rate is set for port setting, it outputs 7 types of sentence: GPGGA, GPGSA, GPGSV, GPRMC, GPVTG, GPZDA, PSGSA as default. Moreover, if 4800bps baud rate is set, it outputs 4 types of sentences: GPGGA, GPGSA, GPGSV, GPRMC as default. -6- GXB5210 Initialization The GXB5210 has a reset pin (Pin 6) and normally this pin should be left open. The GXB5210 can perform the power-on reset operation only by turning on or off the power supply pin (Pin 8). In addition, when configuring the component in order to realize the reset from the system side during operation, connect the reset pin to the external circuit. The following setting enables the reset. 1. When turning the power on (Power-on reset) VDD VDD (Pin 8) VDD [V] 100ms or more VDD/2 RST (Pin 6) GND When applying the power supply to the power supply pin (Pin 8), set the reset pin (Pin 6) Low in advance, and set it High 100ms after power-on. 2. Initialization during operation VDD (Pin 8) VDD RST (Pin 6) VDD [V] 100µs or more VDD/2 GND When performing the reset while the reset pin (Pin 6) is High, keep it Low for 100μs or more before setting High. NMEA Message Output Timing NMEA messages are output within 1s after the 1PPS pulse. -7- GXB5210 t+1 t+2 t+3 t+4 t+5 t+6 T 1PPS t+1 t+2 t+3 t+4 t+5 t+6 NMEA -8- GXB5210 1PPS Output The 1PPS output provides a timing pulse synchronized to GPS time once a valid fix is available. The figure below shows the behavior of the 1PPS output signal after reset. For a period of 160μs after reset, the 1PPS signal outputs the system clock. The actual 1PPS signal is activated at 500ms after reset. Reset 1+ ECLKOUT (1PPS) 500ms 1PPS signal output occurs 500ms after reset Expansion Reset 1+ 160µs ECLKOUT (1PPS) CPU clock exists for 160µs after reset Expansion Reset 1+ ECLKOUT (1PPS) 145ns (6.90MHz) -9- GXB5210 Backup Mode The backup mode is established by setting all inputs Low except for B.U. (Vbat: 2.6 to 3.0V). In this mode, the low power consumption can be achieved by stopping all oscillators except for RTC oscillator. Although all registers are initialized, the SRAM for both of Ephemeris data and Almanac data in backup area are held. Command Specifications The GXB5210 modules have a command format, NMEA-0183 version 3.01. A list of the supported UART interface is as follows.
