GXB5205
Initialization
The GXB5205 has a reset pin (Pin 6) and normally this pin should be left open. The GXB5205 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 [V]
VDD (Pin 8)
100ms or more
RST (Pin 6)
VDD/2
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
VDD [V]
VDD (Pin 8)
100µs or more
RST (Pin 6)
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
