URD1 – OTL 5696.1– 022 / 72740 Edition 0.4 HILONC- 3GPS APPLICATION NOTE
3. Functional Integration
Advancements in silicon technology have brought about concurrent functionality improvements that allow lower
power consumption. The HILONC-3GPS module with 116 pin LGA is a very compact design with dimensions of
only 28.5 x 34 x 2.35 mm and weighing less than 7 grams.
 All digital I/Os among the 116 pin LGA are within the 1.8V domain suitable for most systems with the
exception of SIM I/O's, which can also be in the 3V domain depending on SIM-card use, and SDIOs which are
in the 2.85V domain.
 Analog I/Os occupy the following power domains:
·
VSIM

SIM I/Os are in the 1.8V or 3V domain
·
VBACKUP

3V domain
·
VGPIO

2.85V domain
·
VBAT

from 3.4V to 4.2V. 3.7V is normal.
·
VUSB

5V
·
ADC

2.2V
·
Antenna

RF power amplifier is in the VBAT domain
 Do not power on the module I/O with a voltage over the specified limits. This could cause damage to the
module.
 In order to achieve accurate audio performance from customer products it is necessary to have a basic
competency in acoustic engineering.
 In order to achieve accurate radio performance from customer products it is necessary to have a basic
competency in radio engineering.
