4.2. SIM interface

4.2.1. SIM IC

This optional chip located on the development kit can emulate a SIM card. It has the following specification.

3GPP TS 51.011, 51.014, 43.019, 23.040, 23.140

3GPP TS 23.048

3GPP TS 22.048

ETSI TS 102 221, 102 222

ISO / IEC 7816

The SIM IC is compatible with the ISO 7816-3 IC standard required by the GSM 11.11 Phase 2+ standard.

The SIM IC interface insures the power on (SIMVCC) of the SIM Chip and the communication with it through a data signal (SIMDAT), a clock signal (SIMCLK) and a reset signal (SIMRST).

Switch S601 to position "2" to use this SIM.

4.2.2. SIM CARD

The SIM Card interface is compatible with the ISO 7816-3 IC card standard required by the GSM 11.11 Phase 2+ standard. The module also supports Release 99 of the SIM Toolkit recommendation and supports a Fixed Dialling Number directory.

The SIM Card interface insures the detection (SIMCD), the power on (SIMVCC) of the SIM Card and the communication with it through a data signal (SIMDAT), a clock signal (SIMCLK) and a reset signal (SIMRST).

Switch S601 to position "1" to use this SIM card.

The jumper TB704 connects the SIM card presence detection to the GPIO2 (IO2)

4.5. Analog audio interface

The HILO can manage an external microphone (MIC) in single mode and external speaker (32 ohms HSET_N/HSET_P) in differential mode.

Thus, one receiver and one microphone can be connected to the module with the following characteristics (see SAGEM references in the document “URD1 5635.1 007 70230 - Hilo application note”):

Receiver 32 ohms up to 120 ohms The microphone can be supplied using the internal HILO bias supply (recommended but

not mandatory) or any other external bias system compliant with selected microphone within the HILO inputs limits.

The Development Kit includes all protections which are advised in the document “ URD1 5635.1 007 70230 - Hilo application note ”.

4.9.4. GSM Antenna

The two antennas connectors can be connected to the HILO module either via a mini coaxial connector or via 2 spring contacts.

When the spring contact E101 and E102 are chosen, simply plug the Hilo module and connect an antenna to P102.

When the mini coaxial cable is used : connect the cable to P104 on one side and to the Hilo module coaxial antenna out on the other side. Then connect an antenna to P103. In this configuration, if the Hilo development kit is used to make some accurate radio performances measurements, please add a tape on the E101 and E102 to avoid to create a "stub" effect resulting in radio performance losses.

4.9.5. Auto power-on The HILO can power on automatically on the development board when a jumper is set on

TB301 between position 4 and 3, low level active PWON is therefore set to ground level.

4.9.6. Hardware reset.

The Hilo module can control an external reset device via the GPIO3 (IO3).

Connect the jumper TB102 to enable the connection between the chip and the GPIO.

It can also be done manually by using S100 to provoke a hardware reset.

In both cases, a jumper must be set in TB301 between position 4 and 3. This pull-down PWON signal and then enable an auto power-on whenever the power supply is available.
