Interfaces

Module interface

Surface mount device with solderable connection pads (SMT application

interface). Land grid array (LGA) technology ensures high solder joint reli-

ability and allows the use of an optional module mounting socket.

For more information on how to integrate SMT modules see also

[3]

. This

application note comprises chapters on module mounting and application

layout issues as well as on SMT application development equipment.

2 serial interfaces

ASC0:

•

8-wire modem interface with status and control lines, unbalanced, asyn-
chronous

•

Default baud rate: 115,200 baud

•

Adjustable baud rates: 1,200 to 3,686,400

•

Supports RTS0/CTS0 hardware flow control.

•

Indication of incoming data/SMS on RING0 (can be used to wake up
host from power down modes)

ASC1 (shared with GPIO lines):

•

4-wire, unbalanced asynchronous interface

•

Default baud rate: 115,200 baud

•

Adjustable baud rates: 1,200 to 3,686,400bps

•

Supports RTS1/CTS1 hardware flow control

UICC interface

Supported SIM/USIM cards: 3V, 1.8V

Embedded UICC

Module is hardware prepared for an embedded UICC (MIM)

GPIO interface

20 pads of the application interface programmable as GPIO pads (17) or

GPO pads (3):

GP(I)Os can be configured as ASC0 andASC1

Programming is done via AT commands

Antenna interface pad

Ω

LTE antenna

Power on/off, Reset

Power on/off

Switch-on by hardware signal ON

Switch-off by AT command

Automatic switch-off in case of critical temperature and voltage conditions

Reset

Orderly shutdown and reset by AT command

Evaluation kit

Evaluation module

EMS31-US module soldered onto a dedicated PCB that can be connected

to an adapter in order to be mounted onto the DSB75.

DSB75

DSB75 Development Support Board designed to test and type approve

Gemalto M2M modules and provide a sample configuration for application

engineering. A special adapter is required to connect the EMS31-US evalu-

ation module to the DSB75.
