SIM5218E Hardware Design

2 Product concept

Designed for global market, SIM5218E is a quad-band GSM/GPRS/EDGE and UMTS engine that
works on frequencies of GSM 850MHz, EGSM 900 MHz, DCS 1800 MHz, PCS1900 MHz, and
WCDMA 2100M/1900M/900M. SIM5218E provides GPRS multi-slot class 12/class10/class 8
(optional) capability and EDGE, supports the GPRS coding schemes CS-1, CS-2, CS-3 and CS-4.
EDGE: 8 PSK, DTM (class A) multi-slot class 12, DL coding schemes: MCS1-9, UL coding
schemes: MCS1-9.SIM5218E also supports WCDMA HSDPA up to 7.2Mbps(Category 8) and
HSUPA up to 5.76Mbps(Category 6) respectively. SIM5218E supports antenna diversity at
WCDMA 2100M/1900M/900M. For further，SIM5218E is also integrated GPS.
*Note: SIM5218E only supports HSDPA, Category 6
HSDPA and HSUPA are used at the same time.
With a tiny configuration of 58.7mm × 28.77mm × 4.3 mm, SIM5218E can fit almost all the
space requirements in your applications, such as Smart phone, PDA phone and other mobile
devices.
The physical interface to the mobile application is made through a 70 pins board-to-board
connector, which provides all hardware interfaces between the module and customers' boards
except the RF antenna interface.
Serial port and USB 2.0(high speed) port can be alternatively used as data port.
USIM interface: support SIM cards: 3V & 1.8V
Power on/ff and reset signal
Backup RTC interface.
Six GPIOs: 1 for interrupt, 1 for flight mode, 1 for status LED, 2 for output control, 1
for input, also can be multiplex as a PCM interface.
Three audio channels include two microphones inputs and three audio outputs. This can
be easily configured by AT command.
A camera interface is provided.
An I2C interface is provided.
An ADC interface
A LDO power output
A 4 bit SD card interface
A PCM interface
The SIM5218E provides RF antenna interface with two alternatives: antenna connector and
antenna pad. The antenna connector is MURATA MM9329-2700. And customer's antenna can be
soldered to the antenna pad.
The SIM5218E is integrated with the TCP/IP protocol，Extended TCP/IP AT commands are
developed for customers to use the TCP/IP protocol easily, which is very useful for those data
