SIM5218E Hardware Design

3 Application interface

All hardware interfaces except RF interface that connects SIM5218E to the customers' cellular
application platform is through a 70-pin 0.4mm pitch board-to-board connector. Figure 1 is
SIM5218E system overview. Figure 2 is SIM5218E block diagram. Sub-interfaces included in this
board-to-board connector are described in detail in following chapters:
Power supply
USB interface
Serial interface
Analog audio interfaces
SIM interface
GPIO
ADC
LDO Power output
PCM interface
MMC/SD interface
Camera interface
RTC
I2C interface
Electrical and mechanical characteristics of the board-to-board connector are specified in
Chapter 6. There we also order information for mating connectors.
