1Introduction
This document describes SIM6216C hardware interface in great detail.
This document can help user to quickly understand SIM6216C interface specifications, electrical and
mechanical details. With the help of this document and other SIM6216C application notes, user guide,
users can use SIM6216C to design various applications quickly.
2SIM6216C Overview
SIM6216C supports CDMA2000 EV-DO rev. A which works on frequency of cellular 800MHz. User can
choose the module based on the wireless network configuration.
With a tiny configuration of 47*26*3mm, SIM6216C can meet almost all the space requirements in user
applications, such as Smart phone, PDA phone, industrial handhelds, machine-to-machine devices, vehicle
applications, etc..
There are 70 pins on SIM6216C, which provide most application interfaces for customers’ board.

zStorage temperature -40°C to +85°C
2.2 Operating Mode
The table below summarizes the various operating modes of SIM6216C.
Table 2: Overview of operating modes
Mode Function
CDMA2000
SLEEP
Module will automatically go into sleep mode if the conditions of sleep
mode are enabled and there is no on air and no hardware interrupt (such
as GPIO interrupt or data on serial/USB port).
In this case, the current consumption of module will be reduced to the
minimal level.
In sleep mode, the module can still receive paging message and SMS.
CDMA2000
IDLE
Software is active. Module is registered to the CDMA network, and
module is ready to communicate.
CDMA2000
TALK
Connection between two subscribers is in progress. In this case, the
power consumption depends on network settings
Normal
operation
EV-DO rev. A
TRANSFERD
ATA
There is EVDO data transfer in progress. In this case, power consumption
is related with network settings (e.g. power control level);
uplink/downlink data rates.
Power down
Normal power down by sending the AT command “AT+CPOF” or using the PWRKEY. The
power management unit shuts down the power supply for the baseband part of the module,
and only the power supply for the RTC is remained. Software is not active. The serial port
and USB are not accessible. Power supply (connected to VBAT) remains applied.
Minimum
functionality
mode
AT command “AT+CFUN” can be used to set the module to a minimum functionality mode
without removing the power supply. In this mode, the RF part of the module will not work or
the UIM card will not be accessible, or both RF part and UIM card will be closed, and the
serial port and USB are still accessible. The power consumption in this mode is lower than
