Hardware Interface
A. UART interface:

11
The RC3000A-E provides an UART (universal asynchronous serial transmission)
port. It consists of a flexible 7-wire serial interface. The module is as the DCE
(Data Communication Equipment) and the client PC is as the DTE (Data Terminal
Equipment). AT commands are entered and serial communication is performed
through UART interface.
The application circuit is in the following figures.
Full modem
Null modem
If UART port is used in Null Modem, the pin “RI” can be used as an interrupt signal
to HOST. Normally it will keep high logic level until certain condition such as
receiving SMS, voice call (CSD, video) or URC reporting, then “RI” will change to

low logic level to inform the master (client PC). It will stay low until the master
clears the interrupt event with AT command.
If Full Modem is used to establish communication between devices, the pin “RI” is
another operation status. Initially it keeps high, when a voice call or CSD call comes,
the pin “RI” will change to low for about 5900ms, then it will return to high level for
100ms. It will repeat this procedure until this call is answered or hung up.
Note: RC3000A supports the communication rate: 300, 600, 1200, 2400, 4800, 9600,
19200, 38400, 57600, 115200, 230400, 460800, 921600, 3200000, 3686400,
4000000bps. Default rate is 115200bps.
B. Audio Interface:
RC3000A-E provides two analog signal outputs and one analog input. MIC1P/N is
used as microphone, EAR1P/N and SPK_P/N are used as audio output. Regarding
audio parameters configuration, please refer to the ATC manual.
There are three audio channels in RC3000A, including speaker output, receiver
output and microphone input. SPEAKER circuit in RC3000A is a Class-D amplifier.
Note: RC3000A has integrated MIC bias circuit. There is no need to pull the MIC1P
and MIC1N up to the external power, just connect it to microphone. MIC1P and
MIC1N must be differential lines.
Main audio parameters can be changed to satisfy users’ requirement. Here primary
register parameters and related description are listed. User can adjust them through
AT command.

C. USB Interface:
RC3000A-E module contains an USB interface. This interface is compliant with the
USB2.0 specification. The USB2.0 specification requires hosts such as the computer
to support all three USB speeds, namely low-speed (1.5Mbps), full-speed (12Mbps)
and high-speed (480Mbps). USB charging and USB-OTG is not supported.
Currently RC3000A supports the USB suspend and resume mechanism which can
help to save power. If not transaction is on USB bus, RC3000A will enter suspend
mode. When some events such as voice call or receiving SMS happen, RC3000A
will resume normal mode automatically.
Note: The RC3000A has two kinds of interface (UART and USB) to connect to host
CPU. USB interface is mapped to five virtual ports: “SIMTECH USB Modem”,
“SIMTECH NMEA Device”, “SIMTECH ATCOM Device”, “SIMTECH Diagnostics
interface” and “SIMTECH Wireless Ethernet Adapter”.

14
D. I2C Interface:
I2C is used to communicate with peripheral equipment and can be operated as either
a transmitter or receiver, depending on the device function. Use AT Commands
“AT+CRIIC and AT+CWIIC” to read/write register values of related peripheral
equipment connected with I2C interface.
Both SDA and SCL are bidirectional lines, connected to a positive supply via a pull-
up resistor respectively. When the bus is free, both lines are high.
For RC3000A, the data on the I2C bus can be transferred at rates up to 400kbps. The
number of peripheral devices connected to the bus is solely dependent on the bus
capacitance limit of 400pF. Note that PCB traces length and bending are in users’
control to minimize load capacitance.
Note:I2C_SDA and I2C_SCL have been pulled up with two 2.2kR resistors to 2.6V
level in module. So there is no need to pull them up in users’ application circuit.
E. SPI Interface:
SPI interface of RC3000A is master only. It provides a duplex, synchronous, serial
communication link with peripheral devices. Its operation voltage is 1.8V, with
clock rates up to 26 MHz.
F. GPIO Interface:
RC3000A provides a limited number of GPIO pins. All GPIOs can be configured as
inputs or ouputs. User can use AT Commands to read or write GPIOs status.
Note-1: If more GPIOs need to be used, users can configure GPIO on other multiple
function interfaces, such as PCM.
Note-2: The output driver current of GPIOs is 2mA.
G. PCM Interface:
RC3000A provides hardware PCM interface for external codec. The PCM interface
enables communication with an external codec to support hands-free applications.
RC3000A PCM interface can be used in two modes: the default mode is auxiliary
PCM (8 KHz long sync mode at 128 KHz PCM CLK). In short-sync (primary PCM)
mode, RC3000A can be a master or a slave. In long-sync (auxiliary PCM) mode,
RC3000A is always a master. RC3000A also supports 3 kinds of coding formats: 8
bits (υ-law or A-law) and 16 bits (linear).
Note: PCM interface is multiplexed from GPIO (default setting). The AT command
“AT+CPCM” is used to switch between PCM and GPIO functions.
ADC Interface:
RC3000A has a dedicated ADC that is available for digitizing analog signals such as
battery voltage and so on; it is on PIN 35 and PIN 36, namely ADC1 and ADC2.

15

User can introduces a signal in the ADC pin directly and use the AT command
“AT+CADC” to get the raw data which is between 0 and 4095. The data can be
transformed to any type such as voltage, temperature, etc.

16
Global Positioning System (GPS)
RC3000A merges GPS satellite and network information to provide a high-availability
solution that offers industry-leading accuracy and performance. This solution performs
well, even in very challenging environment conditions where conventional GPS receivers
fail, and provides a platform to enable wireless operators to address both location-based
services and emergency mandates.
Technical specification:
Tracking sensitivity -157dBm
Cold-start sensitivity -144dBm
Accuracy (Open Sky) <2m (CEP50)
TTFF (Open Sky) Hot start <1s Cold start 35s (good signal)/100s (weak signal)
Receiver Type 16-channel, GPS L1 Frequency (1575.42MHz), C/A Code
Update rate default 1 Hz
GPS data format NMEA-0183
GPS Current consumption (WCDMA/GSM Sleep mode) 100mA (Total supply current)
GPS antenna Passive/Active antenna
Note: Performance will vary depending on the environment, antenna type and signal conditions
and so on.
RC3000A supports both A-GPS and S-GPS, and then provides three operating modes: mobile-
assisted mode, mobile-based mode and standalone mode. A-GPS includes mobile-assisted and
mobile-based mode.
In mobile-assisted mode, when a request for position location is issued, available network
information is provided to the location server (e.g. Cell-ID) and assistance is requested from the
location server. The location server sends the assistance information to the handset. The
handset/mobile unit measures the GPS observables and provides the GPS measurements along
with available network data (that is appropriate for the given air interface technology) to the
location server. The location server then calculates the position location and returns results to
the requesting entity.
In mobile-based mode, the assistant data provided by the location server encompasses not only
the information required to assist the handset in measuring the satellite signals, but also the
information required to calculate the handset’s position. Therefore, rather than provide the GPS
measurements and available network data back to the location server, the mobile calculates the
location on the handset and passes the result to the requesting entity.
In standalone (autonomous) mode, the handset demodulates the data directly from the GPS
satellites. This mode has some reduced cold-start sensitivity, and a longer time to first fix as

17
compared to the assisted modes. However, it requires no server interaction and works out of
network coverage.
This combination of GPS measurements and available network information provides:
•High-sensitivity solution that works in all terrains: Indoor, outdoor, urban, and rural
•High availability that is enabled by using both satellite and network information
Therefore, while network solutions typically perform poorly in rural areas and areas of poor cell
geometry/density, and while unassisted, GPS-only solutions typically perform poorly indoors.
The RC3000A GPS solution provides optimal time to fix, accuracy, sensitivity, availability, and
reduced network utilization in both of these environments, depending on the given condition.
