UART interface:
11The 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 MODULE(DCE) Serial port TXD RXD RTS CTS DTR DCD RI MODULE(DCE) Serial port TXD RXD RTS CTS DTR DCD RI R R R R R R R MODULE(DCE) Serial port TXD RXD RTS CTS DTR DCD RI MODULE(DCE) Serial port TXD RXD RTS CTS DTR DCD RING GPIO R R Wake up host X X X X
12low 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”.
14D. 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.
15This ADC is 12 bit successive-approximation circuit, and electronic specification is shown in the following table. Electronic Characteristics: Specification Min Typ Max Unit Comments/Conditions Resolution 12 Bits Differential nonlinearity -4 +4 LSB Analog Vdd = ADC reference 2.4MHz sample rate Integral nonlinearity -8 +8 LSB Gain Error -2.5 +2.5 % Offset Error -4 +40 LSB Input Range GND 4.4V V Input serial resistance 2 kΩ Sample and hold switch resistance Input capacitance 53 pF Power-down to wakeup 9.6 19.2 µs 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.
16Global 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
17compared 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.

24Introduction to Modem Operation-The AT Command Set RC3000A modules are used to originate or answer telephone calls and establish links with other devices for the purpose of transmitting voice, data, or fax information between two locations. Please refer to the SIM900 AT Command Manual for complete AT command listings and information After installation, you will now be able to communicate with the modem and establish connections with remote devices. Controlling the modem functions is accomplished by using “AT” commands. These commands are used to instruct the modem to perform functions such as dialing or to answers calls. These commands are normally automatically issued by communication software. However for some applications, custom software may have to be written due to the absence of a normal operating system such as DOS or Windows. NOTE: The first AT command issued must be Upper Case AT. Subsequent AT commands can be either Upper Case or Lower Case. The modem will automatically accept and process “AT” commands at most standard DTE (Data Terminal Equipment) speeds and parity settings. For each command issued, the modem will respond with a result code informing you of the modem’s status. The format of a basic “AT” command and result code is as follows: AT <Command> <CR> OK AT = ATtention what follows is a command <Command> = any valid command <CR> = Carriage Return or Enter Key OK = Result code meaning: the modem has accepted the command AT Commands Samples A.
