3 2. Product Introduction UB603 is a GSM / GPRS wireless module that supports four channel networks such as GSM850/EGSM900/DCS1800/PCS1900. It also supports GPRS multi-slot class10 level. It integrates RF and baseband onto one single PCB. The modules finish the completed RF receiver/transmit, baseband processing and audio signal processing. Users just need to add very little external components to design the final wireless terminals. UB603 itself is only 40mm X 33mm X 3mm, with a single-sided PCB design. It connects to the product board through a 60-pin connector. Major function interface includes: power interface, serial communication interface, analog audio interface, SPI serial interface, LCD, 5X5 matrix keyboard interface, the standard SIM card interface, RF interface. Meanwhile UB603 has embedded TCP / IP protocol, supporst the AT command extensions. 2.1 List of Major feature Table: List of major features No Parameters Arguments 1 Power Supply DC: 3.3V-4.2V, typical: 4.0V 2 Frequency Bands GSM850/EGSM900/DCS1800/PCS GPRS GPRS mobile station: class B GPRS multi-slot Class: class 10 4 Network Protocol PPP, TCP/IP, USSD 5 Voice HR/FR/EFR Echo Suppression 6 Short Message MO/MT/CB, Support TEXT/PDU SMS Over GPRS 7 CSD Data Up to 14.4kbps 8 Power Consumption Off mode: <100uA Sleep mode: 2mA (average) Talk mode (GSM900, PCL=5): 300mA Data mode (GSM900, PCL=5, class 10): 400mA Peak: 2.0A 9 Temperature Normal operation: -20C to +55C 3 / 26

The range is 3.3V 4.2V. The Vnorm=4.0V peak current needs to be 2A. VRTC I/O When VBAT is powered, VTRC charges Vmax=3.3V the backup battery. When there is no Vmin=2.7V VBAT, VTRC supplies backup power to Vnorm=3.0V the module to keep real-time data. Inorm= 15uA VOUT O 2.8V output, used to supply power to Vmax=3.0V external circuits. At the same time, it Vmin=2.5V can be used to judge the ON/OFF Vnorm=2.8V status of the module. Imax=50mA GND Digital Ground ON/OFF Control PWR_ON I System Power off, active low.

During power cycle: LCD_DATA/NBOOT is low, the module will enter into firmware download mode. LCD_DATA/NBOOT is high, the module will enter into normal working mode. Wait until system boot, NBOOT can be configured for other purposes. 3.5 UART interface UB603 provides two UARTS, UART0 and UART1. UART0 support hardware flow control, and used to for AT command and download mode. The maximum support baud rate is bps. Figure 7: Diagram of UART0 12 / 26

It follows ISO of GSM Phase 2+, and also supports SIM toolkit release 99. The recommended SIM external circuits are shown in the following diagram. It s recommended to have ESD device close to SIM card, such as SMF05C (Semtech serial number). At the same time, add 100R resistor to SIM_RST, SIM_CLK, SIM_DATA lines. SIM_DATA should be pull to SIM_VCC through a 10K resistor. 17 / 26
