UMTS/HSDPA Module Series UC15 Hardware Design Figure 3: UART Sleep Application The RI of module is used to wake up the processor, and AP_READY will detect the sleep state of processor (can be configured to high level or low level detection). You should pay attention to the level match shown in dotted line between module and processor. Drive DTR to low level will wake up the module. 3.5.1.2.
UMTS/HSDPA Module Series UC15 Hardware Design When the processor’s USB bus returns to resume state, the module will be woken up. 3.5.1.3. USB Application without Suspend Function If application processor communicates with module via USB interface, and processor does not support USB suspend function, you should disconnect USB_VBUS with additional control circuit to let the module enter into sleep mode. Execute AT command AT+QSCLK=1 to enable the sleep mode. Disconnect USB_VBUS.
UMTS/HSDPA Module Series UC15 Hardware Design AT+CFUN=4: Disable RF function (airplane mode). All AT commands related to RF function are not accessible. For detailed information about command AT+CFUN, please refer to document [1]. 3.6. Power Supply 3.6.1. Power Supply Pins UC15 provides four VBAT pins to connect with the external power supply. There are two separate voltage domains for VBAT. VBAT_RF with two pads for module RF. VBAT_BB with two pads for module baseband.
UMTS/HSDPA Module Series UC15 Hardware Design Figure 6: Star Structure of the Power Supply Please pay special attention to the power supply design for applications. Make sure the input voltage will never drop below 3.3V. If the voltage drops below 3.3V, the module will turn off automatically. The PCB traces from the VBAT pins to the power source must be wide enough to ensure that there is not too much voltage drop occurs in the transmitting procedure.
UMTS/HSDPA Module Series UC15 Hardware Design 3.6.4. Monitor the Power Supply You can use the AT+CBC command to monitor the VBAT_BB voltage value. For more details, please refer to document [1]. 3.6.5. VDD_EXT UC15 has a LDO power output, named VDD_EXT. The VDD_EXT is available and output voltage is 2.6V by default, rated at 100mA. The following table shows electrical characteristics of VDD_EXT. Table 7: Electrical Characteristics of VDD_EXT Symbol Description Min. Typ. Max.
UMTS/HSDPA Module Series UC15 Hardware Design When UC15 is in power down mode, it can be turned on to normal mode by driving the PWRKEY pin to low level at least 0.1s. It is recommended to use an open collector driver to control the PWRKEY. You can monitor the level of the STATUS pin to judge whether the module is turned on or not. After STATUS pin outputting a high level, module is turned on. A simple reference circuit is illustrated in the following figure.
UMTS/HSDPA Module Series UC15 Hardware Design The turn on scenarios is illustrated as the following figure. Figure 10: Timing of Turning on Module NOTE ① Make sure that VBAT is stable before pulling down PWRKEY pin. The time between them is recommended to be more than 0.03s. 3.7.2. Turn off Module The following procedures can be used to turn off the module: Normal power down procedure: Turn off the module by PWRKEY pin. Normal power down procedure: Turn off the module by command AT+QPOWD.
UMTS/HSDPA Module Series UC15 Hardware Design Figure 11: Timing of Turning off Module During power-down procedure, module will send out URC “NORMAL POWER DOWN” via URC port first, then log off network and save important data. After logging off, module sends out “POWERED DOWN” and shuts down the internal power supply. The power on VBAT pins are not allowed to be switched off before the URC “POWERED DOWN” is output to avoid data loss.
UMTS/HSDPA Module Series UC15 Hardware Design If the voltage < 3.2V, the following URC will be presented: +QIND: “vbatt”,-2 If the voltage > 4.35V, the following URC will be presented: +QIND: “vbatt”,2 NOTE The value of voltage threshold can be revised by AT command AT+QCFG=“vbatt”, refer to document [1] for details. 3.8. Reset the Module The RESET_N can be used to reset the module. Table 9: RESET_N Pin Description Pin Name RESET_N Pin No.
UMTS/HSDPA Module Series UC15 Hardware Design The reset scenario is illustrated as the following figure. Figure 13: Timing of Resetting Module NOTE The low-level pulse through the RESET_N pin cannot last for more than 0.2s, otherwise the module will be powered off. 3.9.

UMTS/HSDPA Module Series UC15 Hardware Design 3.9.2. UART Application The reference design of 3.3V level match is shown as below. When the peripheral MCU/ARM system is 3V, the divider resistor should be changed from 3.6K to 6.8K. Figure 17: 3.3V Level Match Circuit The reference design of 5V level match is shown as below. The construction of dotted line can refer to the construction of solid line. Please pay attention to direction of connection.
UMTS/HSDPA Module Series UC15 Hardware Design The following figure is an example of connection between module and PC. A RS232 level shifter IC or circuit must be inserted between module and PC, since UART interface do not support the RS232 level, while support the CMOS level only. Figure 19: RS232 Level Shift Circuit NOTES 1. 2. Rising edge on DTR will let the module exit from the data mode by default. It can be disabled by command. Refer to document [1] about AT&D and AT&V for details.

UMTS/HSDPA Module Series UC15 Hardware Design The severity degree of the RF interference in the voice channel during GSM transmitting period largely depends on the application design. In some cases, GSM850/EGSM900 TDD noise is more severe; while in other cases, DCS1800/PCS1900 TDD noise is more obvious. Therefore, customer can have a choice based on test results. Sometimes, even no RF filtering capacitor is required. The capacitor which is used for filtering out RF noise should be close to audio interface.

UMTS/HSDPA Module Series UC15 Hardware Design 7 Storage and Manufacturing 7.1. Storage UC15 is stored in the vacuum-sealed bag. The restriction of storage condition is shown as below. Shelf life in sealed bag is 12 months at < 40ºC/90%RH. After this bag is opened, devices that will be subjected to reflow solder or other high temperature process must be: Mounted within 72 hours at factory conditions of ≤ 30ºC/60%RH. Stored at < 10% RH.
UMTS/HSDPA Module Series UC15 Hardware Design It is suggested that peak reflow temperature is 235~245ºC (for SnAg3.0Cu0.5 alloy). Absolute max reflow temperature is 260ºC. To avoid damage to the module when it was repeatedly heated, it is suggested that the module should be mounted after the first panel has been reflowed. The following picture is the actual diagram which we have operated. Figure 48: Reflow Soldering Profile 7.3. Packaging UC15 is packaged in the tap and reel carriers. One reel is 12.

UMTS/HSDPA Module Series UC15 Hardware Design 10 Appendix C GPRS Multi-slot Class Twenty-nine classes of GPRS multi-slot modes are defined for MS in GPRS specification. Multi-slot classes are product dependant, and determine the maximum achievable data rates in both the uplink and downlink directions. Written as 3+1 or 2+2, the first number indicates the amount of downlink timeslots, while the second number indicates the amount of uplink timeslots.
