Functional description 7.1 Modes of operation The ISP1110 supports two modes of operation: * USB mode (3.3 V signaling) * UART mode (2.8 V signaling) Table 3 shows the definition of various operating modes. Table 3. Operating modes: definition VCC(I/O) VCC(UART) VCC(5V0) = VBUS UART_EN Mode Off X X X not defined On X off LOW isolate mode On on off HIGH UART mode On X on LOW USB mode Table 4 shows the pin status in various operating modes.

The DP and DM driver is powered by VREG. The USB function is compatible with the ISP1102 transceiver. When the ISP1110 is in USB mode, the TXD input pin is ignored and the RXD output pin is driven LOW. The ISP1110 is in USB mode when VCC(5V0) > VCC(5V0)th and UART_EN is LOW. VCC(I/O) must be on. A short description of the USB detection sequence is: 1. The phone is connected to the USB port of a powered PC. 2. The ISP1110 detects VBUS is above VCC(5V0)th. The ISP1110 enters USB mode and the Analog USB Transceiver (ATX) is powered by VREG. ISP1110_2 Product data sheet (c) NXP B.V. 2007. All rights reserved. Rev. 02 -- 19 March 2007 6 of 25 ISP1110 NXP Semiconductors USB transceiver with UART signaling 3. If the phone is switched off (VCC(I/O) is not present), then the DP and DM pins of the ISP1110 remain at high-impedance and the PC will not detect any device attachment. 4. If the phone is switched on (VCC(I/O) is present), then the ISP1110 will drive the VBUSDET pin to a HIGH level. 5. The phone processor detects that pin VBUSDET is HIGH. If the phone system software is ready for USB operation, the phone processor will assert pin SOFTCON. 6. The ISP1110 will enable the DP pull-up resistor (RPU(DP)). 7. The PC detects DP at the HIGH level and starts the USB full-speed enumeration. 8. The PC loads the driver for the phone, if enumeration is successful. For the flowchart, see Section 7.1.3. 7.1.2 UART mode When the ISP1110 is in UART mode, the DP and DM driver is powered by 2.8 V. The ISP1110 works as a level shifter between these pairs of pins: * From TXD (VCC(I/O) level) to DM (2.8 V level). * From DP (2.8 V level) to RXD (VCC(I/O) level). When the ISP1110 is in UART mode, the USB differential receiver is disabled. The SUSPEND and SOFTCON input pins are ignored. The RCV pin is driven LOW. The VP/VPO and VM/VMO pins are driven LOW, if OE_N is HIGH. The VP/VPO and VM/VMO pins are 3-state LOW, if OE_N is LOW. The ISP1110 is in UART mode when VCC(5V0) < VCC(5V0)th and pin UART_EN is HIGH. VCC(I/O) and VCC(UART) must be on. A short description of the UART detection sequence is: 1. The phone is switched on (VCC(I/O) is present). 2. If VBUS is off, the ISP1110 will drive VBUSDET to a LOW level. The ATX is powered by 2.8 V. 3. The ISP1110 will enter UART signaling mode, if UART_EN is HIGH. For the flowchart, see Section 7.1.3.

ISP1110 mode detection flowchart 7.1.4 Mode switching time When the USB cable is connected, the ISP1110 is in USB mode. When the USB cable is removed and the UART cable is connected, the ISP1110 may switch to UART mode as long as the VBUSDET output is LOW. On the other hand, if the UART cable is removed and the USB cable is connected, the ISP1110 can switch to USB mode. ISP1110_2 Product data sheet (c) NXP B.V. 2007. All rights reserved. Rev. 02 -- 19 March 2007 8 of 25 ISP1110 NXP Semiconductors USB transceiver with UART signaling UART mode cannot be enabled until the voltage on VCC(5V0) drops below the VBUSDET threshold (0.8 V to 4.0 V). Therefore, the time required to switch from USB mode to UART mode is determined by the RC discharge time on the VBUS line. Given that VCC(5V0) = 5.0 V, R = 100 k and C = 1 F, the discharge time is less than 200 ms (from 5 V to 0.8 V). Assume the detection of the UART cable connect or disconnect is very fast (within 1 ms), the total switching time from the USB cable removal to entering UART mode can be less than 200 ms. The total switching time from the UART cable removal to entering USB mode can be less than 200 ms. When VBUSDET becomes LOW, it is recommended that you wait for 50 ms before asserting UART_EN. This is because there is no hysteresis built for the VBUSDET threshold detector. The time between VBUSDET going HIGH and SOFTCON assertion is 0 ms to 100 ms, according to Universal Serial Bus Specification Rev. 2.0, Section 7.1.7.3. 7.2 Analog USB Transceiver (ATX) The ISP1110 ATX supports USB full-speed (12 Mbit/s) signaling. The ATX function is compatible with the ISP1102 transceiver. Table 5 shows the function of the ATX. Table 5.

[2] In suspend mode (SUSPEND = HIGH), the differential receiver is inactive and output RCV is always LOW. The resume signaling is detected through single-ended receivers VP/VPO and VM/VMO. Table 6.

Rev. 02 -- 19 March 2007 9 of 25 ISP1110 NXP Semiconductors USB transceiver with UART signaling 7.3 VBUS detector The VBUS detector provides voltage level detection on VBUS, if VBUS is connected to VCC(5V0). If VBUS is greater than VBUS valid threshold VCC(5V0)th, pin VBUSDET will output a HIGH level. Otherwise, pin VBUSDET will output a LOW level. The VBUS detector is powered by VCC(I/O). 7.4 DP pull-up resistor The internal DP pull-up resistor is connected between the VREG and DP pins, if pin SOFTCON is a HIGH level. The pull-up resistor is context variable, as described in document ECN_27%_Resistor. The variable pull-up resistor hardware is implemented here to meet the ECN_27%_Resistor specification. 7.5 DC-DC regulator In USB mode, when VCC(5V0) = 4.0 V to 5.5 V, the regulator will output 3.0 V to 3.6 V. In UART mode, when VCC(UART) = 2.7 V to 4.5 V, the regulator will output 2.35 V to 2.85 V. A 0.1 F capacitor is required to connect to the VREG pin. 7.6 Power selector When VBUSDET = HIGH, the regulator will be powered by VCC(5V0). When VBUSDET = LOW and UART_EN = HIGH, the regulator will be powered by VCC(UART). When VCC(I/O) is not connected, the DP and DM output will be in off-state. For proper operation, the VCC(I/O) voltage must not exceed VREG. ISP1110_2 Product data sheet (c) NXP B.V. 2007. All rights reserved.

Soldering This text provides a very brief insight into a complex technology. A more in-depth account of soldering ICs can be found in Application Note AN10365 "Surface mount reflow soldering description". ISP1110_2 Product data sheet (c) NXP B.V. 2007. All rights reserved. Rev. 02 -- 19 March 2007 18 of 25 ISP1110 NXP Semiconductors USB transceiver with UART signaling 15.1 Introduction to soldering Soldering is one of the most common methods through which packages are attached to Printed Circuit Boards (PCBs), to form electrical circuits. The soldered joint provides both the mechanical and the electrical connection. There is no single soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and Surface Mount Devices (SMDs) are mixed on one printed wiring board; however, it is not suitable for fine pitch SMDs. Reflow soldering is ideal for the small pitches and high densities that come with increased miniaturization. 15.2 Wave and reflow soldering Wave soldering is a joining technology in which the joints are made by solder coming from a standing wave of liquid solder. The wave soldering process is suitable for the following: * Through-hole components * Leaded or leadless SMDs, which are glued to the surface of the printed circuit board Not all SMDs can be wave soldered. Packages with solder balls, and some leadless packages which have solder lands underneath the body, cannot be wave soldered. Also, leaded SMDs with leads having a pitch smaller than ~0.6 mm cannot be wave soldered, due to an increased probability of bridging. The reflow soldering process involves applying solder paste to a board, followed by component placement and exposure to a temperature profile. Leaded packages, packages with solder balls, and leadless packages are all reflow solderable. Key characteristics in both wave and reflow soldering are: * * * * * * Board specifications, including the board finish, solder masks and vias Package footprints, including solder thieves and orientation The moisture sensitivity level of the packages Package placement Inspection and repair Lead-free soldering versus PbSn soldering 15.3 Wave soldering Key characteristics in wave soldering are: * Process issues, such as application of adhesive and flux, clinching of leads, board transport, the solder wave parameters, and the time during which components are exposed to the wave * Solder bath specifications, including temperature and impurities 15.4 Reflow soldering Key characteristics in reflow soldering are: * Lead-free versus SnPb soldering; note that a lead-free reflow process usually leads to higher minimum peak temperatures (see Figure 14) than a PbSn process, thus reducing the process window ISP1110_2 Product data sheet (c) NXP B.V. 2007. All rights reserved. Rev. 02 -- 19 March 2007 19 of 25 ISP1110 NXP Semiconductors USB transceiver with UART signaling * Solder paste printing issues including smearing, release, and adjusting the process window for a mix of large and small components on one board * Reflow temperature profile; this profile includes preheat, reflow (in which the board is heated to the peak temperature) and cooling down. It is imperative that the peak temperature is high enough for the solder to make reliable solder joints (a solder paste characteristic). In addition, the peak temperature must be low enough that the packages and/or boards are not damaged. The peak temperature of the package depends on package thickness and volume and is classified in accordance with Table 15 and 16 Table 15. SnPb eutectic process (from J-STD-020C) Package thickness (mm) Package reflow temperature (C) Volume (mm3) < 350 350 < 2.5 235 220 2.5 220 220 Table 16.
