USB2SER data sheet, rev. 0 functional description freescale semiconductor 8 each usb peripheral requires a unique vid/pid combination. vendor ids are assigned by the usb-if. it is possible to us the factory vid/pid combin ation, only if the product strings ar e not modified. in case that the st rings are changed, it is necessar y to get a different vid/pid combination. freescale, as a member of the usb-if, owns a vendor id and manages a database of product ids to be used in association with the vid. if a customer of freescale?s usb- enabled products is unable to procure thei r own vid, apply to use freescale?s vid in association with an assigned pid. in case the device loses powe r in the middle of a descriptors configuration pro cess, the default parameters will be loaded to ensure that the part remains functional in all cases. if this happens, the password to protect the device from further modifica tions will also be reset to the defaul t value which is ?ffffffffffffffff? 2 functional description the USB2SER is a usb2.0 full speed (12mb/ s) to the uart (rs232 or rs485) conver ter. this device integrates an on-chip full speed usb 2.0 compatible transceiver, the usb serial interface e ngine, and an on-chip 3.3 v voltage regulator to a uart communication. 2.1 crystal frequency auto-detection the USB2SER supports 2mhz, 4mhz, 6mhz, 8mhz, 12mh, and 16 mhz external crystals connected in a pierce oscillator configuration. figure 6. pierce oscillator 2.2 operating errors in case there is an error with the USB2SER, the de vice will generate a 2-bit gray sequence using the uart_led and usb_led . the following are the possible errors and the device expected behavior: ? for a pll issue (crystal outs ide the operating range) the gray sequence changes every 60 ms ? for a usb issue the seque nce changes every 200 ms 2.3 rs232 connections figure shows the recommended connections to an rs232 transceiver. when interf acing to an rs485 transceiver, the rs485_txen controls the transmitter enable signal.
functional description USB2SER data sheet, rev. 0 freescale semiconductor 9 figure 7. example schematic using an rs232 transceiver 2.4 uart baud rates baud rate is calculated by generating an internal divisor used to generate the clock for the uart communication module. the following calculation is used to estimate the real baud rate that will be generated by the device: where is the closest integer resulting from the division. after reset the device is automatically configured to communicate at 115,200 bps which is the maximum allowed value. 2.5 flow control operation the device works as a standard communicati on device class (cdc); to add flow control options to this class, the drivers are installed in the operating system to enable this functionality. when working without any flow control option, it is possible to generate an overflow condition, if the usb host does not reques t for the data received through th e serial interface fast enough. using any flow control option (h ardware or software) eliminates the overflow possibility. the following formula may be used to determine the amount of time without requesting data to generate the overflow condition: baudrate 24 000 000 ?? round 24 000 000 ?? desiredbaudrate 16 ? --------------------------------------------------------- ?? ?? 16 ? -------------------------------------------------------------------------------------------- - = round 24 000 000 ?? 24 000 000 ?? desiredbaudrate 16 ? --------------------------------------------------------- ?? ?? -------------------------------------------------------------- - =

USB2SER data sheet, rev. 0 electrical characteristics freescale semiconductor 14 appendix a electrical characteristics this chapter contains electri cal and timing specifications. a.1 parameter classification the electrical parameters shown in this supplement are guaranteed by various methods. to give the customer a better understanding, the followin g classification is used and the parameters are tagged accordingly in the tables where appropriate: note the above classifications are used in the column labeled c in applicable tables of this data sheet. a.2 absolute maximum ratings absolute maximum ratings are only stress ratings. functional oper ation at maximum is not guaranteed. stress beyond the limits specified in table a-2 may affect the device reliability or cause permanent damage to the device. for functional operating conditions, refer to the remaining tables in this section. this device contains circuitry protecting against damage due to hi gh static voltage or electrical fields. however, it is advis ed that normal precautions be taken to avoid application of any voltages higher than the maximum-rated voltages to this high- impedance circuit. reliability of operation is enhanced if unus ed inputs are tied to an approp riate logic voltage level (for instance, either v ss or v dd ). 1. input must be current limited to the value specified. to det ermine the value of the required current-limiting resistor, calc ulate resistance values for positive (vdd) and negative (vss) clamp vo ltages, then use the larger of the two resistance values. 2. all functional non-supply pins are intern ally clamped to vss and vdd. table a-1. parameter classifications p those parameters are guarantee d during production testing on each individual device. c those parameters are achieved by the design characterization by measuring a statistically relevant sample size across process variations. t those parameters are achieved by design char acterization on a small sample size from typical devices under typical conditions unless otherwise noted. all values shown in the typical column are within this category. d those parameters are derived mainly from simulations. table a-2. absolute maximum ratings rating symbol value unit supply voltage v dd 2.7 to 5.5 v input voltage v in ?0.3 to v dd + 0.3 v instantaneous maximum current single pin limit (applies to all port pins) 1, 2, 3 i d 25 ma maximum current into v dd i dd 120 ma storage temperature t stg ?55 to 150 ? c maximum junction temperature t j 150 ? c
