DESCRIPTION The SP3203E provides a RS-232 transceiver solution for portable and hand-held applications such as palmtops, PDA's and cell phones. The SP3203E uses an internal highefficiency, charge-pump that requires only 0.1F capacitors during 3.3V operation. This charge pump and Sipex's driver architecture allow the SP3203E to deliver compliant RS-232 performance from a single power supply ranging from +3.0V to +5.5V. The SP3203E is a 3-driver/2-receiver device, with a unique VL pin to program the TTL input and output logic levels to allow interoperation in mixed-logic voltage systems such as PDA's and cell phones. Receiver outputs will not exceed VL for VOH and transmitter input logic levels are scaled by the magnitude of the VL input.

DESCRIPTION The SP3203E is a 3-driver/2-receiver device that can be operated as a full duplex, RS-232 serial transceiver with the 3rd driver acting as a control line allowing a Ring Indicator (RI) signal to alert the UART on the PC. This transceiver meet the EIA/TIA-232 and ITUT V.28/V.24 communication protocols and can be implemented in battery-powered, portable, or hand-held applications such as notebook or palmtop computers, PDA's and cell phones. The SP3203E devices feature Sipex's proprietary and patented (U.S.#5,306,954) on-board charge pump circuitry that generates 5.5V RS-232 voltage levels from a single +3.0V to +5.5V power supply. The SP3203E devices can operate at a minimum data range of 250kbps, driving a single driver. The SP3203E is a 3-driver/2-receiver device. THEORY OF OPERATION The SP3203E contains four basic circuit blocks: 1. drivers, 2. receivers, 3. a Sipex proprietary charge pump and 4. VL circuitry. Drivers The drivers are inverting level transmitters that convert TTL or CMOS logic levels to 5.0V EIA/ TIA-232 levels with an inverted sense relative to the input logic levels. Typically, the RS-232 output voltage swing is +5.4V with no load and +5V minimum fully loaded. The driver outputs are protected against infinite short-circuits to ground without degradation in reliability. These drivers comply with the EIA-TIA-232F and all previous RS-232 versions. The driver output stages are turned off (High Impedance) when the device is in shutdown mode. The drivers typically can operate at a data rate of 250Kbps. The drivers can guarantee a data rate of 120Kbps fully loaded with 3K in parallel with 1000pF, ensuring compatibility with PC-to-PC communication software.
The slew rate of the driver output is internally limited to a maximum of 30V/s in order to meet the EIA standards (EIA RS-232D 2.1.7, Paragraph 5). The transition of the loaded output from HIGH to LOW also meets the monotonicity requirements of the standard. The SP3203E driver can maintain high data rates up to 250Kbps with a single driver loaded. Figure 9 shows a loopback test circuit used to test the RS-232 Drivers. Figure 10 shows the test results of the loopback circuit with all three drivers active at 120Kbps with typical RS-232 loads in parallel with 1000pF capacitors. Figure 11 shows the test results where one driver was active at 250Kbps and all three drivers loaded with an RS-232 receiver in parallel with a 1000pF capacitor. The transmitter inputs do not have pull-up resistors. Connect unused inputs to ground or VL Receivers The receivers convert 5.0V EIA/TIA-232 levels to TTL or CMOS logic output levels. Receivers are disabled when in shutdown. The truth table logic of the SP3203E driver and receiver outputs can be found in Table 1. Since receiver input is usually from a transmission line where long cable lengths and system interference can degrade the signal, the inputs have a typical hysteresis margin of 500mV. This ensures that the receiver is immune to noisy transmission lines. Should an input be left unconnected, an internal 5K pulldown resistor to ground will commit the output of the receiver to a HIGH state. Charge Pump The charge pump is a Sipex-patented design (U.S. #5,306,954) and uses a unique approach compared to older less-efficient designs. The charge pump still requires four external capacitors, but uses a four-phase voltage shifting technique to attain symmetrical 5.5V power supplies. The internal power supply

consists of a regulated dual charge pump that provides output voltages of 5.5V regardless of the input voltage (VCC) over the +3.0V to +5.5V range. This is important to maintain compliant RS-232 levels regardless of power supply fluctuations. The charge pump operates in a discontinuous mode using an internal oscillator. If the output voltages are less than a of 5.5V, the charge pump is enabled. If the output voltages exceed a of 5.5V, the charge pump is disabled. This oscillator controls the four phases of the voltage shifting (Figure 12). A description of each phase follows. VSS Charge Storage-Phase 1(Figure 13) During this phase of the clock cycle, the positive side of capacitors C1 and C2 are initially charged to VCC. Cl+ is then switched to GND and the charge in C1- is transferred to C2-. Since C2+ is connected to VCC, the voltage potential across capacitor C2 is now 2 times VCC.

VSS Transfer-Phase 2 (Figure 14) Phase two of the clock connects the negative terminal of C2 to the VSS storage capacitor and the positive terminal of C2 to GND. This transfers a negative generated voltage to C3. This generated voltage is regulated to a minimum voltage of -5.5V. Simultaneous with the transfer of the voltage to C3, the positive side of capacitor C1 is switched to VCC and the negative side is connected to GND.

duces -VCC in the negative terminal of C1, which is applied to the negative side of capacitor C2. Since C2+ is at VCC, the voltage potential across C2 is 2 times VCC. VDD Transfer-Phase 4 (Figure 16) The fourth phase of the clock connects the negative terminal of C2 to GND, and transfers this positive generated voltage across C2 to C4, the VDD storage capacitor. This voltage is regulated to +5.5V. At this voltage, the internal oscillator is disabled. Simultaneous with the transfer of the voltage to C4, positive side of capacitor C1 is switched to VCC and the negative side is connected to GND, allowing the charge pump cycle to begin again. The charge pump cycle will continue as long as the operational conditions for the internal oscillator are present. Since both V+ and V- are separately generated from VCC, in a no-load condition, V+ and V- will be symmetrical. Older charge pump approaches that generate V- from V+ will show a decrease in the magnitude of V- compared to V+ due to the inherent ineffiencies in the design. The clock rate for the charge pump is typically operates at 250kHz. The external capacitors are usually 0.1F with a 16V breakdown voltage rating. VL Supply Level Current RS-232 serial tranceivers are designed with fixed 5V or 3.3V TTL input/output voltages levels. The VL function in the SP3203E allows the end user to set the TTL input/output voltage levels independent of VCC. By connecting VL to the main logic bus of system, the TTL input/ output limits and threshold are reset to interface with the on board low voltage logic circuity.

ESD TOLERANCE The SP3203E incorporates ruggedized ESD cells on all driver output and receiver input pins. The improved ESD tolerance is at least 15kV without damage nor latch-up. There are different methods of ESD testing applied:
a) MIL-STD-883, Method 3015.7 b) IEC1000-4-2 Air-Discharge c) IEC1000-4-2 Direct Contact
two methods within IEC1000-4-2, the Air Discharge method and the Contact Discharge method. With the Air Discharge Method, an ESD voltage is applied to the equipment under test (EUT) through air. This simulates an electrically charged person ready to connect a cable onto the rear of the system only to find an unpleasant zap just before the person touches the back panel. The high energy potential on the person discharges through an arcing path to the rear panel of the system before he or she even touches the system. This energy, whether discharged directly or through air, is predominantly a function of the discharge current rather than the discharge voltage. Variables with an air discharge such as approach speed of the object carrying the ESD potential to the system and humidity will tend to change the discharge current. For example, the rise time of the discharge current varies with the approach speed. The Contact Discharge Method applies the ESD current directly to the EUT. This method was devised to reduce the unpredictability of the ESD arc. The discharge current rise time is constant since the energy is directly transferred without the air-gap arc. In situations such as hand held systems, the ESD charge can be directly discharged to the equipment from a person already holding the equipment. The current is transferred on to the keypad or the serial port of the equipment directly and then travels through the PCB and finally to the IC. The circuit model in Figures 18 and 19 represent the typical ESD testing circuit used for all three methods. The CS is initially charged with the DC
RS RS
The Human Body Model has been the generally accepted ESD testing method for semiconductors. This method is also specified in MIL-STD-883, Method 3015.7 for ESD testing. The premise of this ESD test is to simulate the human body's potential to store electro-static energy and discharge it to an integrated circuit. The simulation is performed by using a test model as shown in Figure 18. This method will test the IC's capability to withstand an ESD transient during normal handling such as in manufacturing areas where the ICs tend to be handled frequently. The IEC-1000-4-2, formerly IEC801-2, is generally used for testing ESD on equipment and systems. For system manufacturers, they must guarantee a certain amount of ESD protection since the system itself is exposed to the outside environment and human presence. The premise with IEC1000-4-2 is that the system is required to withstand an amount of static electricity when ESD is applied to points and surfaces of the equipment that are accessible to personnel during normal usage. The transceiver IC receives most of the ESD current when the ESD source is applied to the connector pins. The test circuit for IEC1000-4-2 is shown on Figure 19. There are

power supply when the first switch (SW1) is on. Now that the capacitor is charged, the second switch (SW2) is on while SW1 switches off. The voltage stored in the capacitor is then applied through RS, the current limiting resistor, onto the device under test (DUT). In ESD tests, the SW2 switch is pulsed so that the device under test receives a duration of voltage. For the Human Body Model, the current limiting resistor (RS) and the source capacitor (CS) are 1.5kW an 100pF, respectively. For IEC-1000-42, the current limiting resistor (RS) and the source capacitor (CS) are 330W an 150pF, respectively. The higher CS value and lower RS value in the IEC1000-4-2 model are more stringent than the Human Body Model. The larger storage capacitor injects a higher voltage to the test point when SW2 is switched on. The lower current limiting resistor increases the current charge onto the test point.
