SP3239E Typical Operating Circuit Rev.4/08/02 SP3239E Intelligent +3.0V to +5.5V RS-232 Transceivers 6 (c) Copyright 2002 Sipex Corporation DESCRIPTION The SP3238E device is an ideal choice for power sensitive designs. The SP3239E device meets the EIA/TIA-232 and ITU-T V.28/V.24 communication protocols and can be implemented in battery-powered, portable, or hand-held applications such as notebook or palmtop computers. The SP3239E device features 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 SP3239E device can operate at a data rate of 250kbps fully loaded. THEORY OF OPERATION The SP3239E device is made up of three basic circuit blocks: 1. Drivers, 2. Receivers, and 3. the Sipex proprietary charge pump. 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. Unused driver inputs should be connected to VCC or GND. The SP3239E is a 5-driver/3-receiver device, ideal for portable or hand-held applications. The SP3239E includes one complementary always-active receiver that can monitor an external device (such as a modem) in shutdown. This aids in protecting the UART or serial controller IC by preventing forward biasing of the protection diodes where VCC may be disconnected. The drivers can guarantee a data rate of 250kbps fully loaded with 3k in parallel with 1000pF, ensuring compatibility with PC-to-PC communication software.

The transition of the loaded output from HIGH to LOW also meets the monotonicity requirements of the standard. 0.1F RS-232 OUTPUTS 16 R1OUT TxD R1IN 8 21 R1OUT Figure 7 shows a loopback test circuit used to test the RS-232 Drivers. Figure 8 shows the test results of the loopback circuit with all five drivers active at 120kbps with typical RS-232 loads in parallel with 1000pF capacitors. Figure 6 shows the test results where one driver was active at 250kbps and all five drivers loaded with an RS232 receiver in parallel with a 1000pF capacitor.

R1OUT is an extra output that remains active and monitors activity while the other receiver outputs are forced into high impedance. This allows Ring Indicator (RI) from a peripheral to be monitored without forward biasing the TTL/ CMOS inputs of the other devices connected to the receiver outputs.

This ensures that the receiver is virtually 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. Figure 7. Loopback Test Circuit for RS-232 Driver Data Transmission Rates 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 Figure 8. Loopback Test Circuit Result at 120kbps (All Drivers Fully Loaded) Rev.4/08/02 + Figure 9. Loopback Test Circuit result at 250kbps (All Drivers Fully Loaded) SP3239E Intelligent +3.0V to +5.5V RS-232 Transceivers 8 (c) Copyright 2002 Sipex Corporation provides output voltages 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. Phase 4 (Figure 14) -- VDD transfer -- 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, the 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. The charge pump operates in a discontinuous mode using an internal oscillator. If the output voltages are less than a magnitude of 5.5V, the charge pump is enabled. If the output voltages exceed a magnitude 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. Phase 1 (Figure 10) -- VSS charge storage -- 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. 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 inefficiencies in the design. The clock rate for the charge pump typically operates at 500kHz. The external capacitors can be as low as 0.1F with a 16V breakdown voltage rating. Phase 2 (Figure 11) -- VSS transfer -- 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 C 3 . 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. Phase 3 (Figure 13) -- VDD charge storage -- The third phase of the clock is identical to the first phase -- the charge transferred in C1 produces -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.

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 20. There are two methods within IEC1000-4-2, the Air Discharge method and the Contact Discharge method. ESD TOLERANCE The SP3239E device incorporates ruggedized ESD cells on all driver output and receiver input pins. The ESD structure is improved over our previous family for more rugged applications and environments sensitive to electrostatic discharges and associated transients. The improved ESD tolerance is at least +15kV without damage nor latch-up. 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. 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 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 16. 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 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 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 RSS RC C SW2 SW2 SW1 SW1 CSS DC Power Source Device Under Test Figure 16.

Figure 17. ESD Test Circuit for IEC1000-4-2 i The circuit model in Figures 16 and 17 represent the typical ESD testing circuit used for all three methods. The CS is initially charged with the DC 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. 30A 15A 0A 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. t=0ns t=30ns t Figure 18. ESD Test Waveform for IEC1000-4-2 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.
