Model Selection Table DESCRIPTION The SP207E-SP213E are enhanced transceivers intended for use in RS-232 and V.28 serial communication. These devices feature very low power consumption and single-supply operation making them ideal for space-constrained applications. Exar-patented (5,306,954) on-board charge pump circuitry generates fully compliant RS-232 voltage levels using small and inexpensive 0.1F charge pump capacitors. External +12V and -12V supplies are not required. The SP211E and SP213E feature a low-power shutdown mode, which reduces power supply drain to 1A. SP213E includes two receivers that remain active during shutdown to monitor for signal activity. The SP207E-SP213E devices are pin-to-pin compatible with our previous SP207, SP208, SP211 and SP213 as well as industry-standard competitor devices. Driver output and receiver input pins are protected against ESD to over 15kV for both Human Body Model and IEC1000-4-2 Air Discharge test methods. Data rates of over 120kbps are guaranteed with 230kbps typical, making them compatible with high speed modems and PC remote-access applications. Receivers also incorporate hysteresis for clean reception of slow moving signals.

All of these devices feature low-power CMOS construction and EXAR-proprietary on-board charge pump circuitry to generate RS-232 signal-voltages, making them ideal for applications where +9V and -9V supplies are not available. The highly efficient charge pump is optimized to use small and inexpensive 0.1F charge pump capacitors, saving board space and reducing overall circuit cost. Transmitter/Drivers The drivers are single-ended inverting transmitters, which accept either TTL or CMOS inputs and output the RS-232 signals with an inverted sense relative to the input logic levels. Should the input of the driver be left open, an internal pullup to VCC forces the input high, thus committing the output to a logic-1 (MARK) state. The slew rate of the transmitter output is internally limited to a maximum of 30V/s in order to meet the EIA/RS-232 and ITU V.28 standards. The transition of the output from high to low also meets the monotonicity requirements of the standard even when loaded. Driver output voltage swing is 7V (typical) with no load, and 5V or greater at maximum load. The transmitter outputs are protected against infinite short-circuits to ground without degradation in reliability. Each device provides a different driver/ receiver combination to match standard application requirements. The SP207E is a 5-driver, 3-receiver device, ideal for DCE applications such as modems, printers or other peripherals. SP208E is a 4-driver/4receiver device, ideal for providing handshaking signals in V.35 applications or other general-purpose serial communications. The SP211E and SP213E are each 3-driver, 5-receiver devices ideal for DTE serial ports on a PC or other data-terminal equipment. The drivers of the SP211E, and SP213E can be tri-stated by using the SHUTDOWN function. In this "power-off" state the charge pump is turned off and VCC current drops to 1A typical. Driver output impedance will remain greater than 300, satisfying the RS-232 and V.28 specifications. For SP211E SHUTDOWN is active when pin 25 is driven high. For SP213E SHUTDOWN is active when pin 25 is driven low. The SP211E and SP213E feature a low- power shutdown mode, which reduces power supply drain to 1A. The SP213E includes a Wake-Up function which keeps two receivers active in the shutdown mode, unless disabled by the EN pin. Receivers The receivers convert RS-232 level input signals to inverted TTL level signals. Because signals are often received from a transmission line where long cables and system interference can degrade signal quality, the inputs have enhanced sensitivity to detect weakened signals. The receivers also feature a typical hysteresis margin of 500mV for clean reception of slowly transitioning signals in noisy conditions. These enhancements ensure that the receiver is virtually immune to noisy transmission lines. The family is available in 28 and 24 pin SO (wide) and SSOP (shrink) small outline packages. Devices can be specified for commercial (0C to +70C) and industrial/extended (-40C to +85C) operating temperatures. Theory of Operation Exar RS-232 transceivers contain three basic circuit blocks -- a) transmitter/driver, b) receiver and c) the EXAR-proprietary charge pump. SP211E and SP213E also include SHUTDOWN and ENABLE functions. Exar Corporation 48720 Kato Road, Fremont CA, 94538 * 510-668-7017 * www.exar.com SP207E_100_072309 Phase 2 -- VSS transfer and invert -- Phase two connects the negative terminal of C2 to the VSS storage capacitor and the positive terminal of C2 to ground. This transfers the doubled and inverted (V-) voltage onto C3. Meanwhile, capacitor C1 charged from VCC to prepare it for its next phase. Receiver input thresholds are between 1.2 to 1.7 volts typical. This allows the receiver to detect standard TTL or CMOS logic-level signals as well as RS-232 signals. If a receiver input is left unconnected or un-driven, a 5k pulldown resistor to ground will commit the receiver to a logic-1 output state. Highly Efficient Charge-Pump The onboard dual-output charge pump is used to generate positive and negative signal voltages for the RS-232 drivers. This enables fully compliant RS-232 and V.28 signals from a single power supply device. VCC = +5V C4 C1 + C2 - + - + - - + VDD Storage Capacitor VSS Storage Capacitor C3 -10V Figure 2. Charge Pump -- Phase 2 The charge pumps use four external capacitors to hold and transfer electrical charge. The Exar-patented design (US Patent #5,306,954) uses a unique approach compared to older, less-efficient designs. The pumps use a four-phase voltage shifting technique to attain symmetrical V+ and Vpower supplies. An intelligent control oscillator regulates the operation of the charge pump to maintain the proper voltages at maximum efficiency. Phase 3 VDD charge store and double --Phase three is identical to the first phase. The positive terminals of capacitors C1 and C2 are charged from VCC with their negative terminals initially connected to ground. Cl+ is then connected to ground and the stored charge from C1- is superimposed onto C2-. Since C2+ is still connected to VCC the voltage potential across capacitor C+5Vis now 2 x VCC.

This transfers the doubled (V+) voltage onto C4. Meanwhile, capacitor C1 is charged from VCC to prepare it for its next phase. C3 Figure 1. Charge Pump -- Phase 1 Exar Corporation 48720 Kato Road, Fremont CA, 94538 * 510-668-7017 * www.exar.com SP207E_100_072309 VCC = +5V +10V C1 + - C2 + - Voltage potential across any of the capacitors will never exceed 2 x VCC. Therefore capacitors with working voltages as low as 10V rating may be used with a nominal VCC supply. C1 will never see a potential greater than VCC , so a working voltage of 6.3V is adequate. The reference terminal of the VDD capacitor may be connected either to VCC or ground, but if connected to ground a minimum 16V working voltage is required. Higher working voltages and/or capacitance values may be advised if operating at higher VCC or to provide greater stability as the capacitors age. C4 + - - + VDD Storage Capacitor VSS Storage Capacitor C3 Figure 4. Charge Pump -- Phase 4 The Exar charge-pump generates V+ and Vindependently from VCC. Hence in a no-load condition V+ and V- will be symmetrical. Older charge pump approaches generate V+ and then use part of that stored charge to generate V-. Because of inherent losses, the magnitude of V- will be smaller than V+ on these older designs. Under lightly loaded conditions the intelligent pump oscillator maximizes efficiency by running only as needed to maintain V+ and V-. Since interface transceivers often spend much of their time at idle, this power-efficient innovation can greatly reduce total power consumption. This improvement is made possible by the independent phase sequence of the Exar charge-pump design. +10V a) C2+ GND GND b) C2- -10V The clock rate for the charge pump typically operates at greater than 15kHz, allowing the pump to run efficiently with small 0.1F capacitors. Efficient operation depends on rapidly charging and discharging C1 and C2, therefore capacitors should be mounted close to the IC and have low ESR (equivalent series resistance). Low cost surface mount ceramic capacitors (such as are widely used for power-supply decoupling) are ideal for use on the charge pump. Figure 5. Typical waveforms seen on capacitor C2 when all drivers are at maximum load. However the charge pumps are designed to be able to function properly with a wide range of capacitor styles and values. If polarized capacitors are used, the positive and negative terminals should be connected as shown. Exar Corporation 48720 Kato Road, Fremont CA, 94538 * 510-668-7017 * www.exar.com SP207E_100_072309 SHUTDOWN MODE SP211E and SP213E feature a control input which will shut down the device and reduce the power supply current to less than 10A, making the parts ideal for battery-powered systems. In shutdown mode the transmitters will be tri-stated, the V+ output of the charge pump will discharge to VCC, and the V- output will discharge to ground. Shutdown will tristate all receiver outputs of the SP211E. SHUTDOWN CONDITIONS For complete shutdown to occur and the 10A power drain to be realized, the following conditions must be met: SP211E: * +5V must be applied to the SD pin * ENABLE must be either Ground, +5.0V or not connected * the transmitter inputs must be either +5.0V or not connected * VCC must be +5V * Receiver inputs must be >0V and <+5V SP213E WAKEUP FUNCTION On the SP213E, shutdown will tri-state receivers 1-3. Receivers 4 and 5 remain active to provide a "wake-up" function and may be used to monitor handshaking and control inputs for activity. With only two receivers active during shutdown, the SP213E draws only 5-10A of supply current. SP213E: * 0V must be applied to the SD pin * ENABLE must be either 0V, +5.0V or not connected * the transmitter inputs must be either +5.0V or not connected * VCC must be +5V * Receiver inputs must be >0V and <+5V Many standard UART devices may be configured to generate an interrupt signal based on changes to the Ring Indicate (RI) or other inputs. A typical application of this function would be to detect modem activity with the computer in a power-down mode. The ring indicator signal from the modem could be passed through an active receiver in the SP213E that is itself in the shutdown mode. The ring indicator signal would propagate through the SP213E to the power management circuitry of the computer to power up the microprocessor and the SP213E drivers. After the supply voltage to the SP213E reaches +5.0V, the SHUTDOWN pin can be disabled, taking the SP213E out of the shutdown mode. All receivers that are active during shutdown maintain 500mV (typ.) of hysteresis. All receivers on the SP213E may be put into tri-state using the ENABLE pin.

This can be especially useful when the receiver is tied directly to a shared microprocessor data bus. For the SP211E, enable is active low; that is, ZeroV applied to the ENABLE pin will enable the receiver outputs. For the SP213E, enable is active high; that is, +5V applied to the ENABLE pin will enable the receiver outputs.

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 8. There are two methods within IEC1000-4-2, the Air Discharge method and the Contact Discharge method. ESD Tolerance The SP207E Family 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 electro-static discharges and associated transients. 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 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 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 7. 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, RS RC SW1 DC Power Source SW2 CS Device Under Test Figure 7. ESD Test Circuit for Human Body Model Exar Corporation 48720 Kato Road, Fremont CA, 94538 * 510-668-7017 * www.exar.com 10 SP207E_100_072309 Contact-Discharge Model RS RC RV SW1 SW2 Device Under Test CS DC Power Source R S and RV add up to 330 for IEC1000-4-2. Figure 8. ESD Test Circuit for IEC1000-4-2 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. 30A 15A 0A The circuit model in Figures 7 and 8 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. t=0ns t t=30ns Figure 9. ESD Test Waveform for IEC1000-4-2 (CS) are 1.5k an 100pF, respectively. For IEC-1000-4-2, the current limiting resistor (RS) and the source capacitor (CS) are 330 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. For the Human Body Model, the current limiting resistor (RS) and the source capacitor Exar Corporation 48720 Kato Road, Fremont CA, 94538 * 510-668-7017 * www.exar.com 11 SP207E_100_072309 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. The RS-232 is a relatively slow data exchange protocol, with a maximum baud rate of only 20kbps, which can be transmitted over a maximum copper wire cable length of 50 feet. The SP207E through SP213E Series of data communications interface products have been designed to meet both the EIA protocol standards, and the needs of the industry. EIA STANDARDS The Electronic Industry Association (EIA) developed several standards of data transmission which are revised and updated in order to meet the requirements of the industry. In data processing, there are two basic means of communicating between systems and components. The RS--232 standard was first introduced in 1962 and, since that time, has become an industry standard.
