These devices feature very low power consumption and single-supply operation making them ideal for space-constrained applications. Sipex-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 IEC10004-2 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 con-struction and SIPEX-proprietary onboard 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 SP211 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 Sipex RS232 transceivers contain three basic circuit blocks -- a) transmitter/driver, b) receiver and c) the SIPEX-proprietary charge pump. SP211E and SP213E also include SHUTDOWN and ENABLE functions. Date: 1/27/06 SP207E Low Power, High ESD +5V RS232 Transceivers 5 (c) Copyright 2006 Sipex Corporation 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 RS232 signals. If a receiver input is left unconnected or undriven, a 5k pulldown resistor to ground will commit the receiver to a logic-1 output state. 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. VCC = +5V HIGHLY EFFICIENT CHARGE-PUMP The onboard dual-output charge pump is used to generate positive and negative signal voltages for the RS232 drivers. This enables fully compliant RS232 and V.28 signals from a single power supply device. C1 The charge pumps use four external capacitors to hold and transfer electrical charge. The Sipex-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.

The positive terminals of capacitors C1 and C2 are charged from VCC with their negative terminals initially connected to ground.

This improvement is made possible by the independent phase sequence of the Sipex charge-pump design. 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 VCC = +5V rapidly charging and discharging C1 and C2, therefore capacitors should be mounted close to the IC and have low ESR (equivalent C4 +10V series resistance). Low cost surface mount + - V Storage Capacitor DD ceramic capacitors (such as are widely used + + C1 C2 for power-supply decoupling) are ideal for - - - + VSS Storage Capacitor use on the charge pump.

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. All receivers that are active during shutdown maintain 500mV (typ.) of hysteresis. All receivers on the SP213E may be put into tristate using the ENABLE pin. SHUTDOWN CONDITIONS For complete shutdown to occur and the 10A power drain to be realized, the following conditions must be met: 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. 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 greater than Ground and less than +5V A typical application of this function would be where a modem is interfaced to a 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. SP213E: * Zero Volts 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 greater than Ground and less than +5V Date: 1/27/06 SP207E Low Power, High ESD +5V RS232 Transceivers 8 (c) Copyright 2006 Sipex Corporation RECEIVER ENABLE SP211E and SP213E feature an enable input, which allows the receiver outputs to be either tri-stated or enabled. 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, Zero Volts 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. SD# 0 0 1 1 Table 2.

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. 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 8. There are two methods within IEC1000-4-2, the Air Discharge method and the Contact Discharge method. 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 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. 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 R RS S R RC C SW2 SW2 SW1 SW1 C CS S DC Power Source Device Under Test Figure 7.

ESD Test Circuit for IEC1000-4-2 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. 30A 15A 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. 0A t=0ns t=30ns t Figure 9. ESD Test Waveform for IEC1000-4-2 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-1000-4-2, the current limiting resistor (RS) and the source capacitor (CS) are 330W an 150pF, respectively. 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 RS--232 standard was first introduced in 1962 and, since that time, has become an industry standard. 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.
