DESCRIPTION The SP200E Series are enhanced multi-channel RS-232 line transceivers with improved electrical performance. The SP200E family is pin-to-pin compatible with our previous SP200 family as well as popular industry standards. As with the orignal SP200 family, all models in this Series feature low-power CMOS construction and Sipex-patented (5,306,954) on-board charge pump circuitry to generate the 10V RS-232 voltage levels, using 0.1F charge pump capacitors to save board space and reduce circuit cost. The SP211E and SP213E models feature a low-power shutdown mode, which reduces power supply drain to 1A. Enhancements include lower power supply current at 3mA typical (no load) and superior ESD performance. The ESD tolerance has been improved on this family to over 15kV for both Human Body Model and IEC1000-4-2 Air Discharge test methods.

FEATURES As in the original RS-232 multi-channel products, the SP207E Series multi-channel RS-232 line transceivers provide a variety of configurations to fit most communication needs, especially those applications where +12V is not available. All models in this Series feature low-power CMOS construction and SIPEX- proprietary on-board charge pump circuitry to generate the +10V RS-232 voltage levels. The ability to use 0.1F charge pump capacitors saves board space and reduces circuit cost. Different models within the Series provide different driver/receiver combinations to match any application requirement. The SP211 and SP213E models 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. The family is available in 28-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 The SP207E Series devices are made up of three basic circuit blocks -- 1) transmitter/ driver, 2) receiver and 3) the SIPEX- proprietary charge pump. Each model within the Series incorporates variations of these circuits to achieve the desired configuration and performance.
Charge-Pump The charge pump is a Sipex-patented design (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 10V power supplies. Figure 3a shows the waveform found on the positive side of capcitor C2, and Figure 3b shows the negative side of capcitor C2. There is a free-running oscillator that controls the four phases of the voltage shifting. A description of each phase follows. Phase 1 -- VSS charge storage --During this phase of the clock cycle, the positive side of capacitors C1 and C2 are initially charged to +5V. Cl+ is then switched to ground and the charge in C1- is transferred to C2-. Since C2+ is connected to +5V, the voltage potential across capacitor C2 is now 10V. Phase 2 -- 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 ground, and transfers the generated -l0V to C 3. Simultaneously, the positive side of capacitor C 1 is switched to +5V and the negative side is connected to ground. Phase 3 -- VDD charge storage -- The third phase of the clock is identical to the first phase -- the charge transferred in C1 produces -5V in the negative terminal of C1, which is applied to the negative side of capacitor C2. Since C2+ is at +5V, the voltage potential across C2 is l0V.

Figure 2. Charge Pump -- Phase 2
Phase 4 -- VDD transfer -- The fourth phase of the clock connects the negative terminal of C2 to ground, and transfers the generated l0V across C2 to C4, the VDD storage capacitor. Again, simultaneously with this, the positive side of capacitor C1 is switched to +5V and the negative side is connected to ground, and the cycle begins again. 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 15kHz. The external capacitors can be as low as 0.1F with a 16V breakdown voltage rating.
Transmitter/Driver The drivers are 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. Typically, the RS-232 output voltage swing is +9V with no load, and +5V minimum with full load. The transmitter outputs are protected against infinite short-circuits to ground without degradation in reliability. The drivers of the SP211E, and SP213E can be tri-stated by using the SHUTDOWN function. In the "power-off" state, the output impedance will remain greater than 300 ohms, again satisfying the RS-232 specifications. Should the input of the driver be left open, an internal 400Kohm pullup resistor to VCC forces the input high, thus committing the output to a low state. The slew rate of the transmitter 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.

Receivers The receivers convert RS-232 input signals to inverted TTL signals. Since the 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 virtually immune to noisy transmission lines. Should an input be left unconnected, a 5k pulldown resistor to ground will commit the output of the receiver to a high state. SHUTDOWN MODE The SP211E, and SP213E all feature a control input which will disable the device and reduce the power supply current to less than 10A, making the parts ideal for battery-powered systems. In the "shutdown" mode the receivers and transmitters will both be tri-stated. The V+ output of the charge pump will discharge to VCC, and the V- output will discharge to ground. Products with the Wake-Up function can enable or disable the receivers during shutdown.
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 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 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

ENABLE The SP211E and SP213E all 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 microprocessor data bus. For the SP211E, enable is active low; that is, 0V 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.

WAKEUP FUNCTION The SP213E has a wake-up feature that keeps two receivers (R4 and R5) in an enabled state when the device is in the shutdown mode. With only the receivers active during shutdown, the devices draw 5-10A of supply current. 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. All receivers that are active during shutdown maintain 500mV (typ.) of hysteresis. 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
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, 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 IEC10004-2, 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 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.

For the Human Body Model, the current limiting resistor (RS) and the source capacitor (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. 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.
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.
