The ESD tolerance has been improved on these devices to over ±15kV for Human Body Model. These devices are pin-topin compatible with MaxLinear’s SP232A and SP233A as well as popular industry standards.This family of parts offer a 120kbps data rate, 10V/us slew rate and an on-board charge pump that operates from a single 5V supply using 0.1µF ceramic capacitors. The SP202E, SP232E and SP233E devices have internal charge pump voltage converters which allow them to operate from a single +5V supply. The charge pumps will operate with polarized or non-polarized capacitors ranging from 0.1 to 10µF and will generate the ±6V needed to generate the RS-232 output levels. The SP233E design offers internal charge pump capacitors. In actual system applications, it is quite possible for signals to be applied to receiver inputs before power is applied to the receiver circuitry. This occurs, for example, when a PC user attempts to print, only to realize that the printer wasn't turned on. In this case an RS-232 signal from the PC will appear on the receiver input at the printer. When the printer power is turned on, the receiver will operate normally. All of these devices are fully protected. Charge pump Theory Of Operation The SP202E, SP232E and SP233E devices are made up of three basic circuit blocks: 1. Drivers, 2. Receivers, and 3. charge pump. Each block is described below. Drivers The drivers are inverting level transmitters that convert TTL or CMOS logic levels to EIA / TIA-232 levels with an inverted sense relative to the input logic levels. The typical driver output voltage swing is ±6V. Even under worst case loading conditions of 3kΩ and 2500pF, the driver output is guaranteed to be ±5.0V minimum, thus satisfying the RS-232 specification. The driver outputs are protected against infinite short-circuits to ground without degradation in reliability. The slew rate of the driver output is internally limited to 30V/µs in order to meet the EIA standards (EIA-232F). Additionally, the driver outputs LOW to HIGH transition meets the monotonic output requirements of the standard. Receivers The receivers convert EIA / TIA-232 signal levels to inverted TTL or CMOS logic output levels. Since the input is usually from a transmission line, where long cable length 3/28/19 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. The input thresholds are 0.8V minimum and 2.8V maximum, again well within the ±3V RS-232 requirements. Should an input be left unconnected, an internal 5kΩ pulldown resistor to ground will commit the output of the receiver to a HIGH state. The charge pump is an Exar patented design and uses a unique approach compared to older less efficient designs. The charge pump requires 4 external capacitors and uses a four phase voltage shifting technique. The internal power supply consists of a dual charge pump that provides a driver output voltage swing of ±6V. The internal oscillator controls the four phases of the voltage shifting. A description of each phase follows: Phase 1 VSS charge store and double: The positive terminals of capacitors C1 and C2 are charged from VCC with their negative terminals initially connected to ground. C1+ is then connected to ground and the stored charge from C1is superimposed onto C2-. Since C2+ is still connected to VCC the voltage potential across C2 is now 2 x VCC. 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 C4. Meanwhile, capacitor C1 is charged from VCC to prepare it for its next phase. Rev 1.0.2 5 SP202E, SP232E, SP233E High Performance RS-232 Line Drivers / Receivers Phase 3 VDD charge store and double: Phase three is identical to the first phase. The positive terminals of C1 and C2 are charged from VCC with their negative terminals initially connected to ground. C1+ 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 C2 is now 2 x VCC. Phase 4 VDD transfer: The fourth phase connects the negative terminal of C2 to ground and the positive terminal of C2 to Description the VDD storage capacitor. This transfers the doubled (V+) voltage onto C3. Meanwhile, capacitor C1 is charged from VCC to prepare it for its next phase. The clock rate for the charge pump typically operates at greater than 15kHz allowing the pump to run efficiently with small 0.1µF capacitors. Efficient operation depends on rapid charging and discharging of C1 and C2, therefore capacitors should be mounted as close as possible to the IC and have low ESR (equivalent series resistance). Inexpensive surface mount, ceramic capacitors are ideal for use on the charge pump. If polarized capacitors are used, the positive and negative terminals should be connected as shown in the typical operating circuit. A diagram of the individual phases are shown in Figure 8. + V CC - Phase 2 – Vss transfer from C2 to C4. Meanwhile C1 is charged to Vcc + + V CC - C Phases 1 and 3: Store/Double.

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 Human Body Model without damage nor latchup. 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 9. This method will test the IC's capability to withstand an ESD transient during normal handling such as in manufacturing areas where the IC's tend to be handled frequently.
