Their data transmission rate of 460Kbps meeting the demands of high speed RS-232 applications. Both ICS have a high-efficiency, charge-pump power supply that requires only 0.1µF capacitors for 3.3V operation. The charge pump allows the SP3222H and the 3232H series to deliver true RS-232 performance from a single power supply ranging from +3.3V to +5.0V. The SP3222H device has a low-power shutdown mode where the devices' driver outputs and charge pumps are disabled. During shutdown, the supply current is less than 1µA.

The SP3222H features a 1µA shutdown mode that reduces power consumption and extends battery life in portable systems. Its receivers remain active in shutdown mode, allowing external devices such as modems to be monitored using only 1µA supply current. The slew rate of the driver output is internally limited to a maximum of 30V/µs 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. Figure 8 shows a loopback circuit used to test the RS-232 drivers. Figure 9 shows the test results of the loopback circuit with all drivers active at 120Kbps and RS-232 loads in parallel with 1000pF capacitors. Figure 10 shows the test results where one driver is active at 460Kbps and all drivers are loaded with an RS-232 receiver in parallel with a 1000pF capacitor. The SP3222H/3232H transceivers meet the EIA/ TIA-232 and V.28/V.24 communication protocols. They feature Sipex's proprietary on-board charge pump circuitry that generates 2 x VCC for RS-232 voltage levels from a single +3.0V to +5.5V power supply. The SP3222H/ 3232H drivers operate at a minimum data rate of 460Kbps. The SP3222H driver's output stages are tri-stated in shutdown mode. When the power is off, the SP3222H device permits the outputs to be driven up to +12V. Because the driver's inputs do not have pull-up resistors, unused inputs should be connected to VCC or GND. THEORY OF OPERATION The SP3222H/3232H are made up of three basic circuit blocks: 1. Drivers, 2. Receivers, and 3. the Sipex proprietary charge pump. In the shutdown mode, the supply current is less than 1µA, where SHDN = LOW. When the SP3222H device is shut down, the device's driver outputs are disabled (tri-stated) and the charge pumps are turned off with V+ pulled down to VCC and V- pulled to GND. The time required to exit shutdown is typically 100µs. SHDN is connected to VCC if the shutdown mode is not used. SHDN has no effect on RxOUT or RxOUTB. As they become active, the two driver outputs go to opposite RS-232 levels: one driver input is HIGH and the other LOW. Note that the drivers are enabled only when the magnitude of V- exceeds approximately 3V. Drivers The drivers are inverting level transmitters that convert TTL or CMOS logic levels to +5.0V EIA/TIA-232 levels inverted relative to the input logic levels. Typically, the RS-232 output voltage swing is +5.5V with no load and at least +5V minimum fully loaded. The driver outputs are protected against infinite short-circuits to ground without degradation in reliability. Driver outputs will meet EIA/TIA-562 levels of +3.7V with supply voltages as low as 2.7V. The drivers have a minimum data rate of 460Kbps fully loaded with 3KΩ in parallel with 1000pF, ensuring compatibility with PC-to-PC communication software.

The SP3222H receivers have an inverting tri-state output.Receiver outputs (RxOUT) are tri-stated when the enable control EN = HIGH. In the shutdown mode, the receivers can be active or inactive. EN has no effect on TxOUT. The truth table logic of the SP3222H driver and receiver outputs can be found in Table 2. In most circumstances, decoupling the power supply can be achieved adequately using a 0.1µF bypass capacitor at C5 (refer to Figures 6 and 7). In applications that are sensitive to power-supply noise,VCC and ground can be decoupled with a capacitor of the same value as charge-pump capacitor C1. It is always important to physically locate bypass capacitors close to the IC. Since receiver input is usually from a transmission line where long cable lengths and system interference can degrade the signal and inject noise, the inputs have a typical hysteresis margin of 300mV. Should an input be left unconnected, a 5kΩ pulldown resistor to ground forces the output of the receiver HIGH. The charge pump operates in a discontinuous mode using an internal oscillator. If the output voltage is less than 5.5V, the charge pump is enabled. If the output voltage exceeds 5.5V, the charge pump is disabled. An oscillator controls the four phases of the voltage shifting. A description of each phase follows. Charge Pump Phase 1: VSS Charge Storage (Figure 12) During this phase of the clock cycle, the positive side of capacitors C1 and C2 are 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. The Sipex patented charge pump (5,306,954) uses a four–phase voltage shifting technique to attain symmetrical 5.5V power supplies and requires four external capacitors. The internal power supply consists of a regulated dual charge pump that provides an output voltage of 5.5V regardless of the input voltage (VCC) over the +3.0V to +5.5V range. SHDN EN TxOUT RxOUT 0 0 Tri-state Active 0 1 Tri-state Tri-state 1 0 Active Active 1 1 Active Tri-state Phase 2: VSS Transfer (Figure 13) 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 C3. 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: VDD Charge Storage (Figure 15) 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. Table 2. Truth Table Logic for Shutdown and Enable Control Rev. 6/27/03 SP3222H/3232H 3.3V, 460 Kbps RS-232 Transceivers 10 © Copyright 2003 Sipex Corporation Phase 4: VDD Transfer (Figure 16) 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 repeat. The charge pump cycle will continue as long as the operational conditions for the internal oscillator are present. ESD Tolerance The SP3222H/3232H series incorporates ruggedized ESD cells on all driver output and receiver input pins. The Human Body Model has been the generally accepted ESD testing method for semiconductors. This method is also specified in MIL-STD883, 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 17. 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. 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. For the Human Body Model, the current limiting resistor (RS) and the source capacitor (CS) are 1.5kΩ and 100pF, respectively. The charge pump clock rate typically operates at 250kHz. The external capacitors can be as low as 0.1µF with a 16V breakdown voltage rating. VCC = +5V C4 +5V + C1 C2 – –5V + – – + + – VDD Storage Capacitor VSS Storage Capacitor C3 –5V Figure 12.
