SP331 Programmable Dual RS-232/RS-485 Transceiver Description FEATURES ■■ +5V Only Operation ■■ Software Programmable RS-232 or RS-485 Selection ■■ Four RS-232 Transceivers in RS-232 Mode ■■ Two RS-485 Full-Duplex Transceivers in RS-485 Mode ■■ Two RS-232 Transceivers and One RS-485 Transceiver in Dual Mode ■■ Self-Testing Loopback Mode ■■ Full Driver Tri-State (Hi-Z) Control ■■ Ideal for RS-232 to RS-485 conversion The SP331 is a programmable RS-232 and/or RS-485 transceiver IC. The SP331 contains four drivers and four receivers when selected in RS-232 mode; and two drivers and two receivers when selected in RS-485 mode. The SP331 also contains a dual mode which has two RS-232 drivers/receivers plus one differential RS-485 driver/receiver. The RS-232 transceivers can typically operate at 230kbps while adhering to the RS-232 specifications. The RS-485 transceivers can operate up to 10Mbps while adhering to the RS-485 specifications. The SP331 includes a self-test loopback mode where the driver outputs are internally configured to the receiver inputs. This allows for easy diagnostic serial port testing without using an external loopback plug. The RS-232 and RS-485 drivers can be disabled (High-Z output) by controlling a set of four select pins.

Mode Function Table (Refer to Control Logic Confirmations for Block Diagrams) Theory of Operation The SP331 is made up of four separate circuit blocks: the charge pump, drivers, receivers, and decoder. Each of these circuit blocks is described in more detail below. Charge-Pump The charge pump is an Exar–patented design (U.S. 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 shifting technique to attain symmetrical 10V power supplies. Figure 15(a) shows the waveform found on the positive side of capacitor C2, and Figure 15(b) shows the negative side of capacitor 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. C1+ is then switched to ground and charge on 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 -10V to C3. 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 10V. Phase 4: VDD Transfer The fourth phase of the clock connects the negative terminal of C2 to ground and transfers the generated 10V 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 must be 0.1µF with a 16V breakdown rating.

Charge Pump Waveforms REV 1.0.1 9/13 SP331 External Power Supplies For applications that do not require +5V only, external supplies can be applied at the V+ and V– pins. The value of the external supply voltages must be no greater than ±10V. The current drain for the ±10V supplies is used for RS-232. For the RS-232 driver the current requirement will be 3.5mA per driver. The external power supplies should provide a power supply sequence of: +10V, then +5V, followed by -10V. Drivers The SP331 has four independent RS-232 single-ended drivers and two differential RS-485 drivers. Control for the mode selection is done via a four–bit control word. The drivers are pre-arranged such that for each mode of operation the relative position and functionality of the drivers are set up to accommodate the selected interface mode. As the mode of the drivers is changed, the electrical characteristics will change to support the requirements of clock, data, and control line signal levels. Unused driver inputs can be left floating; however, to ensure a desired state with no input signal, pull–up resistors to +5V or pull– down resistors to ground are suggested. Since the driver inputs are both TTL or CMOS compatible, any value resistor less than 100kΩ will suffice. When in RS-232 mode, the single-ended RS-232 drivers produce compliant RS-232E and ITU V.28 signals. Each of the four drivers output single-ended bipolar signals in excess of ±5V with a full load of 3kΩ and 2500pF applied as specified. These drivers can also operate at least 120kbps. When programmed to RS-485 mode, the differential RS485 drivers produce complaint RS-485 signals. Each RS485 driver outputs a unipolar signal on each output pin with a magnitude of at least 1.5V while loaded with a worst case of 54Ω between the driver’s two output pins. The signal levels and drive capability of the RS-485 drivers allow the drivers to also comply with RS-422 levels. The transmission rate for the differential drivers is 10Mbps. The RS-232 receiver has a single–ended input with a threshold of 0.8V to 2.4V. The RS-232 receiver has an operating voltage range of ±15V and can receive signals up to 120kbps. RS-232 receivers are used in RS-232 mode for all signal types include data, clock, and control lines of the RS-232 serial port. The differential RS-485 receiver has an input impedance of 15kΩ and a differential threshold of ±200mV. Since the characteristics of an RS-422 receiver are actually subsets of RS-485, the receivers for RS-422 requirements are identical to the RS-485 receivers. All of the differential receivers can receive data up to 10Mbps. Select Mode Pins Similar to our SP500 family of multiprotocol products, the SP331 has the ability to change the configuration of the drivers and receivers via a 4–bit switch. Referring to Table 1; RS-232 mode, RS-485 mode, or two different combinations of RS-232/RS-485 can be configured using the SEL_A and SEL_B pins. The drivers can be put into tri-state mode by using the SEL_C and SEL_D pins. All receivers remain active during any tri-state condition of the drivers. Loopback Mode Loopback is invoked by asserting “xx11” into the select pins. In RS-232 / RS-485 or RS-485 / RS-232 loopback mode, the RS-232 driver outputs loop back into the RS-232 receiver inputs and the RS-485 differential driver loops back into the RS-485 receiver. During loopback, the driver outputs and receiver inputs are disconnected from the outside world. The driver outputs are in tri-state and the receiver inputs are disabled. The input impedance of the receivers during loopback is approximately 15kΩ to ground. Receivers The SP331 has four single-ended receivers when programmed for RS-232 mode and two differential receivers when programmed for RS-485 mode. Control for the mode selection is done via a 4–bit control word, as in the drivers. As the operating mode of the receivers is changed, the electrical characteristics will change to support the requirements of the appropriate serial standard. Unused receiver inputs can be left floating without causing oscillation. To ensure a desired state of the receiver output, a pull–up resistor of 100kΩ to +5V should be connected to the inverting input for a logic low, or the non–inverting input for a logic high. For single-ended receivers, a pull–down resistor to ground of 5kΩ is internally connected, which will ensure a logic high output.
