The I2C/ SMBus GPIO Expanders are pin and software compatible to existing 8-bit and 16-bit I2C/SMBus GPIO Expanders, but with enhanced features and functionality. The SPI GPIO Expanders operate with a high speed SPI clock of up to 26MHz. Individually Programmable Each GPIO can be individually configured as an input or an output. In addition, each feature listed below can individually enabled or disabled for each GPIO. Stored Interrupt Status The GPIO Expanders have an interrupt status register which allows the software in the host controller to easily identify which input generated the interrupt. The GPIO Expander can also be configured so that the interrupt status remains in the status register even after the input has changed back to its original state. Internal Pull-up Resistors When configured as an input, the internal pull-up resistor can be enabled for selected GPIOs configured as inputs. Exar’s “P” devices Input Glitch Filtering have the internal pull-up resistor enabled at power-up, which can be Selectable GPIO input filtering ignores pulses that are less than 225 individually disabled on each input. ns. The GPIO state will not be updated and there will not be any interrupts reported from noise or small glitches when this feature is Rising / Falling Edge Interrupts enabled. Each GPIO input can be configured to generate an interrupt on the rising edge, falling edge, or both edges. Tri-State Outputs GPIO outputs can be individually tri-stated. This is useful for Interrupt Mask / Enable applications where the GPIO output is connected to an input of a Interrupts can be masked / enabled for each GPIO input so that only device that is powered down, or when driving a tri-state logic input pin. selected inputs will generate interrupts.

Exar is the market leader in high-speed RS-485/RS-422 and Multiprotocol transceivers. In addition, Exar offers a broad family of feature-rich RS-232 serial transceivers. Exar uses state of the art structures to protect the transceiver pins against ESD of ±15kV without damage. The ESD structures withstand high ESD in all states: normal operation, shutdown and powered down. After an ESD event, the transceivers keep working without latch-up or damage. ESD protection can be tested in various ways. The transmitter outputs and receiver inputs are characterized for protection to the following limits: • ±15kV using the Human Body Model • ± 8kV using the Contact Discharge method specified in IEC 61000-4-2 • ±15kV using the Air-Gap Discharge method specified in IEC 61000-4-2 Key Features and Technologies Pin-to-Pin Compatibility Exar’s RS-232 and RS-485/422 transceivers are offered in industry standard packages and pinouts. Therefore, migrating to faster RS232 or RS-485/422 transceivers with additional features can be accomplished with minimal changes to the design. Internal Termination The SP338E and SP339E dual protocol transceivers offer internal cable termination in RS-485/422 modes. The SP3508, SP508E and SP510E also offer internal V.11 and V.35 termination networks for the clock and data lines. Eliminating the external termination greatly simplifies the system design, resulting in reduced board space and quicker time to market. Hot Swap / Power-Up Glitch Protection This feature prevents random data errors from appearing on the RS485/422 differential pairs due to undefined logic levels during powerup that improperly enable the transceivers. Auto On-Line® Feature Auto On-Line saves power by turning off the charge pumps and driver outputs when the RS-232 inputs see less than valid +/-3V signals (ie. cable is unplugged). The RS-232 transceiver will automatically wake up from the low power state when a valid RS-232 voltage is sensed at the receiver input. Auto On-Line® Plus Feature Similar to above, Auto On-Line Plus saves power by turning off the charge pumps and driver outputs if there are no transitions on the driver or receiver inputs for 30 seconds. The transceiver returns to normal operation with a transition on any of the driver or receiver inputs. Highly Efficient Charge Pump The charge pump is used to generate positive and negative signal voltages for the RS-232 drivers. This enables fully compliant RS-232 and V.28 signals from a single 3.0 or 5.5V power supply. The charge pumps use four external capacitors to hold and transfer electrical charge. The patented design uses a unique approach compared to older less efficient designs. 1/8th Unit Load A standard RS-485/422 driver can drive up to 32 unit loads. The 1/8th unit load receiver input impedance allows eight times as many transceivers (up to 256) to be connected in parallel on a communication Industry’s ONLY Single Chip Solutions line. Exar is the only one in the industry to offer single chip solutions that support RS-232, RS-485, RS-449, EIA-530, V.10, V.11, V.28, V.35, Enhanced Receiver Failsafe V.36, and X.21. As a result, Exar’s solution takes up to 40% less board The Enhanced Receiver Failsafe feature ensures that the TTL space than competitor solutions. outputs are in a known state when the RS-485/422 differential pairs are floating, shorted, or terminated but idle, without the need for any NET1/2 and TBR2 Compliance external biasing resistors. SP3508, SP505, SP506, SP507, and SP508E are compliant to NET1/2 and TBR2 requirements. PROFIBUS PROFIBUS is widely used in industrial control and automation Slew Rate Limited Options applications and is ruggedized for use in harsh operating conditions. Slew limited drivers minimize EMI (Electromagnetic Interference) Exar’s products are PROFIBUS compliant and feature high differential and reduce reflections caused by improperly terminated cables. This output swing for improved noise immunity or to drive longer data allows for error-free data transmission over longer communication cables. lines. 13 CONNECTIVIT Y → SERIAL TRANSCEIVERS → Multiprotocol Transceivers Exar offers the industry’s only single chip multiprotocol solutions and the fastest data rates, up to 52 Mbps.
