ISL8563E ® Data Sheet July 2004 +/-15kV ESD Protected, +3V to +5.5V, 1Microamp, 250kbps, EIA/TIA-562, EIA/TIA-232 Transmitters/Receivers Features • ESD Protection for RS-562 I/O Pins to ±15kV (IEC61000) The Intersil ISL8563E contains 3.0V to 5.5V powered transmitters/receivers which meet ElA/TIA-562 and ElA/TIA-232 specifications, even at VCC = 3.0V. Additionally, they provide ±15kV ESD protection (IEC61000-4-2 Air Gap and Human Body Model) on transmitter outputs and receiver inputs (RS-562 pins). Targeted applications are PDAs, Palmtops, and notebook and laptop computers where the low operational, and even lower standby, power consumption is critical. Efficient on-chip charge pumps, coupled with a manual powerdown function, reduce the standby supply current to a 1µA trickle. Small footprint packaging, and the use of small, low value capacitors ensure board space savings as well. Data rates greater than 250kbps are guaranteed at worst case load conditions. The ISL8563E is fully compatible with 3.3V only systems, mixed 3.3V and 5.0V systems, and 5.0V only systems. This product features an improved charge pump which delivers ±5V transmitter supplies, allowing the use of the ISL8563E in RS-562 and RS-232 applications. RS-562 applications will benefit from the improved noise immunity afforded by the ±5V output swing capability. Table 1 summarizes the features of the device represented by this data sheet, while Application Note AN9863 summarizes the features of each device comprising the 3V RS-232 family.

TRANSMITTER OUTPUT ENABLE AND DISABLE TIMING ISL8563E Detailed Description The ISL8563E operates from a single +3V to +5.5V supply, guarantees a 250kbps minimum data rate, requires only four small external 0.1µF capacitors, features low power consumption, and meets all ElA/TIA-562 and EIA/TIA-232 specifications. The circuit is divided into three sections: The charge pump, the transmitters, and the receivers. (VCC = 0V). The receivers’ Schmitt trigger input stage uses hysteresis (even in powerdown) to increase noise immunity and decrease errors due to slow input signal transitions. The ISL8563E inverting receivers disable only when EN is driven high. Standard receivers driving powered down peripherals must be disabled to prevent current flow through the peripheral’s protection diodes (see Figures 4 and 5). Charge-Pump VCC Intersil’s new ISL8563E utilizes regulated on-chip dual charge pumps as voltage doublers, and voltage inverters to generate ±5.5V transmitter supplies from a VCC supply as low as 3.0V. This allows these devices to maintain RS-232 compliant output levels over the ±10% tolerance range of 3.3V powered systems. The efficient on-chip power supplies require only four small, external 0.1µF capacitors for the voltage doubler and inverter functions over the full VCC range. The charge pumps operate discontinuously (i.e., they turn off as soon as the V+ and V- supplies are pumped up to the nominal values), resulting in significant power savings. Transmitters The transmitters are proprietary, low dropout, inverting drivers that translate TTL/CMOS inputs to EIA/TIA-562/232 output levels. Coupled with the on-chip ±5.5V supplies, these transmitters deliver true RS-562/232 levels over a wide range of single supply system voltages. All transmitter outputs disable and assume a high impedance state when the device enters the powerdown mode (see Table 2). These outputs may be driven to ±12V when disabled. All devices guarantee a 250kbps data rate (VOUT = ±5V) for full load conditions (3kΩ and 1000pF), VCC ≥ 3.0V, with one transmitter operating at full speed. Under more typical conditions of VCC ≥ 3.3V, RL = 3kΩ, and CL = 250pF, one transmitter easily operates at 900kbps. Unused transmitter inputs may be left unconnected because they will be pulled to VCC by the on-chip pull-up resistors. Forcing the ISL8563E into power down disables the pull-up resistors to further minimize power. Receivers The ISL8563E contains standard inverting receivers that three-state via the EN control line. All the receivers convert RS-562/232 signals to CMOS output levels and accept inputs up to ±25V while presenting the required 3kΩ to 7kΩ input impedance (see Figure 3) even if the power is off RXOUT RXIN -25V ≤ VRIN ≤ +25V 5kΩ GND ≤ VROUT ≤ VCC GND FIGURE 3. INVERTING RECEIVER CONNECTIONS Powerdown Functionality This 3V device requires a nominal supply current of 0.3mA during normal operation (not in powerdown mode). This is considerably less than the 5mA to 11mA current required by 5V devices. The already low current requirement drops significantly when the device enters powerdown mode. In powerdown, supply current drops to 1µA, because the onchip charge pump turns off (V+ collapses to VCC, Vcollapses to GND), the transmitter outputs three-state, and the transmitter input pull-ups disable. This micro-power mode makes the ISL8563E ideal for battery powered and portable applications. Software Controlled (Manual) Powerdown The ISL8563E, is forced into its low power, stand by state via a simple shutdown (SHDN) pin. Driving this pin high enables normal operation, while driving it low forces the IC into its powerdown state. Connect SHDN to VCC if the powerdown function isn’t needed. Note that all the receiver outputs remain enabled during shutdown (see Table 2). For the lowest power consumption during powerdown, the receivers should also be disabled by driving the EN input high (see next section, and Figures 4 and 5). The time required to exit powerdown, and resume transmission is less than 30µs. Receiver ENABLE Control The device also features an EN input to control the receiver outputs. Driving EN high disables all the receiver outputs placing them in a high impedance state. This is useful to eliminate supply current, due to a receiver output forward biasing the protection diode, when driving the input of a powered down (VCC = GND) peripheral (see Figure 4). The enable input has no effect on transmitters. TABLE 2.

In applications that are particularly sensitive to power supply noise, decouple VCC to ground with a capacitor of the same value as the charge-pump capacitor C1. Connect the bypass capacitor as close as possible to the IC. VCC VCC CURRENT FLOW VOUT = VCC Rx POWERED DOWN UART Operation Down to 2.7V Tx GND SHDN = GND ISL8563E transmitter outputs meet RS-562 levels (±3.7V), at the full data rate, with VCC as low as 2.7V. RS-562 levels typically ensure interoperability with RS-232 devices. OLD RS-562/232 CHIP FIGURE 4. POWER DRAIN THROUGH POWERED DOWN PERIPHERAL Figure 6 shows the response of two transmitter outputs when exiting powerdown mode. As they activate, the two transmitter outputs properly go to opposite RS-562/232 levels, with no glitching, ringing, nor undesirable transients. Each transmitter is loaded with 3kΩ in parallel with 2500pF. Note that the transmitters enable only when the magnitude of the supplies exceed approximately 3V.

DISABLED RECEIVERS PREVENT POWER DRAIN VCC = +3.3V C1 - C4 = 0.1µF Capacitor Selection TIME (20µs/DIV) The charge pumps operate with 0.1µF (or greater) capacitors for 3.0V ≤ VCC ≤ 5.5V. Increasing the capacitor values (by a factor of 2) reduces ripple on the transmitter outputs and slightly reduces power consumption. C2, C3, and C4 can be increased without increasing C1’s value, however, do not increase C1 without also increasing C2, C3, and C4 to maintain the proper ratios (C1 to the other capacitors). When using minimum required capacitor values, make sure that capacitor values do not degrade excessively with temperature. If in doubt, use capacitors with a larger nominal value. The capacitor’s equivalent series resistance (ESR) usually rises at low temperatures and it influences the amount of ripple on V+ and V-. 6 FIGURE 6. TRANSMITTER OUTPUTS WHEN EXITING POWERDOWN High Data Rates The ISL8563E maintains the RS-232 ±5V minimum transmitter output voltages even at high data rates. Figure 7 details a transmitter loopback test circuit, and Figure 8 illustrates the loopback test result at 120kbps. For this test, all transmitters were simultaneously driving RS-232 loads in parallel with 1000pF, at 120kbps. Figure 9 shows the loopback results for a single transmitter driving 1000pF and an RS-232 load at 250kbps. The static transmitters were also loaded with an RS-232 receiver.

LOOPBACK TEST AT 120kbps All pins on Intersil 3V interface devices include ESD protection structures, but the ISL8XXXE family incorporates advanced structures which allow the RS-562/232 pins (transmitter outputs and receiver inputs) to survive ESD events up to ±15kV. These pins are particularly vulnerable to ESD damage because they typically connect to an exposed port on the exterior of the finished product. Simply touching the port pins, or connecting a cable, can cause an ESD event that might destroy unprotected ICs. These new ESD structures protect the device whether or not it is powered up, protect without allowing any latchup mechanism to activate, and don’t interfere with RS-562/232 signals as large as ±25V. Human Body Model (HBM) Testing As the name implies, this test method emulates the ESD event delivered to an IC during human handling. The tester delivers the charge through a 1.5kΩ current limiting resistor, making the test less severe than the IEC61000 test which utilizes a 330Ω limiting resistor. The HBM method determines an ICs ability to withstand the ESD transients typically present during handling and manufacturing. Due to the random nature of these events, each pin is tested with respect to all other pins. The RS-562/232 pins on “E” family devices can withstand HBM ESD events to ±15kV. 5V/DIV T1IN T1OUT IEC61000-4-2 Testing R1OUT VCC = +3.3V C1 - C4 = 0.1µF 2µs/DIV FIGURE 9. LOOPBACK TEST AT 250kbps 7 The IEC61000 test method applies to finished equipment, rather than to an individual IC. Therefore, the pins most likely to suffer an ESD event are those that are exposed to the outside world (the RS-562/232 pins in this case), and the IC is tested in its typical application configuration (power applied) rather than testing each pin-to-pin combination. The lower current limiting resistor coupled with the larger charge ISL8563E storage capacitor yields a test that is much more severe than the HBM test. The extra ESD protection built into this device’s RS-562/232 pins allows the design of equipment meeting level 4 criteria without the need for additional board level protection on the RS-562/232 port. AIR-GAP DISCHARGE TEST METHOD For this test method, a charged probe tip moves toward the IC pin until the voltage arcs to it. The current waveform delivered to the IC pin depends on approach speed, humidity, temperature, etc., so it is difficult to obtain Typical Performance Curves repeatable results. The “E” device RS-562/232 pins withstand ±15kV air-gap discharges. CONTACT DISCHARGE TEST METHOD During the contact discharge test, the probe contacts the tested pin before the probe tip is energized, thereby eliminating the variables associated with the air-gap discharge. The result is a more repeatable and predictable test, but equipment limits prevent testing devices at voltages higher than ±8kV. All “E” family devices survive ±8kV contact discharges on the RS-562/232 pins.
