ISL83384E ® Data Sheet March 15, 2005 ±15kV ESD Protected, +3V to +5.5V, 1 Microamp, 250Kbps, RS-232 Transmitter/Receiver FN6017.3 Features • ESD Protection for RS-232 I/O Pins to ±15kV (IEC61000) The Intersil ISL83384E contains 3.0V to 5.5V powered RS-232 transmitters/receivers which meet ElA/TIA-232 and V.28/V.24 specifications, even at VCC = 3.0V. 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 reduces 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. This device is fully compatible with 3.3V only systems, mixed 3.3V and 5.0V systems, and 5.0V only systems. The single pin powerdown function (SHDN = 0) disables all the transmitters and receivers, while shutting down the charge pump to minimize supply current drain.

Transmitter skew is measured at the transmitter zero crossing points. Detailed Description The ISL83384E 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 RS-232C and V.28 specifications. The circuit is divided into three sections: The charge pump, the transmitters, and the receivers. Charge-Pump Intersil’s new ISL83384E 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. 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 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. Transmitter inputs float if left unconnected (there are no pullup resistors), and may cause ICC increases. Connect unused inputs to GND for the best performance. TABLE 2. POWERDOWN AND ENABLE LOGIC TRUTH TABLE SHDN TRANSMITTER RECEIVER INPUT OUTPUTS OUTPUTS MODE OF OPERATION H Active Active Normal Operation L High-Z High-Z Manual Powerdown Receivers Transmitters The transmitters are proprietary, low dropout, inverting drivers that translate TTL/CMOS inputs to EIA/TIA-232 output levels. Coupled with the on-chip ±5.5V supplies, these transmitters deliver true RS-232 levels over a wide range of single supply system voltages. 4 The ISL83384E contains standard inverting receivers that three-state via the SHDN control line. Receivers driving powered down peripherals must be disabled to prevent current flow through the peripheral’s protection diodes (see Figures 2 and 3). FN6017.3 March 15, 2005 ISL83384E All the receivers convert RS-232 signals to CMOS output levels and accept inputs up to ±30V while presenting the required 3kΩ to 7kΩ input impedance (see Figure 1) even if the power is off (VCC = 0V). The receivers’ Schmitt trigger input stage uses hysteresis to increase noise immunity and decrease errors due to slow input signal transitions.

INVERTING RECEIVER CONNECTIONS Low Power Operation This 3V device requires a nominal supply current of 0.3mA, even at VCC = 5.5V, during normal operation (not in powerdown mode). This is considerably less than the 11mA current required by comparable 5V RS-232 devices, allowing users to reduce system power simply by replacing the old style device with the ISL83384E. FIGURE 2. POWER DRAIN THROUGH POWERED DOWN PERIPHERAL VCC TRANSITION DETECTOR Low Power, Pin Compatible Replacement Pin compatibility with existing 5V products (e.g., MAX222), coupled with the wide operating supply range, make the ISL83384E a potential lower power, higher performance drop-in replacement for existing 5V applications. As long as the ±5V RS-232 output swings are acceptable, and transmitter pull-up resistors aren’t required, the ISL83384E should work in most 5V applications. When replacing a device in an existing 5V application, it is acceptable to terminate C3 to VCC as shown on the “Typical Operating Circuit”. Nevertheless, terminate C3 to GND if possible, as slightly better performance results from this configuration. TO WAKE-UP LOGIC ISL83384E V- VCC RX POWERED DOWN UART VOUT = HI-Z TX FIGURE 3. DISABLED RECEIVERS PREVENT POWER DRAIN Powerdown Functionality The already low current requirement drops significantly when the device enters powerdown mode. In powerdown, supply current drops to 1µA, because the on-chip charge pump turns off (V+ collapses to VCC, V- collapses to GND), and the transmitter and receiver outputs three-state. This micro-power mode makes these devices ideal for battery powered and portable applications. SHDN PWR MGT LOGIC ISL83384E Software Controlled (Manual) Powerdown The ISL83384E may be forced into its low power, standby state via a simple shutdown (SHDN) pin (see Figure 4). Driving this pin high enables normal operation, while driving it low forces the IC into its powerdown state. The time required to exit powerdown, and resume transmission is less than 50µs. Connect SHDN to VCC if the powerdown function isn’t needed. I/O UART CPU FIGURE 4. CONNECTIONS FOR MANUAL POWERDOWN 5 FN6017.3 March 15, 2005 ISL83384E Capacitor Selection High Data Rates The charge pumps require 0.1µF or greater capacitors for operation with 3.3V ≤ 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). The ISL83384E maintains the RS-232 ±5V minimum transmitter output voltages even at high data rates. Figure 6 details a transmitter loopback test circuit, and Figure 7 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 8 shows the loopback results for a single transmitter driving 1000pF and an RS-232 load at 250Kbps. The static transmitter was also loaded with an RS-232 receiver. 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-. VCC + 0.1µF + C1+ VCC V+ + C3 C1 Operation Down to 2.7V C1- ISL83384E 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. ISL83384E + TIN Transmitter Outputs when Exiting Powerdown C4 + C2- Power Supply Decoupling In most circumstances a 0.1µF bypass capacitor is adequate. 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. V- C2+ C2 TOUT 1000pF RIN ROUT 5K VCC SHDN FIGURE 6. TRANSMITTER LOOPBACK TEST CIRCUIT Figure 5 shows the response of two transmitter outputs when exiting powerdown mode. As they activate, the two transmitter outputs properly go to opposite RS-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. 5V/DIV T1IN T1OUT 5V/DIV SHDN T1 R1OUT VCC = +3.3V C1 - C4 = 0.1µF 5µs/DIV 2V/DIV FIGURE 7.

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 IC’s 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-232 pins on “E” family devices can withstand HBM ESD events to ±15kV.

LOOPBACK TEST AT 250Kbps Interconnection with 3V and 5V Logic The ISL83384E directly interfaces with 5V CMOS and TTL logic families. Nevertheless, with the device at 3.3V, and the logic supply at 5V, AC, HC, and CD4000 outputs can drive ISL83384E inputs, but ISL83384E outputs do not reach the minimum VIH for these logic families. See Table 3 for more information. TABLE 3. LOGIC FAMILY COMPATIBILITY WITH VARIOUS SUPPLY VOLTAGES VCC SYSTEM POWER-SUPPLY SUPPLY VOLTAGE VOLTAGE (V) (V) 3.3 3.3 5 5 5 3.3 COMPATIBILITY Compatible with all CMOS families. Compatible with all TTL and CMOS logic families. Compatible with ACT and HCT CMOS, and with TTL. ISL83384E outputs are incompatible with AC, HC, and CD4000 CMOS inputs. ±15kV ESD Protection 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-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 storage capacitor yields a test that is much more severe than the HBM test. The extra ESD protection built into this device’s RS-232 pins allows the design of equipment meeting level 4 criteria without the need for additional board level protection on the RS-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 repeatable results. The “E” device RS-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-232 pins. All pins on ISL83XXX devices include ESD protection structures, but the ISL83384E incorporates advanced structures which allow the RS-232 pins (transmitter outputs and receiver inputs) to survive ESD events up to ±15kV. The RS-232 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-232 signals as large as ±25V. 7 FN6017.3 March 15, 2005 ISL83384E Typical Performance Curves VCC = 3.3V, TA = 25°C 25 VOUT+ 4.0 20 SLEW RATE (V/µs) TRANSMITTER OUTPUT VOLTAGE (V) 6.0 2.0 1 TRANSMITTER AT 250Kbps 1 TRANSMITTER AT 30Kbps 0 -2.0 15 -SLEW +SLEW 10 VOUT - -4.0 -6.0 0 1000 2000 3000 4000 5 5000 0 1000 FIGURE 9.
