DATASHEET ICL3221E, ICL3222E, ICL3223E, ICL3232E, ICL3241E, ICL3243E The Intersil ICL32xxE devices are 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. Additionally, they provide 15kV ESD protection (IEC61000-4-2 Air Gap and Human Body Model) on transmitter outputs and receiver inputs (RS232 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 manual and automatic power-down functions (except for the ICL3232E), reduce the standby supply current to a 1A 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 family is fully compatible with 3.3Vonly systems, mixed 3.3V and 5.0V systems, and 5.0V-only systems. The ICL324XE are 3-driver, 5-receiver devices that provide a complete serial port suitable for laptop or notebook computers. Both devices also include noninverting always-active receivers for "wake-up" capability. The ICL3221E, ICL3223E and ICL3243E, feature an automatic power-down function which powers down the on-chip power-supply and driver circuits. This occurs when an attached peripheral device is shut off or the RS-232 cable is removed, conserving system power automatically without changes to the hardware or operating system. These devices power up again when a valid RS-232 voltage is applied to any receiver input. Table 1 summarizes the features of the devices represented by this data sheet, while Application Note AN9863 summarizes the features of each device comprising the ICL32xxE 3V family.

Detailed Description ICL32xxE interface ICs operate from a single +3V to +5.5V supply, guarantee a 250kbps minimum data rate, require only four small external 0.1F capacitors, feature low power consumption, and meet all ElA RS-232C and V.28 specifications. The circuit is divided into three sections: charge pump, transmitters and receivers. Charge-Pump Intersil's new ICL32xxE family utilizes regulated onchip 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 0.1F capacitors for the voltage doubler and inverter functions at VCC = 3.3V. See "Capacitor Selection" on page 18 and Table 3 on page 18 for capacitor recommendations for other operating conditions. 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-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. FN4910 Rev 22.00 December 9, 2015 Except for the ICL3232E, all transmitter outputs disable and assume a high impedance state when the device enters the power-down mode (see Table 2). These outputs may be driven to 12V when disabled. All devices guarantee a 250kbps data rate for full load conditions (3k and 1000pF), VCC 3.0V, with one transmitter operating at full speed. Under more typical conditions of VCC 3.3V, RL = 3k, and CL = 250pF, one transmitter easily operates at 900kbps. Transmitter inputs float if left unconnected, and may cause ICC increases. Connect unused inputs to GND for the best performance. Receivers All the ICL32xxE devices contain standard inverting receivers that three-state (except for the ICL3232E) via the EN or FORCEOFF control lines. Additionally, the two ICL324XE products include noninverting (monitor) receivers (denoted by the ROUTB label) that are always active, regardless of the state of any control lines. All the receivers convert RS-232 signals to CMOS output levels and accept inputs up to 25V while presenting the required 3k to 7k 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. The ICL3221E, ICL3222E, ICL3223E, ICL3241E inverting receivers disable only when EN is driven high. ICL3243E receivers disable during forced (manual) power-down, but not during automatic power-down (see Table 2). Page 14 of 33 ICL3221E, ICL3222E, ICL3223E, ICL3232E, ICL3241E, ICL3243E ICL3241E and ICL3243E monitor receivers remain active even during manual power-down and forced receiver disable, making them extremely useful for Ring Indicator monitoring. Standard receivers driving powered down peripherals must be disabled to prevent current flow through the peripheral's protection diodes (see Figures 2 and 3). This renders them useless for wake up functions, but the corresponding monitor receiver can be dedicated to this task as shown in Figure 3. VCC RXIN -25V VRIN +25V RXOUT GND VROUT VCC 5k GND FIGURE 1. INVERTING RECEIVER CONNECTIONS Low Power Operation These 3V devices require a nominal supply current of 0.3mA, even at VCC = 5.5V, during normal operation (not in power-down mode). This is considerably less than the 5mA to 11mA current required by comparable 5V RS-232 devices, allowing users to reduce system power simply by switching to this new family. Pin Compatible Replacements for 5V Devices The ICL3221E, ICL3222E, ICL3232E are pin compatible with existing 5V RS-232 transceivers - See the "Features" section on page 1 for details. This pin compatibility coupled with the low ICC and wide operating supply range, make the ICL32xxE potential lower power, higher performance drop-in replacements for existing 5V applications. As long as the 5V RS-232 output swings are acceptable, and transmitter input pull-up resistors aren't required, the IICL32xxE 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 Circuits" on page 2. Nevertheless, terminate C3 to GND if possible, as slightly better performance results from this configuration. Power-Down Functionality (Except ICL3232E) The already low current requirement drops significantly when the device enters power-down mode. In power-down, supply current drops to 1A, because the on-chip charge pump turns off (V+ collapses to VCC, V- collapses to GND), and the transmitter outputs three-state. Inverting receiver outputs may or may not disable in power-down; refer to Table 2 for details. This micro-power mode makes these devices ideal for battery powered and portable applications. Software Controlled (Manual) Power-Down Most devices in the ICL32xxE family provide pins that allow the user to force the IC into the low power, standby state. On the ICL3222E and ICL3241E, the power-down control is via a simple shutdown (SHDN) pin. Driving this pin high enables normal operation, while driving it low forces the IC into its power-down state. Connect SHDN to VCC if the power-down function isn't needed. Note that all the receiver outputs remain enabled during shutdown (see Table 2). For the lowest power consumption during power-down, the receivers should also be disabled by driving the EN input high (see next section, and Figures 2 and 3). The ICL3221E, ICL3223E, and ICL3243E utilize a two pin approach where the FORCEON and FORCEOFF inputs determine the IC's mode. For always enabled operation, FORCEON and FORCEOFF are both strapped high. To switch between active and power-down modes, under logic or software control, only the FORCEOFF input need be driven. The FORCEON state isn't critical, as FORCEOFF dominates over FORCEON. Nevertheless, if strictly manual control over powerdown is desired, the user must strap FORCEON high to disable the automatic power-down circuitry. ICL3243E inverting (standard) receiver outputs also disable when the device is in manual power-down, thereby eliminating the possible current path through a shutdown peripheral's input protection diode (see Figures 2 and 3).

Applies only to the ICL3241E and ICL3243E. The INVALID output always indicates whether or not a valid RS-232 signal is present at any of the receiver inputs (see Table 2), giving the user an easy way to determine when the interface block should power down. In the case of a disconnected interface cable where all the receiver inputs are floating (but pulled to GND by the internal receiver pull down resistors), the INVALID logic detects the invalid levels and drives the output low. The power management logic then uses this indicator to power down the interface block. Reconnecting the cable restores valid levels at the receiver inputs, INVALID switches high, and the power management logic wakes up the interface block. INVALID can also be used to indicate the DTR or RING INDICATOR signal, as long as the other receiver inputs are floating, or driven to GND (as in the case of a powered down driver). Connecting FORCEOFF and FORCEON together disables the automatic power-down feature, enabling them to function as a manual SHUTDOWN input (see Figure 4).

CIRCUIT TO PREVENT AUTO POWER-DOWN FOR 100ms AFTER FORCED POWER-UP Automatic Power-Down (ICL3221E, ICL3223E, ICL3243E Only) Even greater power savings is available by using the devices which feature an automatic power-down function. When no valid RS-232 voltages (see Figure 6) are sensed on any receiver input for 30s, the charge pump and transmitters power-down, thereby reducing supply current to 1A. Invalid receiver levels occur whenever the driving peripheral's outputs are shut off (powered down) or when the RS-232 interface cable is disconnected. The ICL32xxE powers back up whenever it detects a valid RS-232 voltage level on any receiver input. This automatic power-down feature provides additional system power savings without changes to the existing operating system. 2.7V INDETERMINATE - POWER-DOWN MAY OR MAY NOT OCCUR I/O UART CPU VALID RS-232 LEVEL - ICL32xxE IS ACTIVE 0.3V INVALID LEVEL - POWER-DOWN OCCURS AFTER 30s -0.3V INDETERMINATE - POWER-DOWN MAY OR MAY NOT OCCUR FIGURE 4. CONNECTIONS FOR MANUAL POWER-DOWN WHEN NO VALID RECEIVER SIGNALS ARE PRESENT With any of the control schemes, the time required to exit power-down, and resume transmission is only 100s. A mouse, or other application, may need more time to wake up from shutdown. If automatic power-down is being utilized, the RS-232 device will reenter power-down if valid receiver levels aren't reestablished within 30s of the ICL32xxE powering up. Figure 5 illustrates a circuit that keeps the ICL32xxE from initiating automatic power-down for 100ms after powering up. This gives the slow-to-wake peripheral circuit time to reestablish valid RS-232 output levels. FN4910 Rev 22.00 December 9, 2015 -2.7V VALID RS-232 LEVEL - ICL32xxE IS ACTIVE FIGURE 6. DEFINITION OF VALID RS-232 RECEIVER LEVELS Automatic power-down operates when the FORCEON input is low, and the FORCEOFF input is high. Tying FORCEON high disables automatic power-down, but manual power-down is always available via the overriding FORCEOFF input. Table 2 summarizes the automatic power-down functionality. Page 17 of 33 ICL3221E, ICL3222E, ICL3223E, ICL3232E, ICL3241E, ICL3243E Devices with the automatic power-down feature include an INVALID output signal, which switches low to indicate that invalid levels have persisted on all of the receiver inputs for more than 30s (see Figure 7). INVALID switches high 1s after detecting a valid RS-232 level on a receiver input. INVALID operates in all modes (forced or automatic power-down, or forced on), so it is also useful for systems employing manual power-down circuitry. When automatic power-down is utilized, INVALID = 0 indicates that the ICL32xxE is in power-down mode. The time to recover from automatic power-down mode is typically 100s.

AUTOMATIC POWER-DOWN AND INVALID TIMING DIAGRAMS Receiver ENABLE Control (ICL3221E, ICL3222E, ICL3223E, ICL3241E Only) Several devices also feature an EN input to control the receiver outputs. Driving EN high disables all the inverting (standard) 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 2). The enable input has no effect on transmitter nor monitor (ROUTB) outputs. ICL32xxE transmitter outputs meet RS-562 levels (3.7V), at full data rate, with VCC as low as 2.7V. RS-562 levels typically ensure interoperability with RS-232 devices. Transmitter Outputs when Exiting Power-Down Figure 8 shows the response of two transmitter outputs when exiting power-down 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 3kin parallel with 2500pF. Note that the transmitters enable only when the magnitude of the supplies exceed approximately 3V.. 5V/DIV FORCEOFF T1 2V/DIV Capacitor Selection The charge pumps require 0.1F capacitors for 3.3V operation. For other supply voltages refer to Table 3 for capacitor values. Do not use values smaller than those listed in Table 3. 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 FN4910 Rev 22.00 December 9, 2015 T2 VCC = +3.3V C1 - C4 = 0.1F TIME (20s/DIV) FIGURE 8.

The on-chip switching regulator ensures the transmitters will supply at least 5V during worst case conditions (15mA for paralleled V+ transmitters, 7.3mA for single Vtransmitter).

ICL32XX outputs are incompatible with AC, HC, and CD4000 CMOS inputs. 15kV ESD Protection All pins on ICL32XX devices include ESD protection structures, but the ICL32xxE family 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 latch-up mechanism to activate, and don't interfere with RS-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 1.5k current limiting resistor, making the test less severe than the IEC61000 test which utilizes a 330 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. Typical Performance Curves IEC61000-4-2 Testing 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.
