Data Sheet March 1, 2006 FN4805.21
One Microamp Supply-Current, +3V to +5.5V, 250kbps, RS-232 Transmitters/Receivers
The Intersil ICL32XX 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. 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 powerdown functions (except for the ICL3232), 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 3.3V only systems, mixed 3.3V and 5.0V systems, and 5.0V only systems. The ICL324X are 3-driver, 5-receiver devices that provide a complete serial port suitable for laptop or notebook computers. Both devices also include noninverting alwaysactive receivers for "wake-up" capability. The ICL3221, ICL3223 and ICL3243, feature an automatic powerdown 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 ICL32XX 3V family.

ICL3221, ICL3222, ICL3223, ICL3232, ICL3241, ICL3243 Detailed Description
ICL32XX 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. The ICL3221/22/23/41 inverting receivers disable only when EN is driven high. ICL3243 receivers disable during forced (manual) powerdown, but not during automatic powerdown (See Table 2). ICL324X monitor receivers remain active even during manual powerdown 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.

Charge-Pump
Intersil's new ICL32XX family 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 0.1F capacitors for the voltage doubler and inverter functions at VCC = 3.3V. See the Capacitor Selection section, and Table 3 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.
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 powerdown 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.
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. Except for the ICL3232, 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 (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.
Pin Compatible Replacements For 5V Devices
The ICL3221/22/32 are pin compatible with existing 5V RS-232 transceivers - see the Features section on the front page for details. This pin compatibility coupled with the low Icc and wide operating supply range, make the ICL32XX 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 ICL32XX 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.
Receivers
All the ICL32XX devices contain standard inverting receivers that three-state (except for the ICL3232) via the EN or FORCEOFF control lines. Additionally, the two ICL324X 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. 10
Powerdown Functionality (Except ICL3232)
The already low current requirement drops significantly when the device enters powerdown mode. In powerdown, 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 powerdown; refer to Table 2 for details. This micro-power mode makes these devices ideal for battery powered and portable applications.

Software Controlled (Manual) Powerdown
Most devices in the ICL32XX family provide pins that allow the user to force the IC into the low power, standby state. On the ICL3222 and ICL3241, the powerdown control is 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 2 and 3). The ICL3221, ICL3223, and ICL3243 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 powerdown 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 powerdown circuitry. ICL3243 inverting (standard) receiver outputs also disable when the device is in manual powerdown, thereby eliminating the possible current path through a shutdown peripheral's input protection diode (See Figures 2 and 3).

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 powerdown feature, enabling them to function as a manual SHUTDOWN input (See Figure 4).

With any of the above control schemes, the time required to exit powerdown, and resume transmission is only 100s. A mouse, or other application, may need more time to wake up from shutdown. If automatic powerdown is being utilized, the RS-232 device will reenter powerdown if valid receiver levels aren't reestablished within 30s of the ICL32XX powering up. Figure 5 illustrates a circuit that keeps the ICL32XX from initiating automatic powerdown for 100ms after powering up. This gives the slow-to-wake peripheral circuit time to reestablish valid RS-232 output levels.

Even greater power savings is available by using the devices which feature an automatic powerdown function. When no valid RS-232 voltages (See Figure 6) are sensed on any receiver input for 30s, the charge pump and transmitters powerdown, 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 ICL32XX powers back up whenever it detects a valid RS-232 voltage level on any receiver input. This automatic powerdown feature provides additional system power savings without changes to the existing operating system.

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.
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 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-.

FIGURE 6. DEFINITION OF VALID RS-232 RECEIVER LEVELS
Automatic powerdown operates when the FORCEON input is low, and the FORCEOFF input is high. Tying FORCEON high disables automatic powerdown, but manual powerdown is always available via the overriding FORCEOFF input. Table 2 summarizes the automatic powerdown functionality. Devices with the automatic powerdown 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 powerdown, or forced on), so it is also useful for systems employing manual powerdown circuitry. When automatic powerdown is utilized, INVALID = 0 indicates that the ICL32XX is in powerdown mode.

Power Supply Decoupling
In most circumstances a 0.1F 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.

ICL32XX 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 Powerdown
Figure 8 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 3k in parallel with 2500pF. Note that the transmitters enable only when the magnitude of the supplies exceed approximately 3V.
The time to recover from automatic powerdown mode is typically 100s.
Receiver ENABLE Control (ICL3221/22/23/41 Only)
