Data Sheet October 20, 2005 FN4892.6
Low Power, +3V to +5.5V, 250kbps, RS-232 Transmitters/Receivers
The Intersil ICL32X7 devices are 3.0V to 5.5V powered RS-232 transmitters (five)/receivers (three) which meet ElA/TIA-232 and V.28/V.24 specifications, even at VCC = 3.0V. Targeted applications are ISDN Terminal Adaptors, PDAs, Palmtops, peripherals, and notebook and laptop computers where the low operational, and even lower standby, power consumption is critical. The ICL3217's efficient on-chip charge pumps, coupled with an automatic powerdown function, reduces 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, and is a lower power, pin-for-pin replacement for `207 and `237 type devices. The ICL3217 features 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. The ICL3217 powers 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.

Detailed Description
The ICL32X7 interface ICs operate from a single +3V to +5.5V power 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: The charge pump, the transmitters, and the 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. ICL3217 transmitter outputs disable and assume a high impedance state when the device enters the automatic powerdown mode. These outputs may be driven to 12V when disabled. Both 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 800kbps. Transmitter inputs float if left unconnected, and may cause ICC increases. Connect unused inputs to GND for the best performance.
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. 5
ICL3207, ICL3217
Receivers
The ICL32X7 each contain inverting receivers that 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. Receivers on the ICL3207 are always active. The ICL3217 receivers disable when in the automatic powerdown state, thereby eliminating the possible current path through a shutdown peripheral's input protection diode (see Figures 2 and 3).

When replacing a `207 or `237 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.

Automatic Powerdown (ICL3217 Only)
Even greater power savings is available by using the ICL3217 which features an automatic powerdown function. When no valid RS-232 voltages (see Figure 4) are sensed on any receiver input for 30s, the ICL3217 automatically enters its powerdown state (see Figure 5). 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 receiver and transmitter outputs three-state (see Table 2). This micro-power mode makes the ICL3217 ideal for battery powered and portable applications. 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 ICL3217 powers back up whenever it detects a valid RS-232 voltage level on any receiver input (such as when the RS-232 cable is reconnected). The time to recover from automatic powerdown mode is typically 100s.

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 11mA current required by comparable 5V RS-232 devices, allowing users to reduce system power simply by replacing the old style device with the ICL3207.
Low Power, Pin Compatible Replacement
Pin compatibility with existing 5V products (e.g., MAX207), coupled with the wide operating supply range, make the ICL32X7 potential lower power, higher performance drop-in replacements for existing `2X7 5V applications. As long as the 5V RS-232 output swings are acceptable, the ICL32X7 devices should work in most 5V applications.

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-.

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.
FIGURE 5. AUTOMATIC POWERDOWN TIMING DIAGRAM
Transmitter Outputs when Exiting Powerdown
Figure 6 shows the response of two ICL3217 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.
.
This automatic powerdown feature provides additional system power savings without changes to the existing operating system or hardware. Utilizing power management circuitry, to power down the rest of the communication circuitry (e.g., the UART) when the ICL3217 powers down, produces even greater power savings. Connecting a transition detector to the V- pin (see Figure 3) is an easy way for the power management logic to determine when the ICL3217 enters and exits powerdown.

Capacitor Selection
The charge pumps require 0.1F, or greater, capacitors for 3.3V operation. With 0.1F capacitors, five percent tolerance supplies (e.g., 3.14V minimum) deliver greater than 5V transmitter swings at full data rate, while ten percent tolerance supplies (e.g., 2.97V minimum) deliver 4.95V transmitter swings. If greater than 5V transmitter swings are required with a ten percent tolerance 3.3V supply, 0.22F capacitors are recommended (see Table 3). Existing 5V applications typically utilize either 0.1F or 1F capacitors, and the ICL32X7E works well with either value. New 5V designs should use 0.22F capacitors for the best results. For other supply voltages refer to Table 3 for capacitor values. Do not use values smaller than those listed

The ICL32XX maintain 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.
