Features
• Pb-free Available as an Option (see Ordering Info)
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 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 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.

- ISDN Terminal Adaptors and Set Top Boxes
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.

Detailed Description
Transmitters
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 0.1µF 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.
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.
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 0.1µF 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
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 (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 800kbps.
Transmitter inputs float if left unconnected, and may cause
ICC increases. Connect unused inputs to GND for the best
performance.
ICL3207, ICL3217
Receivers
VCC
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 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.
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

from this configuration.

PERIPHERAL
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.
6
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 30µs, the ICL3217 automatically
enters its powerdown state (see Figure 5). 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 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 100µs.

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 0.1µF 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.

FIGURE 5. AUTOMATIC POWERDOWN TIMING DIAGRAM
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.
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 3kΩ in parallel with 2500pF.
Note that the transmitters enable only when the magnitude
of the supplies exceed approximately 3V.

Capacitor Selection
The charge pumps require 0.1µF, or greater, capacitors for
3.3V operation. With 0.1µF 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,
0.22µF capacitors are recommended (see Table 3). Existing
5V applications typically utilize either 0.1µF or 1µF
capacitors, and the ICL32X7E works well with either value.
New 5V designs should use 0.22µF 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.
