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.
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.
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 (3kand 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.
