DESCRIPTION
The SP3222U and the SP3232U are 2 driver, 2 receiver RS-232 transceiver solutions
intended for portable or hand-held applications such as notebook or palmtop computers.
Their data transmission rate of 1000 kbps meets the demands of high speed RS-232
applications. Both ICs have a high-efficiency, charge-pump power supply that requires only
0.1µF capacitors in 3.3V operation. This charge pump allows the SP3222U and the 3232U
to deliver true RS-232 performance from a single power supply ranging from +3.0V to +5.5V.
The SP3222U device has a low-power shutdown mode where the devices' driver outputs and
charge pumps are disabled. During shutdown, the supply current falls to less than 1uA.

DESCRIPTION
active at 250kbps with RS-232 loads in parallel
with 1000pF capacitors. Figure 13 shows the
test results where one driver was active at
1000kbps and all drivers loaded with an RS-232
receiver in parallel with a 250pF capacitor.
The SP3222U and SP3232U are 2 driver/ 2re-
ceiver devices ideal for portable or hand-held
applications. The SP3222U features a 1µA
shutdown mode that reduces power consump-
tion and extends battery life in portable systems.
Its receivers remain active in shutdown mode,
allowing external devices such as modems to be
monitored using only 1 µA supply current.
The SP3222U driver's output stages are tristated
in shutdown mode. When the power is off, the
SP3222Udevicepermitstheoutputstobedriven
up to ±12V. Because the driver's inputs do not
have pull-up resistors, unused inputs should be
connected to VCC or GND.
TheSP3222U/3232UtransceiversmeettheEIA/
TIA-232 and V.28/V.24 communication proto-
cols They feature Sipex's proprietary on-board
charge pump circuitry that generates 2 x VCC for
RS-232 voltage levels from a single +3.0V to
+5.5V power supply. The SP3222U/3232U
drivers operate at a minimum data rate of
1000kbps.
In the shutdown mode, the supply current is less
than 1µA, where SHDN = LOW. When the
SP3222Udeviceisshutdown,thedevice'sdriver
outputs are disabled (tri-stated) and the charge
pumpsareturnedoffwithV+pulleddowntoVCC
and V- pulled to GND. The time required to exit
shutdown is typically 100µs. Connect SHDN to
VCC if the shutdown mode is not used.
THEORY OF OPERATION
Receivers
TheSP3222U/3232Useriesaremadeupofthree
basic circuit blocks: 1. Drivers, 2. Receivers,
and 3. the Sipex proprietary charge pump.
The receivers convert EIA/TIA-232 levels to
TTLorCMOSlogicoutputlevels. TheSP3222U
receivers have an inverting tri-state output. Re-
ceiver outputs (RxOUT) are tri-stated when the
enable control EN = HIGH. In the shutdown
mode, thereceiverscanbeactiveorinactive. EN
has no effect on TxOUT. The truth table logic of
the SP3222U driver and receiver outputs can be
found in Table 2.
Since receiver input is usually from a transmis-
sion line where long cable lengths and system
interference can degrade the signal and inject
noise, theinputshaveatypicalhysteresismargin
of 300mV. Should an input be left unconnected,
a 5kΩ pulldown resistor to ground will commit
the output of the receiver to a HIGH state.
Drivers
The drivers are inverting level transmitters that
convert TTL or CMOS logic levels to ±5.0V
EIA/TIA-232 levels inverted relative to the in-
put logic levels. Typically, the RS-232 output
voltage swing is ±5.5V with no load and at least
±5V minimum fully loaded. The driver outputs
are protected against infinite short-circuits to
groundwithoutdegradationinreliability. Driver
outputs will meet EIA/TIA-562 levels of ±3.7V
with supply voltages as low as 2.7V.

and C2 are initially charged to VCC. Cl+ is then
switched to GND and the charge in C1– is trans-
ferred to C2–. Since C2+ is connected to VCC, the
voltage potential across capacitor C2 is now 2
times VCC.
Charge Pump
The charge pump is a Sipex–patented design
(5,306,954) and uses a unique approach com-
paredtoolderless–efficientdesigns. Thecharge
pump still requires four external capacitors, but
uses a four–phase voltage shifting technique to
attain symmetrical 5.5V power supplies. The
internal power supply consists of a regulated
dual charge pump that provides output voltages
5.5V regardless of the input voltage (VCC) over
the +3.0V to +5.5V range.
Phase 2
— VSS transfer — Phase two of the clock con-
nects the negative terminal of C2 to the VSS
storage capacitor and the positive terminal of C2
to GND. This transfers a negative generated
voltage to C3. This generated voltage is regu-
lated to a minimum voltage of -5.5V. Simulta-
neous with the transfer of the voltage to C3, the
positive side of capacitor C1 is switched to VCC
and the negative side is connected to GND.
In most circumstances, decoupling the power
supplycanbeachievedadequatelyusinga0.1µF
bypass capacitor at C5 (refer to Figures 9 and
10). In applications that are sensitive to power-
supply noise, decouple VCC to ground with a
capacitor of the same value as charge-pump
capacitor C1. Physically connect bypass ca-
pacitors as close to the IC as possible.
Phase 3
— VDD charge storage — The third phase of the
clock is identical to the first phase — the charge
transferred in C1 produces –VCC in the negative
terminal of C1, which is applied to the negative
side of capacitor C2. Since C2+ is at VCC, the
voltage potential across C2 is 2 times VCC.
The charge pumps operate in a discontinuous
mode using an internal oscillator. If the output
voltages are less than a magnitude of 5.5V, the
charge pumps are enabled. If the output voltage
exceed a magnitude of 5.5V, the charge pumps
are disabled. This oscillator controls the four
phases of the voltage shifting. A description of
each phase follows.
Phase 4
— VDD transfer — The fourth phase of the clock
connects the negative terminal of C2 to GND,
and transfers this positive generated voltage
across C2 to C4, the VDD storage capacitor. This
voltage is regulated to +5.5V. At this voltage,
the internal oscillator is disabled. Simultaneous
withthetransferofthevoltagetoC4, thepositive
side of capacitor C1 is switched to VCC and the
negative side is connected to GND, allowing the
charge pump cycle to begin again. The charge
pump cycle will continue as long as the opera-
tional conditions for the internal oscillator are
present.
Phase 1

Since both V+ and V– are separately generated

that generate V– from V+ will show a decrease in
the magnitude of V– compared to V+ due to the
inherent inefficiencies in the design.

tors. ThismethodisalsospecifiedinMIL-STD-
883,Method3015.7forESDtesting.Thepremise
of this ESD test is to simulate the human body’s
potential to store electrostatic energy and
discharge it to an integrated circuit. The
simulation is performed by using a test model as
shown in Figure 20. This method will test the
IC’s capability to withstand an ESD transient
during normal handling such as in manufacturing
areas where the ICs tend to be handled
frequently.
ESD Tolerance
The SP3222U/3232U series incorporates
ruggedized ESD cells on all driver output and
receiver input pins. The ESD structure is
improved over our previous family for more
rugged applications and environments sensitive
to electrostatic discharges and associated tran-
sients.
For the Human Body Model, the current
limiting resistor (RS) and the source capacitor
(CS) are 1.5kΩ and 100pF, respectively.
The Human Body Model has been the generally
accepted ESD testing method for semiconduc-
