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 V_CCor 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 V_CCfor

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+pulleddowntoV_CC

and V- pulled to GND. The time required to exit

shutdown is typically 100µs. Connect SHDN to

V_CCif 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 C₂are initially charged to V_CC. C_l⁺is then

switched to GND and the charge in C₁^–is trans-

ferred to C₂^–. Since C₂⁺is connected to V_CC, the

voltage potential across capacitor C₂is now 2

times V_CC.

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 (V_CC) over

the +3.0V to +5.5V range.

Phase 2

— V_SStransfer — Phase two of the clock con-

nects the negative terminal of C₂to the V_SS

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 C₁is switched to V_CC

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 V_CCto 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

— V_DDcharge storage — The third phase of the

clock is identical to the first phase — the charge

transferred in C₁produces –V_CCin the negative

terminal of C₁, which is applied to the negative

side of capacitor C₂. Since C₂⁺is at V_CC, the

voltage potential across C₂is 2 times V_CC.

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

— V_DDtransfer — The fourth phase of the clock

connects the negative terminal of C₂to GND,

and transfers this positive generated voltage

across C₂to C₄, the V_DDstorage capacitor. This

voltage is regulated to +5.5V. At this voltage,

the internal oscillator is disabled. Simultaneous

withthetransferofthevoltagetoC₄, thepositive

side of capacitor C₁is switched to V_CCand 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.

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 (R_S) and the source capacitor

(C_S) are 1.5kΩ and 100pF, respectively.

The Human Body Model has been the generally

accepted ESD testing method for semiconduc-
