DESCRIPTION

The SP3222B/3232B series is an RS-232 transceiver solution intended for portable or hand-

held applications such as notebook or palmtop computers. The SP3222B/3232B series has

a high-efficiency, charge-pump power supply that requires only 0.1µF capacitors in 3.3V

operation. This charge pump allows the SP3222B/3232B series to deliver true RS-232

performance from a single power supply ranging from +3.0V to +5.5V. The ESD tolerance

of the SP3222B/3232B devices are over ±15kV for both Human Body Model and IEC1000-

4-2Airdischargetestmethods. TheSP3222Bdevicehasalow-powershutdownmodewhere

the devices' driver outputs and charge pumps are disabled. During shutdown, the supply

current falls to less than 1µA.

DESCRIPTION

Thedriverscanguaranteeadatarateof 250kbps

fully loaded with 3KΩ in parallel with 1000pF,

ensuring compatibility with PC-to-PC commu-

nication software.

TheSP3222B/3232BtransceiversmeettheEIA/

TIA-232 and V.28/V.24 communication proto-

cols and can be implemented in battery-pow-

ered, portable, or hand-held applications such

as notebook or palmtop computers. The

SP3222B/3232BdevicesallfeatureSipex'spro-

prietary 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.

This series is ideal for +3.3V-only systems,

mixed +3.3V to +5.5V systems, or +5.0V-only

systems that require true RS-232 performance.

The SP3222B/3232B series have drivers that

operate at a typical data rate of 250kbps fully

loaded.

The slew rate of the driver output is internally

limited to a maximum of 30V/µs in order to

meet the EIA standards (EIA RS-232D 2.1.7,

Paragraph 5). The transition of the loaded

output from HIGH to LOW also meets the

monotonicity requirements of the standard.

Figure 10 shows a loopback test circuit used to

the RS-232 drivers. Figure 11 shows the test

results of the loopback circuit with all drivers

active at 120kbps with RS-232 loads in parallel

with 1000pF capacitors. Figure 12 shows the

test results where one driver was active at

250kbps and all drivers loaded with an RS-232

receiver in parallel with a 1000pF capacitor. A

solid RS-232 data transmission rate of 250kbps

provides compatibility with many designs in

personal computer peripherals and LAN appli-

cations.

The SP3222B and SP3232B are 2-driver/2-

receiver devices ideal for portable or hand-held

applications. The SP3222B features a 1µA

shutdown mode that reduces power consump-

tionandextendsbatterylifeinportablesystems.

Its receivers remain active in shutdown mode,

allowing external devices such as modems to be

monitored using only 1µA supply current.

The SP3222B driver's output stages are turned

off (tri-state) when the device is in shutdown

mode. When the power is off, the SP3222B

device permits the outputs to be driven up to

±12V. The driver's inputs do not have pull-up

resistors. Designers should connect unused in-

puts to V_CCor GND.

THEORY OF OPERATION

The SP3222B/3232B series are made up of

three basic circuit blocks: 1. Drivers, 2.

Receivers, and 3. the Sipex proprietary charge

pump.

In the shutdown mode, the supply current falls

to less than 1µA, where SHDN = LOW. When

the SP3222B device is shut down, the device's

driver outputs are disabled (tri-stated) and the

charge pumps are turned off with V+ pulled

down to V_CCand V- pulled to GND. The time

required to exit shutdown is typically 100µs.

Connect SHDN to V_CCif the shutdown mode is

not used.

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.

In applications that are sensitive to power-sup-

ply noise, decouple V_CCto ground with a capaci-

tor of the same value as charge-pump capacitor

C1. Physically connect bypass capacitors as

close to the IC as possible.

Receivers

The receivers convert EIA/TIA-232 levels to

TTLorCMOSlogicoutputlevels. TheSP3222B

receivershaveaninvertingtri-stateoutput. These

receiver outputs (RxOUT) are tri-stated when

the enable control EN = HIGH. In the shutdown

mode, the receivers can be active or inactive.

EN has no effect on TxOUT. The truth table

logic of the SP3222B driver and receiver out-

puts can be found in Table 2.

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.

Since receiver input is usually from a transmis-

sion line where long cable lengths and system

interference can degrade the signal, the inputs

haveatypicalhysteresismarginof300mV. This

ensures that the receiver is virtually immune to

noisy transmission lines. Should an input be left

unconnected, a 5kΩ pulldown resistor to ground

will commit the output of the receiver to a HIGH

state.

Phase 1

— V_SScharge storage — During this phase of

the clock cycle, the positive side of capacitors

C₁and C₂are initially charged to V_CC. C_l⁺is

then switched to GND and the charge in C₁^–is

–

transferred to C₂. Since C₂⁺is connected to

V_CC, the voltage potential across capacitor C₂

is 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

bypasscapacitoratC5(refertoFigures8and9).

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.

This voltage is regulated to +5.5V. At this

voltage, the internal oscillator is disabled. Si-

multaneous with the transfer of the voltage to

C₄, the positive 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 operational conditions for the inter-

nal oscillator are present.

The Human Body Model has been the generally

accepted ESD testing method for semiconduc-

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 18. 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.

Since both V⁺and V^–are separately generated

from V_CC; in a no–load condition V⁺and V^–will

besymmetrical. Olderchargepumpapproaches

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.

For the Human Body Model, the current

limiting resistor (R_S) and the source capacitor

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

The clock rate for the charge pump typically

operatesat250kHz. Theexternalcapacitorscan

be as low as 0.1µF with a 16V breakdown

voltage rating.

ESD Tolerance

The SP3222B/3232B 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

transients.
