SP330E

RS-232/RS-485/RS-422 TRANSCEIVER WITH 1.65V-5.5V INTERFACE

November 2013

Rev. 1.0.0

FEATURES

GENERAL DESCRIPTION

 Robust ESD Protection:

The SP330 is an advanced multiprotocol transceiver

supporting RS-232, RS-485, and RS-422 serial

standards and featuring a variable low voltage logic

interface, down to 1.65V. Full operation requires only

four external charge pump capacitors.

■ ±15kV IEC 61000-4-2 Air Gap Discharge

■ ± 8kV IEC 61000-4-2 Contact Discharge

■ ±15kV Human Body Model (HBM)

 20Mbps RS-485 and 1Mbps RS-232 Data Rates

 Pin-Selectable 250kbps Slew Limiting

The RS-485/RS-232 mode pin selects RS-485 mode

when high, and RS-232 mode when low. In RS-485

mode the HALF/FULL pin configures the transceiver

as either half or full duplex.

 Single Supply Operation from +3V to +5.5V

 1.65V to 5.5V Logic Interface V pin

The high speed drivers operate up to 20Mbps in RS-

485/422 modes, and up to 1Mbps in RS-232 mode.

All drivers can be slew limited to 250kbps in any

mode to minimize electromagnetic interference (EMI)

by setting the dedicated SLEW pin low.

 2 Drivers, 2 Receivers RS-232/V.28

 1 Driver, 1 Receiver RS-485/422

■ Full or Half Duplex Configuration

■ 1/8th Unit Load, up to 256 receivers on bus

All transmitter outputs and receiver inputs feature

robust electrostatic discharge (ESD) protection to

±15kV IEC 61000-4-2 Airgap, ±15kV Human Body

Model (HBM) and ±8kV IEC 61000-4-2 Contact. Each

receiver output has full fail-safe protection to avoid

system lockup, oscillation, or indeterminate states by

defaulting to logic-high output level when the inputs

are open, shorted, or terminated but undriven. No

external biasing resistors are required.

 RS-485/422 Enhanced Receiver Fail-safe for open,

shorted, or terminated but idle inputs

 10nA Shutdown Supply Current (typical)

 Small 24 TSSOP package

The RS-232 receiver inputs include a 5k pull-down

to ground when in RS-232 mode. The RS-485/422

receiver inputs are high impedance (>96k), allowing

up to 256 devices on a single communication bus

(1/8th unit load).

The SP330 operates from a single power supply,

either 3.3V or 5V, with low idle current. The shutdown

mode consumes less than 1µA in low power standby

operation with RS-232 receivers enabled.

TYPICAL APPLICATIONS

 Software Programmable Serial Ports

(RS-232, RS-422, RS-485)

 Industrial and Single Board Computers

 Industrial and Process Control Equipment

 Point-Of-Sale Equipment

 HVAC Controls and Networking Equipment

 Building Security and Automation
