Sipex Announces Low Voltage, High Speed RS232 Transceiver for Wireless Connectivity



(Milpitas, CA - March 22, 2004) - Sipex Corporation (NASDAQ:SIPX), a leading provider of high performance, analog integrated circuits (ICs), today introduced a new 3V RS232 transceiver, the SP3282EB. The device includes 5 drivers and 3 receivers for support of all modem handshake signals used in standard PC-modem software. A high serial data rate of 250Mbps enables users to enjoy the full download speeds available in advanced wireless networks such as GPRS, EDGE or CDMA2000. The SP3282EB is an ideal solution for PC to cell phone data cables used to upload or download data, photos or music and for wireless handhelds with a high-speed internet modem.

The SP3282EB offers robust ESD protection on both the RS232 pins and CMOS/TTL-logic pins. The device's enhanced ESD rating on all I/O pins protects the device to ±15kV Human Body Model, ±15kV IEC 1000-4-2 Air Discharge and ±8kV IEC 1000-4-2 Contact Discharge.

The SP3282EB operates from a single +2.35V to 5.5V voltage supply range. Intelligent onboard charge pumps generate full RS232 driver outputs down to 3.1V and RS232-compatible outputs down to +2.35V. This wide supply voltage range allows the device to be powered directly off unregulated Lithium-Ion batteries. A special VL pin controls the logic input and output levels, thus eliminating the need for external translators to interoperate with logic levels from 5.5V to 1.8V.

SP3282EB Key Features (Typical):

o 5 Drivers and 3 Receivers, complete modem serial port on a chip

o High ESD Protection on RS232 and CMOS/TTL Pins

o Enhanced ESD protection: ±15kV Human Body Model, ±15kV IEC 1000-4-2 Air Discharge, and ±8kV IEC1000-4-2 Contact Discharge

o Data rate of 250Kbps

o Operates directly off of Li-Ion Battery

o Unique VL pin allows for interoperation of mixed logic voltage systems

Pricing and Availability

SP3282EB is available now in 28-pin TSSOP and SSOP packages and priced at $2.30 in 1,000 piece quantities.
