Texas Instruments Announces Industry's First 3.3-V CAN Transceivers
New Robust CAN Solutions Reduce Power Consumption and System Cost in Motor and Motion Control Applications
DALLAS (March 26, 2001) -- Enabling lower power, cost and space savings for manufacturers of industrial and automotive control systems, Texas Instruments Incorporated (TI) (NYSE: TXN) today announced the industry's first family of 3.3-volt (V) transmitter-receivers for the Controller Area Network (CAN). The new HVD23x CAN family of transceivers reduces the need for an additional 5-V power supply when used as bus interfaces for 3.3-V micro-controllers and digital signal processors (DSPs), including TI's new 3.3V TMS320LF2403A DSP, also announced today. Manufacturers of industrial and automotive control systems using the robust CAN bus will benefit from the lower power, space savings and reduced bill of materials made possible by this new family of devices.

Flexibility and Efficiency
The SN65HVD23x CAN Data Line Transceiver family is designed for flexibility in implementing reliable, efficient bi-directional data transfer among controllers. Compliant with the ISO 11898 standard for the CAN bus architecture, the transceivers support differential signaling at speeds up to 1 megabit per second (Mbps), providing compatibility with existing signaling schemes. The devices are available in the industry-standard PCA82C250 footprint for double-terminated lines and half-duplex operation, saving time to market by providing a drop-in low-power replacement for existing components.
The first available device in the family, the SN65HVD230, features a programmable output transistion time, or slew rate control, helping designers minimize electromagnetic interference (EMI), for greater system reliability. The SN65HVD230 also features an ultra low-current standby mode to minimize power consumption while monitoring bus activity during idle periods. A device scheduled for release in 3Q01, the SN65HVD231, offers programmable slope control and a full-sleep mode to reduce power consumption even more. Another device to be released later this year, the SN65HVD232, offers greater cost-efficiency without slew rate control, standby mode or sleep mode.
"As control intelligence rapidly spreads throughout the industrial market and replaces centralized system with smart peripherals, designers need low-power options to help them implement the robust CAN bus," said Veronica Valdivia, WW interface product marketing manager, TI. "The release of the 3.3-V SN65HVD23x CAN transceiver and the TMS320LF2403A DSP family is part of TI's strategy to provide complete DSP solutions for motor and motion control."
Industrial systems are increasingly being controlled by DSPs, which provide high real-time performance and low power consumption affordably for more efficient system operation. The CAN bus, designed for and tested in the rigorous automotive environment, offers robust communications among subsystems in industrial equipment. The low-power SN65HVD23x transceivers help implement the CAN by directly supporting DSPs such as TI's new TMS320LF2403A DSP with integrated CAN controller, as well as a wide variety of microcontrollers and other control logic. Applications that can benefit include AC and DC motors, robotics, process control, intelligent sensors, multiple-motor equipment and automotive systems.
About the TMS320LF2403A DSP
TI's new programmable DSP aimed at demanding, space-constrained applications, enables reliable, compact and cost-effective solutions. By providing 16K words of Flash memory with code security, 1K word of RAM, a 10-bit ADC with eight input channels, an Event manager, a 2.0B compliant CAN Controller, SPI and 21 GPIOs, the LF2403A DSP controller enables consumer and industrial original equipment manufactures (OEMs) to create more compact, intelligent and robust product designs.
TI customers who are designing applications with the LF2403A and related products have the industry's most sophisticated DSP controller support available. For programmers who are new to DSP, TI support helps simplify the process of writing and debugging code, enabling developers to be more innovative and productive much faster. Support includes TI's eXpressDSP™ Real-Time Software Technology, complete with the Code Composer Studio™ integrated development environment (IDE), the industry's most sophisticated DSP IDE, and the largest network of DSP third-party developers in the industry. In addition, customers can rely on TI's motor control foundation software, which provides ready-made algorithms that speed development and reduce time to market.
Availability, Packaging and Pricing
The SN65HVD230 CAN Data Line Transceiver is sampling now, with volume production scheduled for the second quarter of 2001. Availability of the SN65HVD231 and SN65HVD232 transceivers is scheduled for the third quarter. Each of the SN65HVD23x devices is available in an 8-pin small outline integrated circuit (SOIC) package. Planned in quantities of 1,000, the SN65HVD230 is $1.92, the SN65HVD231 is $1.92, and the SN65HVD232 is $1.75.
