TI's Three New Programmable DSPs Combine Simplicity and Performance Enabling Breakthrough Digital Control Designs
New Devices Give OEMs the Freedom to Develop More Compact, Intelligent and Robust Digital Control Applications like Digital Appliances, Electronic Cooling Systems and Intelligent Sensors
HOUSTON (March 26, 2001) -- Enabling the next level of performance in space-constrained digital control applications, Texas Instruments (TXN) today announced three new digital signal processing (DSP) devices, including the industry's smallest programmable DSP controller. These devices enable consumer and industrial original equipment manufacturers (OEMs) to create more compact, intelligent and robust product designs while decreasing system costs. See http://www.dspvillage.ti.com/lf2401a
TI's programmable TMS320LF2401A DSP controller is designed for applications where space savings and real-time performance are both critical design requirements. A high level of system integration and the industry's smallest DSP controller package combine with the excellent performance and price of the LF2401A to help OEMs bring control products to market faster. TI has successfully integrated a 40 MIPS DSP core, Flash memory and a suite of control-optimized peripherals into its smallest device, a package that is no larger than the size of a contact lens. This device will also offer five times the performance per square area over the competition, providing increased capabilities for more differentiated designs.
Application areas that will benefit from this revolutionary DSP include handheld power tools, electronic cooling systems, tunable lasers, intelligent sensors, appliances and a wide variety of other control-oriented equipment. Additionally, consumer goods ranging from toys to training systems will benefit from this small, performance-packed DSP.
"TI's new TMS320C2000™ DSP controllers are perfect when designing in small spaces as we do with our model trains," said Dave Krebiehl, vice president of research and market development, MTH Electric Trains. "With the performance and integrated features of TI DSPs, we have delivered the most authentic sounds and control features in the history of model trains."
System integration in a small package
Operating at 3.3-volts (V), the LF2401A controller features 8K words of Flash memory with code security, which is divided into two 4K-word sectors. With Flash memory, designers are able to rapidly develop new products and have the freedom to reprogram their system in the field. Also available are 1K words of on-chip random access memory (RAM), as well as read-only memory (ROM) for boot-up into Flash memory. Key peripherals include an ultra-fast 10-bit, five-channel analog-to-digital converter (ADC), Event Manager, a serial communications interface (SCI), Watchdog Timer and 13 general-purpose input/output (GPIO) channels. This highly integrated device is packaged in a tiny 7mm X 7mm low-profile quad flatpack (LQFP) that is 3X smaller than the 28-pin SOIC, a low pin-count package that is commonly used in many space-constrained applications today.
"TI is a leader in driving intelligent digital control to new levels of performance and integration, and I am impressed with their foresight on what the market is looking for," said George Gulalo, president, Motion Tech Trends. "With the small size of TI's new TMS320LF2401A, many designers will now have the opportunity to explore new possibilities in previously untapped control markets."
The size and performance of the programmable LF2401A is key to the success of many next-generation control applications. For example, real-time DSP control enables sensorless variable-speed operation and accurate control in power tools, appliances, toys and a wide variety of other applications. Sensors of all types become much more intelligent when designed around the integrated peripherals of the LF2401A. With the small package size, controllers can be mounted in small motors such as those in electronic cooling systems for telecom equipment, making the designs more reliable, compact and cost-effective.
TI's programmable LF2401A offers 40 million instructions per second (MIPS) for only $5.95, offering the best price/performance ratio of any Flash DSP controller available.
Other new DSP control devices from TI
In addition to the LF2401A, TI also announced two other new DSP controllers aimed at more demanding, space-constrained applications. The TMS320LF2403A DSP controller provides 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 a 21 GPIOs, all packed into a 64-pin 10mm x 10mm TQFP package. The TMS320LC2402A DSP controller is pin compatible with the LF2403A and offers 6K words of ROM memory in place of Flash for cost reduction in high volume production. All of the new devices are based on TI's industry leading TMS320C2xLP™ DSP core, augmenting a broad and diverse family of TI DSPs that are well established in high-performance control markets.
TI customers who are designing applications with the LF2401A 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. For more information on the motor control foundation software, see www.ti.com/sc/dmcsoftware.
"With the LF2401A, TI went beyond traditional packaging to satisfy our customers' request for a smaller footprint device," said Scott Roller, TMS320C2000 worldwide marketing manager, TI. "In addition, the software libraries and support we offer make it easy for control designers to migrate to this platform, where they can take advantage of higher DSP performance and introduce programmable real-time control into their systems."
The industry's first 3.3V CAN transceiver
Removing the need for a 5V power supply to the control circuit, TI also announced today the industry's first 3.3V CAN transceiver (ISO 11898) to the market, optimizing the performance of the LF2403A DSP. Working off of the PCA82C250 industry standard footprint, the performance of the overall system is enhanced through reduced power, reduced component cost and board space and lower heat dissipation. The programmable slope control reduces Electro-Magnetic Interference (EMI), improving signal quality and reliability. Other important features of the SN65HVD230 CAN transceiver include signaling rate up to 1Mbps and low-current standby, resulting in low idle power consumption.
Availability, packaging and pricing
Sampling of TI's LF2403A DSP controllers is planned for the second quarter of 2001. ROM codes for the LC2402A are currently being accepted. The LF2401A will begin sampling in early third quarter 2001. The LF2401A will be packaged in a 32-pin LQFP, with pricing planned at $5.95 each in quantities of 100,000 units. The LC2402A will be packaged in a 64-pin TQFP, with pricing planned at $2.95 each in quantities of 10,000 to 100,000 units. The LF2403A will be packaged in a 64-pin TQFP, with pricing planned at $7.95 each in quantities of 100,000 units.
