TI Shipping Industry's First DSP with On-Chip Flash MemoryDSP Controllers Expand to Further Address Digital Motor Control Market
The volume production, flash-based TMS320F240 DSP is pin- and code-compatible with TI's 'C240 ROM-based DSP of the TMS320C24x generation, a product line dedicated to embedded control applications such as motor and motion control, appliances, industrial automation, power supplies, automotive, and heating, ventilation and air conditioning (HVAC) systems. TI Offers Highest Levels of Integration in DSPs Today TI also disclosed that it is sampling two other flash-based DSPs within its DSP controller roadmap. The TMS320F241 and TMS320F243 integrate both flash memory and the industry's only Control Area Networking (CAN) bus. This bus is emerging as the leading bus for industrial control. With the CAN interface, these two devices support complex industrial applications that require control of multiple motors and inter-system communication. The 'F243 also integrates an expansion bus for the use of additional memory. "TI has successfully combined DSP processing power, microcontroller peripheral integration and flash memory on to a single chip, enabling breakthrough system designs," said Christophe Chene, worldwide marketing manager for TI's Digital Control Systems Group. "The immediate availability of multiple flash devices and the economies of scale to drive aggressive ROM pricing over time uniquely positions TI as the leading DSP supplier in the embedded control arena." Based on TI's T320C2xLP DSP core executing 20 million instructions per second (MIPS), the 'C24x DSP controllers include a 10-bit analog-to-digital converter (ADC) with an 850-ns typical conversion time and a dedicated Event Manager that supports multiple pulse-width modulation (PWM) channels and dead-band logic. These functions and others allow designers to make use of the DSP's high performance to reduce or eliminate mechanical linkages and electronic components, achieving lighter-weight, quieter end products with lower overall system costs. Tools and Support Bring Faster Time-to-Market TI offers a full complement of system-level development tools, including an optimized DSP compiler, IEEE 1149.1 JTAG-based emulation tools and evaluation module (EVM) boards. TI also offers high-level programming options, as well as compact, ready-to-produce reference designs integrating DSP control and power electronics. In addition, a library of motor control algorithms, ranging from volt-ampere to Kalman filter sensorless control, is available for all motor types, including alternate current (AC) induction, brushless and switched reluctance machines. Spectrum Digital, Technosoft and White Mountain DSP are among TI's third parties who provide tools and software support for the 'C24x DSPs. Pricing, Packaging and Availability TI's TMS320F240 DSP is available in volume today from TI and its authorized distributors. Packaged in an 132-pin plastic quad flatpack (PQFP), it is priced at $15.51 each in 10K units. The TMS320F241 and TMS320F243 DSPs are sampling today and are available from TI and its authorized distributors. The 'F241 is packaged in a 68-pin plastic leaded chip carrier (PLCC) and a 64-pin PQFP and is priced at $12.73 each in 10K units. The 'F243 is packaged in an 144-pin thin quad flatpack (TQFP) and is priced at $14.39 each in 10K units.

HOUSTON (Aug. 24, 1998) -- Volume availability of the industry's first digital signal processor (DSP) with on-chip flash memory targeted at motor, motion and process control was announced today by Texas Instruments (TI), the world's leading DSP solutions provider. Motor manufacturers, like Mitsubishi Electric Corporation, plan to use the flash-based DSP to speed time-to-market. Motor designers can program quickly to flash memory and then transfer that code to a more cost-effective ROM-based DSP for volume production.
