High-end control applications require high performance, floating-point precision and optimized control peripherals to meet stringent system efficiency, accuracy and reliability requirements. Addressing this need, Texas Instruments Incorporated (TI) (NYSE: TXN) announced the TMS320C2834x Delfino controllers that double floating-point performance over existing TMS320C2000[tm] devices and include 516KB of single cycle access RAM memory, high resolution pulse width modulation outputs (PWMs) as well as other control-oriented features. The new Delfino devices are supported by two new modular controlCARD tools designed to jump start development of real-time control applications such as servo drives, renewable energy, power line monitoring and driver assistance.
Key features and benefits of C2834x Delfino controllers
- 300 MHz C28x core for fast interrupt response, minimal latency, execution of complex control algorithms and real-time data analysis
- 32-bit floating-point unit eases programming of magnitude calculations, eliminates scaling and saturation burden and improves performance of algorithms such as Park transforms and proportional integral derivatives (PID)
- 516 KB on-chip single cycle access RAM enables high-speed program execution and data access
- Flexible 65ps high-resolution PWM modules allow for optimal precision
- CAN, I2C, SPI and standard serial interface (SCI) peripherals provide easy connectivity for management of system communication
- External ADC interface gives developers flexibility to select from TI’s broad portfolio of high-accuracy analog-to-digital converters
- Code compatibility across the C2000 platform enables developers to easily scale product lines and reuse code in controllers ranging from 40 MHz PiccoloTM to 300 MHz Delfino
The C28343 and C28346 are the first devices in the C2834x series and are supported by the DIM100 controlCARD and DIM168 controlCARD. The controlCARDs are modular daughtercards designed to plug into TI’s portfolio of evaluation and application boards such as the recently announced Renewable Energy Developer’s Kit, Resonant DC/DC Developer’s Kit and Peripheral Explorer Developer’s Kit.
TI provides complementary analog signal chain and power management technology that helps enhance the system performance of applications based on Delfino floating-point controllers. TI’s analog-to-digital converters (ADCs) provide resolution, speed and an interface that offers data rates from 8-bits at 100 mega samples per second (MSPS) to 32-bits at 100 SPS. In addition, TI’s full range of high-efficiency power management solutions allows developers to more easily optimize their system power requirements.
