Texas Instruments has announced the TMS320C2834x series of Delfino floating-point controllers designed to meet the stringent system efficiency, accuracy and reliability requirements of high-end real-time control applications. The controllers feature 300-MHz performance and include 516KB of single-cycle access RAM memory, high-resolution PWM outputs and 32-bit QEP modules as well as other control-oriented features.
Supported by two new modular controlCARD tools, the new Delfino devices feature a 300-MHz C28x core for fast interrupt response, minimal latency, execution of complex control algorithms and real-time data analysis. 32-bit floating-point precision eases programming of magnitude calculations, eliminates scaling and saturation burden and improves performance of algorithms such as Park transforms and PIDs.
The 516 KB of on-chip single-cycle access RAM enables high-speed program execution and data access, while 65-ps high-resolution PWM modules allow for optimal precision. Other features include CAN, I2C, SPI and standard serial interface (SCI) peripherals, an external ADC interface and code compatibility across the C2000 platform (from the 40-MHz Piccolo to the 300-MHz Delfino).
The Delfino microcontrollers are sampling now and priced at $8.95 in volume. Sample orders can be placed for the first two configurations available: the TMX320C28346, starting at $19.70 (100-unit pricing), is the superset configuration operating at 300 MHz and includes 516 KB of on-chip RAM, while the TMX320C28343 operates at 200 MHz, includes 260 KB of on-chip RAM and starts at $13.50 (100-unit pricing).
The C28346 DIM168 Experimenter's Kit (TMDXDOCK28346-168) and C28343 DIM100 Experimenter's Kit (TMDXDOCK28343) are also immediately available for order and are priced at $189 and $159, respectively.
