TMS320F28x kit

Texas Instruments Inc. has announced five new experimenter and application-specific development kits for its TMS320F28x digital signal controllers. Making it easier to jump-start 32bit based digital power and embedded control designs, with interchangeable processor card modules, or controlCARDs, Experimenter Kits with breadboard areas for full access to device signals, and application specific DC/DC and AC/DC Digital Power Developer's Kits. To reduce further development time, each kit includes code examples and full hardware design details along with TI's Code Composer Studio (CCStudio) 32Kbyte limited IDE. To accelerate development of software controlled digital power applications, the Digital Power Experimenter's Kit will be free to attendees of the one-day digital power workshops being held worldwide starting in June.

By adopting the new TMS320C2000TM controlCARDs, OEMs can rapidly build prototypes and even full production systems using the complete controller subsystem that comes on a small (90mm x 25mm) removable 100-pin DIMM form-factor card. Key analog, digital I/O signals and JTAG test pins are available through the controlCARD interface and only a 5V input is needed as all other power levels are provided on the board.

The first two controlCARDs are based on the TMS320F28335 floating-point DSC (running at 150MHz with 512Kbytes of flash memory) and the F2808 fixed-point DSC (at 100MHz and 128Kbytes of flash memory). The F28335 and F2808 controlCARD are $69 and $59, respectively.

Starting at $89, the C2000 Experimenter Kits include either the TMS320F2808 or floating point F28335 controlCARD and a docking station. Full access to all controlCARD pins is provided by the docking station, along with a 4-pin RS-232 interface, and a breadboard area for designers to add components.

Digital power
Digital control of power conversion systems results in lower overall cost through the consolidation of functions on to a programmable controller while enabling real time intelligent monitoring of load conditions, and improved system reliability and efficiency. Three new Digital Power Application Kits help bring these benefits to digital power management in communications infrastructure, industrial and consumer applications.

The Digital Power Experimenter's Kit is designed for those new to software based digital power management by providing a high function development environment including a DC/DC motherboard using two TI digital non-isolated PowerTrain modules along with an F2808 controlCARD. The DC/DC board also includes a digital multimeter and an active load that design engineers can use to perform transient response analysis and tuning. The Digital Power Experimenter's Kit comes with the 32Kbyte CCStudio IDE, a complete downloadable free software package that includes a working system and additional digital power instructional materials. The DC/DC Digital Power Developer's Kit targets multi-rail and multi-phase applications using a F28044 DSC based controlCARD to demonstrate the capabilities of the device as a 16-rail digital power controller. The DC/DC Developer's kit includes a DC/DC motherboard using eight TI digital non-isolated PowerTrain modules useful for prototyping DC POL power control in a wide range of equipments for industry, communications infrastructure and consumer electronics. The DC/DC Developer's kit includes the 32Kbyte CCStudio IDE, and a complete, free downloadable software package. The AC/DC Developer's Kit is a complete, 80W (max) rectifier development platform and uses a two-phase interleaved power factor correction (PFC) front end and a phase-shifted full-bridge secondary. The system is fully controlled by a single F2808 controlCARD and is useful for prototyping communications systems such as server farms and base stations, as well as telecom and consumer equipments. The AC/DC Developer's Kit includes the 32Kbyte CCStudio IDE and a complete, free downloadable software package.

Available immediately are the $59 F2808 based controlCARD, $89 C2000 Experimenter's Kit with F2808 controlCARD and $229 C2000 DC/DC Experimenter Kit with the F2808 controlCARD. The $325 DC/DC and $695 AC/DC Developer's Kits are available for order entry with shipping in July.

Along with the Experimenter's and Developer's Kits, designers will need an emulator for communication between the host PC and TI kits. The new $299 USB2000 JTAG emulator from Blackhawk is now available for purchase through TI and authorized distributors. All prices are suggested resale.
