Original Press Release:
TI Expands Portfolio with Industry's Lowest Cost 32-bit Digital Signal Controller Starting at $3.25
New TMS320F280x Controller-Based Digital Power Development Kit Accelerates Design
HOUSTON, June 27 // -- Helping embedded control designers make the transition to 32-bit digital signal processor- (DSP) based controllers, Texas Instruments Incorporated (NYSE:TXN) (TI) has added four new low cost members to the TMS320F280xx digital signal controller series targeted at motor control, digital power conversion and intelligent sensor control applications. The new TMS320F28015 and F28016 controllers offer 60MHz of performance starting as low as $3.25 (in 1Ku quantities) while the new TMS320F2801-60 and F2802-60 controllers also offer 60 MHz of performance and are based on the current TMS320F2801 and F2802 devices. TI is also announcing a new digital power development kit, which consists of a TMS320C2000(TM) Digital Power Supply (DPS) software library and a series of hardware modules from Tier Electronics that provide off-the-shelf platforms that engineers can control with this software library. For more information on the new 60 MHz controllers and the Digital Power Development Kit, see www.ti.com/lowcost280xx .
Broad Portfolio and Peripheral Options with Patent Pending High Resolution PWM
As designers consider upgrading existing 8- or 16-bit microcontroller- (MCU) based designs, TI's F280xx controllers offer a portfolio of eleven software and pin-for-pin compatible devices with 32-bit DSP performance combined with the peripheral integration and ease-of-use of an MCU. All F280x- based devices feature a 32-bit wide data path for superior performance and mixed 16/32-bit instruction set for improved code density. These controllers offer exceptional system integration by providing complete control system capabilities from signal input through the on-chip,12-bit analog to digital converter (ADC), quadrature encoder pulse (QEP) interfaces, and timer captures and compares through signal output with up to 10 independent pulse width modulation (PWM) channels. Depending on the device, communication interfaces include CAN, I2C, UART and SPI ports.
All four new F280x devices feature a patent-pending pulse width modulator (PWM) with 150 picosecond (ps) resolution. The high resolution PWM (HRPWM) provides 16 bits of accuracy in a 100 KHz control loop and 12 bits at 1.5 MHz. As a result, power developers benefit from designs with cleaner power output, higher power density, smaller magnetics and more compact, cooler supplies. These benefits are critical in applications like AC/DC rectifiers that require high tolerances and faster transient response with small ripple amplitude. For motor control applications such as white goods and automotive, designers can reduce overall system costs through integration and low device cost while leveraging the 32-bit performance necessary to implement advanced control techniques like sensorless vector control of three-phase motors. Using processor-intensive sensorless vector control can help developers to reduce the size and cost of a system's motors and power electronics required to meet their needs.

All four new controllers are AEC Q100 automotive qualified in 100-pin LQFP packaging. Developers can use the TMS320F2808 eZdsp Development Kit (TMDSEZS2808) to program all four of the new controllers. It is available today for $495 from TI authorized distributors. The eZdsp Kit includes a reference hardware platform with USB connection to the PC and the TI Code Composer Studio(TM) Integrated Development Environment.
New Software and Hardware Based Development Kit Eases Digital Power Control Design
Targeted initially at AC/DC rectifier and DC/AC inverter applications, the new digital power development kit includes the DPS software library and DPS hardware modules. The DPS library provides reference software for key functions used in an AC/DC rectifier, solar energy inverter, and uninterruptible power supply applications. This free, fully documented software, written in optimized C, will aid engineers new to digital control of power supplies and allow them to translate their analog experience into the digital realm. DPS library components available today include two-phase boost power factor correction (PFC), multi-channel DC/DC conversion, and a single- phase DC/AC inverter with additional software components to be added. The DPS library can be downloaded for free from www.ti.com/dpslib .
The DPS hardware modules are low-cost boards from Tier Electronics, a leading TI third party. The modules provide an easy way for engineers to start working on F280x controller-based digital power designs quickly without having to build their own controller or power stage hardware. The first two modules in the kit are targeted at PFC and DC/DC converter designs. The PFC module is a two-phase boost topology while the DC/DC module is a dual phase-shifted full-bridge topology. Each board is available individually for $295 directly from Tier at www.tierelectronics.com/ and connects easily to TI's TMS320F2808 eZdsp development kit, which provides the controller hardware. The DPS hardware modules can be controlled individually by the eZdsp or connected together for an AC/DC rectifier application. The TMS320F2808 eZdsp development kit (TMDSEZS2808) is available for $495 from Texas Instruments. The DPS hardware modules will be available from Tier starting in late September.
