Recently, Texas Instruments (TI) announced that its TMS320F280xx digital signal controller family for motor control, digital power conversion and intelligent sensor control applications has added four low-cost members to help embedded control designers achieve the transition to 32-bit digital signal processor controllers. The new TMS320F28015 and F28016 controllers with 60MHz ultra-high performance have a minimum price of only $3.25 per 1,000-piece batch, while the new TMS320F2801-60 and F2802-60 controllers based on the current TMS320F2801 and F2802 devices also achieve 60MHz performance. TI will also launch a new digital power development kit, which includes the TMS320C2000 digital power (DPS) software library and the Tier Electronics hardware module series, which engineers can use to control existing platforms.
High-resolution PWM technology enables a wide range of product families and peripheral options.
Considering that many designers are upgrading their current designs based on 8- or 16-bit microcontrollers (MCUs), TI's 11 controllers in the F280xx family are software and pin-to-pin compatible. These devices not only have 32-bit DSP performance, but also implement peripheral integration similar to MCUs for ease of use. Therefore, all designs using F280x can implement 32-bit data processing; and the mixed 16/32-bit instruction set provides higher performance and code density. The on-chip integrated 12-bit analog-to-digital converter (ADC), quadrature encoder (QEP) interface, timer capture comparison function, and 10 independent pulse width modulation (PWM) output channels can facilitate the realization of complete system integration control functions. Depending on the specific product, communication interfaces include controller area network, I2C, UART and SPI ports.
All four new F280x devices use TI's latest 150 picosecond (ps) resolution pulse width modulator (PWM) technology that will be patented. High-resolution PWM (HRPWM) can achieve 16-bit accuracy in a 100KHz control loop, or 12-bit accuracy at 1.5MHz, which can provide higher output accuracy, power density, and smaller magnetic components for power developers, thus facilitating the realization of smaller and lower-heat power supplies. The above advantages are also crucial for applications such as AC/DC rectifiers that require high tolerance, faster transient response, and smaller ripple amplitude. For motor control applications such as home appliances and automobiles, designers can not only reduce overall system costs through integration and lower device costs, but also give full play to the performance advantages of 32-bit technology to achieve advanced control technologies such as position sensorless vector control of three-phase motors. Position sensorless vector control has high requirements for processors, which can meet the needs of developers for smaller size and lower cost of system motors and power electronics.
All four new controllers are packaged in 100-pin LQFP packages and meet AEC Q100 automotive standards. Developers can program these products through the TMS320F2808 eZdsp development kit (TMDSEZS2808). The eZdsp kit is available now through TI authorized distributors for $495 and includes a reference hardware platform with a PC USB interface and the TI Code Composer Studio integrated development environment.

New hardware- and software-based development kits simplify digital power control design
Initially targeted 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 software library provides reference software for key functions commonly used in applications such as AC/DC rectifiers, solar inverters and uninterruptible power supplies. Written in optimized C, this free, well-documented software helps engineers new to digital power control apply analog experience to the digital domain. DPS library components currently available include dual-phase boost power factor correction (PFC), multi-channel DC/DC conversion and single-phase DC/AC inverter, with more software components to be provided in the future. The
DPS hardware modules are low-cost circuit boards provided by Tier Electronics, a leading TI third-party partner. With the help of these modules, engineers can quickly and easily start digital power design work with F280x controllers without the time-consuming task of building their own controller or power stage hardware. The first two modules in this kit are mainly targeted at PFC and DC/DC converter designs.
The PFC module is a dual-phase boost topology, while the DC/DC module is a dual-phase shifted full-bridge topology. All boards are available directly from the Tier website for $295 each and can be easily connected to the TI TMS320F2808 eZdsp development kit, which provides the controller hardware. The eZdsp can control each DPS hardware module individually or connect the modules together for AC/DC rectifier applications. TI is now offering the TMS320F2808 eZdsp development kit (TMDSEZS2808) for $495. Tier will begin offering the DPS hardware module later in September.

It's a new technology that just came out. The cheapest one is 295 dollars. I really can't afford it.
