Sauer-Danfoss and Texas Instruments Inc. (TI) have announced the availability of eight Plus 1 hardware modules based on TMS320F2810 and F2812 digital signal controllers. The two companies said that these modules enable OEMs to reduce design time while increasing system features and functionality.

According to Sauer-Danfoss and TI, the F28x based modules let OEM designers tap into 150MIPS of TI's DSP technology to develop high performance control systems for machinery functions such as transmissions, hydraulics and operator interfaces with lower running costs and longer service life, while enjoying the peripheral integration and ease-of-use typically found in a microcontroller (MCU) based system.

"We needed a cost effective controller that could offer enough performance to implement complex control systems in software," shared Dan Ricklefs, Sauer-Danfoss product portfolio manager. "The F2810 and F2812 controllers provided us with 150MIPS to handle the most sophisticated algorithms while still oversampling analog inputs for increased precision at the same timesomething we could not have achieved with most of the MCUs we considered."

As part of the system of easy-to-use software tools, powerful programming environment, input/output (I/O) modules, graphical terminals and joysticks software and hardware modules, the PLUS 1 systems allow manufacturers of mobile equipment to design CAN-based electronic control systems that provide fast closed-loop, real-time performance with increased reliability. Using a PLUS 1 system, design engineers can select from a library of software control objects and modular control hardware to build a system scaled to their specific needs.

TI's DSP-based F2810 and 2812 controllers provide eight of these PLUS 1 modules with an integrated processing core to control the system's transmissions, drive-trains and valve controls. Functionality also extends to controlling equipment such as blades, grippers and buckets, as well as hydraulic and electronic control steering.

The TMS320C2000 digital signal controller

Based on TI's 32bit TMS320C28x DSP core, the F2810 and 2812 controllers integrate up to 128Kw of on-chip flash memory for simple reprogramming during development and in-field software updates. Optimized event managers include pulse-width modulation (PWM) generators, programmable general-purpose timers and glueless capture encoder interfaces. The device also features an on-chip, 12-bit ADC with capable throughput of 12.5MSPS and dual sample-hold, providing fast response for tight control loops.

In addition, all C28x DSPs are supported by a unique IQ math library. This combination allows designers to port floating-point algorithms to a fixed-point processor in a matter of minutes. Five different on-chip standard communication ports, including CAN, provide simple communication interfaces to hosts, test equipment, displays and other components or networks.
