88-pin microcontroller


Sauer-Danfoss has announced the addition of a larger, general purpose microcontroller (the MC088-015-00000) to the PLUS+1TM product family. This new 88-pin microcontroller, which includes 42 inputs, 32 outputs and two CAN 2.0B ports, is an excellent choice for mobile machinery designs requiring a large number of input/output (I/O) connections in a concentrated space. “The new microcontroller extends the capabilities of the PLUS+1 family of mobile machinery control products introduced by the company in 2004,” said Dan Ricklefs, Product Portfolio Manager, Sauer-Danfoss, Ames, USA. “Whether OEMs are designing small machines with short CAN-bus communication lines or have a very large clustering of input/output needs, the new 88-pin device provides maximum design flexibility with the potential to reduce overall installed costs.” Extended Compatibility, Higher Power Capability, Efficient Control The new 88-pin microcontroller offers significantly expanded input/output capabilities, joining the 12-pin I/O module and 24- and 50-pin microcontrollers in the PLUS+1 family. The new device is equally suited for use as a member of a distributed machine control system or as a stand-alone microcontroller. The microcontroller was designed with three new features that significantly augment system compatibility, power and control. These features include: 1) four inputs that can be configured to read signals in the 4 to 20 mA range, such as from pressure and temperature sensors, 2) six 6-amp digital outputs to directly control higher power devices, such as starter solenoids and incandescent lamps and 3) 4 MB of on-board flash memory for logging everything from operational data to machine status. Overall, these features provide the designer with more options for differentiating vehicle design. PLUS+1 Product Family Features Consistent with other PLUS+1 products, the new 88-pin microcontroller includes a 5 Vdc regulated power supply for sensor circuits, two programmable LEDs to aid in diagnostics, environmentally robust Deutsch® connectors and a flexible 9 to 36 Vdc power supply. It also has flexible circuit designs and powerful Digital Signal Processor (DSP)-based control, typical of the PLUS+1 family. These features assure state-of-the-art control performance. As with the entire PLUS+1 line of microcontrollers and input/output devices, the new microcontroller is supported by the GUIDE application programming environment. With this tool set, OEMs can draw from the extensive library of Sauer-Danfoss software modules and graphically build an application to meet their individual needs. “OEMs can put the new microcontroller to work in a variety of mobile machinery ranging from agriculture to road building and construction equipment,” said Ricklefs. “Consistent with other PLUS+1 family products, the new 88-pin microcontroller is designed to withstand the harsh off-road environment. Microcontroller technology is a critical element in helping OEMs to meet future machine productivity and efficiency needs. The PLUS+1 suite of products helps bring these features to market in a very time-effective manner.”
