PORTLAND, Ore.--Greener appliances, industrial process controllers and data-center server farms are being made possible, according to Freescale Semiconductor, by its just announced MC56F82xx digital signal controller (DSC). The new greener-DSC combines a high-speed microcontroller core with digital signal processor (DSP) capabilities and pulse-width modulators with nanoscale precision.
Freescale designed the DSC for advanced motor control as well as for power-conversion applications in on-board digital power supplies used in telecommunications, industry and servers. Its 56900E core provides programmability with DSP capabilities and on-chip peripherals include pulse-width modulators with nanoscale placement accuracy, fast analog-to-digital converters (ADCs) and embedded flash memory for algorithms.
"Green applications can enhance the energy efficiency of their power conversion step using our new DSC, including solar inverters, white goods appliances, hybrid automotive batteries and LED lighting," said Raul Hernandez, Technical Marketing Manager for Freescale's Microcontroller Solution Group.
Nine on-chip pulse-wide modulation channels--six with nanoscale accuracy to enhance power conversion efficiency--complement two 3.3 million sample per second ADCs for reduced signal ripple. A crossbar switch allow on-chip module interconnection to be programmable.
Freescale's MC56F82xx family takes aim at digital power conversion applications such as board-mounted digital power supplies for servers, industrial and telecom power supplies and advanced motor control.
Support is provided by Freescale's CodeWarrior Development Studio, its Processor Expert software libraries and the Tower board-level prototyping system. FreeMASTER software also allows control of MC56F82xx applications remotely with a graphical user interface on a PC.
