Freescale Expands DSC Portfolio for Digital Power and Motor Control
Freescale Semiconductor has expanded its family of digital signal controllers (DSCs) that are said to offer increased performance, and a flexible set of peripherals with reduced system costs for industrial applications. The MC56F82xx family is especially useful for digital power conversion applications such as board-mounted digital power supplies for servers, industrial and telecom power supplies and advanced motor control.
The advanced MC56F82xx family is a member of the 56800E core based family of DSCs. It combines the functionality of a microcontroller (MCU) and the processing power of a digital signal processor (DSP) with a wide set of peripherals including a high speed pulse width modulator with NanoEdge placement as well as two ultra-fast analog-to-digital converters (ADCs) to create an extremely cost-effective, powerful and versatile embedded control solution. According to the company, the MC56F82xx devices are among the fastest DSCs with embedded Flash in Freescale’s portfolio and one of the most cost-effective DSC offerings on the market.
"Developers are seeking technologies to enhance the cost effectiveness and energy efficiency of power conversion and motor control applications such as solar inverters, white goods appliances, hybrid automotive batteries and LED lighting," said Aiden Mitchell, Director of Industrial and Multi-market MCUs for Freescale. "The MC56F82xx family’s combination of price/performance, peripherals and energy efficiency allows designers to convert to digital control in order to set the pace for application innovation."
The MC56F82xx includes up to nine enhanced flex pulse width modulation (PWM) channels, including six with NanoEdge placement, helping to enhance power conversion, functionality and accuracy. The on-chip ADCs can achieve up to 3.33 million samples per second, helping to reduce signal ripple to precisely modulate energy. The devices include an inter-modular crossbar switch that allows programmable, internal module connections between and among the peripherals and package pins.
Up to four times more energy-efficient than other available DSC offerings, the MC56F82xx devices are designed to operate at 60 MHz and up to 3.6V. According to the company, the DSCs provide an array of cost-saving features that help eliminate the need for external components, reducing overall bill of material costs.
MC56F824x/5x family features include: 60 MHz operation frequency; 56800E digital signal processor engine with dual Harvard architecture allows as many as six operations per instruction cycle; up to 64KB of embedded on-chip Flash memory with EEPROM emulation capability simplifying system complexity and cost; eFlexPWM with up to nine channels, including six channels with high resolution NanoEdge placement to achieve precise switching frequency generation; two 8-channel, 12-bit analog-to-digital converters (ADCs) with dynamic x2 and x4 programmable amplifier to precisely measure power supply and motor control current; three analog comparators with integrated 5-bit DAC references; cyclic redundancy check generator; two 16-bit quad timers (2 x 4 16-bit timers); and an inter-module crossbar switch allowing programmable internal module connections between and among eFlexPMW, ADC, QuadTimers, DACs, HSCMPs and package pins.
MC56F824x/5x product samples are available now. Suggested resale pricing for the MC56F824x/5x family starts at $2.70 (USD) in 10,000-unit quantities.
