Reference board for optimising power of i.MX6 dual and quad processors
August 13, 2012 // Nick Flaherty
Dialog Semiconductor and NovTech have co-developed a reference design for its single-chip system power management IC (PMIC) to optimise the power requirements of all 35 voltage rails used with Freescale's multicore i.MX 6 series applications processors.
The NOVPEK i.MX6Q/D i.MX 6 Platform Evaluation Kit enables OEMs to more rapidly bring to market precision-controlled, high-end systems based on i.MX 6 series processors.
By using Dialog's configurable PMIC, the reference board delivers multiple settings for each peripheral voltage rail, programmable control for multiple power-on events and an accurate power consumption analysis framework to cut the power consumption of any i.MX 6 series application.
The Dialog device powers the i.MX 6 series system-on-chip and system peripherals - including external memories, WLAN, Bluetooth, GPS, FM receivers and modems - on a very small (< 200mm2) active PCB area with just a 1mm external component height, including all inductors, enabling the creation of thinner mobile products with longer battery life.
For greater performance and enhanced multimedia capability, the Dialog PMIC delivers over 14A total power capability to the Freescale i.MX 6 series system including CPU, memories and other peripherals on the reference board. It supports multiple voltage settings for each of the 35 peripheral voltage rails on the devices to provide an accurate power consumption analysis framework. In addition, the chip provides flexibility and configurability to precisely control the start-up sequences, output voltages and DVC ramps.
With the PMIC's wide supply range of 2.7 to 5.5V, the reference board is able to use a single cell lithium battery as well as 5V power supply.

The development platform for i.MX 6Quad from element14 (built to the Freescale SABRE Lite design) is an evaluation platform featuring the powerful i.MX 6Q, a multimedia application processor with Quad ARM Cortex-A9 cores at 1.2 GHz from Freescale Semiconductor.
This month, Freescale and element14 are giving away five such platforms, worth £128.06 each, for EETimes Europe's readers to win. The platform helps evaluate the rich set of peripherals and includes a 10/100/Gb Ethernet port, SATA-II, HDMI v1.4, LVDS, parallel RGB interface, touch screen interface, analog headphone/microphone, micro TF and SD card interface, USB, serial port, JTAG, camera interface, and input keys for Android.
