Dialog Semiconductor, playing a key role supporting Intel’s Atom E6xx platform, announced a single-chip power management and clock driver companion IC—the DA6011—for the new processor series.
The DA6011 supplies power to the Atom CPU, IO hubs, memory and boot flash. It is intended to cut system BOM costs and shrink development time associated with atom platform applications as it integrates two formerly discrete solutions.
The device, demonstrated at Intel’s Developer Forum in San Francisco this week, manages start-up, state-transitioning and power down steps while providing full clock tree synthesis on Atom platforms.
Key features of the power supply capabilities (mouse over the diagram below for more detail):
2 DC/DC buck converters with external FETs
2 DC/DC buck converters with integrated FETs
2 buck converters (IMVP-6 specification)
11 high-performance LDOs using Dialog Smart Mirror technology
Key features of the clock synthesizer:
4 fractional division-featured PLLs
14.318 MHz crystal oscillator serves as reference clock for the PLLs
Supports I/O-hub clocks including PCIe (100MHz); SATA (100/75/50MHz); USB (48MHz) and more
The DA6011 integrates a hard-coded system-management controller that supports:
Intel Topcliff (EG2OT)
ST ConneXt STA2X11
OKI ML7213 IVI
OKI ML 7223 MP
The 6011 is a natural follow-on to the DA6001, an integrated power and clock supply IC for the Intel Atom Z5xx series. Michael Maurer, technical marketing manager for Dialog’s automotive and industrial business unit, said the design of the 6011 was an interesting challenge in terms of isolation.
“We learned a lot about how to build really quiet areas on silicon,” he said in an interview. “This technique was re-used on the 6011 where we are generating on the silicon quiet islands in the PLLs. There’s a strict partition-isolation between the PLLs and the parts where the buck regulators are switching.
“This means architecturally, you have on one side buck converters and on the opposite side in quiet areas, the PLLs. That’s the silicon side. For the isolation of the ball out, we use a strict double row of ground or permanent power pins separating clock signals from switching signals,” he added.
Maurer said employing the single-chip DA6011 could cut development time by roughly two weeks on a three-month development project, but that improved productivity really depends on the design team's experience level.
Dialog officials also noted that the DA6011 is being used in congatec’s Qseven embedded PC conga-QA6 for clocking and power management and is being demonstrated at IDF as well.
Availability: The DA6011, packaged in 11x11mm VFBGA packaging and manufactured in a quarter-micron TSMC process, is sampling; production volumes for automotive applications will be available in Q1 2011.
Pricing: $3.50-$4.50 per device, depending on volume.
