Dialog's system power management IC for the Intel Atom processor cuts power
consumption and board space

Cuts cost, replaces discrete power management and external clock sources 

Dialog Semiconductor plc (FWB: DLG), has launched the first in a new family
of power management ICs (PMICs) designed to optimise the power efficiency
of applications using the Intel(R) Atom(TM) processor Z5xx series which is
being broadly adopted today. The DA6001 provides all power supplies, power
management and clock supplies in a single chip.

The PMIC improves battery life, simplifies design, improves system
reliability, requires less than half the board space and cuts the
bill-of-materials compared with using discrete power management parts.

The DA6001 supports the Intel Atom processor for embedded computing
applications, automotive applications like In-vehicle infotainment,
netbooks and mobile Internet devices. The device family will expand to
support future Intel Atom processors and platforms for the embedded and
portable space.

'The Intel Atom processor is power-optimized, delivering robust
performance-per-watt for cost-effective embedded applications. The DA6001
as a companion IC, adds the ability to minimise power consumption across
the complete platform, not just the processor, without adding the cost and
complexity of multiple power management and clocking devices to achieve
this,' said Juergen Friedel, vice president and general manager at Dialog.

'Embedded developers are designing products used in thermally constrained
environments and require very low-power solutions,' said Ton Steenman, vice
president, Digital Enterprise Group and general manager of the Low-Power
Embedded Products Division.  'The combination of the Intel Atom processor
Z5xx series and the DA6001 provides our customers with more choice in the
way they can deliver extremely power-efficient solutions to a variety of
embedded market segments.'

From a single supply voltage, the DA6001 provides low noise supplies to all
platform voltage domains and current for system DDR2 memory. Four DC/DC
buck converters power the platform hardware engine, the SCH core and FSB,
both internal and external system memory and the CPU core - meeting IMVP-6
specification for the Intel Atom processor.

Further platform power demands are supplied by 6 high performance, low
dropout (LDO) voltage regulators, using Dialog's patented Smart Mirror(TM)
technology, removing the need for a low power mode and simplifying power
control in the system. A dedicated push-pull LDO is integrated into the
device to terminate the address lines of the external RAM, further
minimising external components.

The DA6001 includes a clock synthesiser/driver according to Intel's CK610
specification providing all the necessary clocks via 3 separate fractional
divisions PLLs.

Two analogue signal inputs can be multiplexed to a 10-bit ADC converter for
signal measurements and a charge pump, which is integrated to generate the
5V reference domain even if the input voltage drops below 5V. An autonomous
state machine manages the complete system start-up and shutdown procedures
as well as the state transitions of the Intel Atom processor during all
operational modes.

Engineering samples will be available from June 2009 with volume production
and AEC-Q100 qualified volume parts, for automotive applications, in the
second half of 2009.
