Highly integrated power and Clock supply IC for the Intel® Atom™ processor Z5xx series

The DA6001 is a highly integrated system controller, designed to support the Intel® Atom™ Z5xx series platform for embedded computing applications, automotive applications like in-vehicle infotainment, netbooks and mobile internet devices. The DA6001 provides all power supplies, power management and clock supplies in a single chip, and has been optimized to deliver enhanced power efficiency to the platform.

Sourcing Dialog Semiconductor’s DA6001 with a single supply voltage the device provides, low noise supplies to all platform voltage domains and provides current to supply additional system DDR2 memory as well as the firmware hub memory.

The DA6001 integrates six high performance low dropout (LDO) voltage regulators using Dialog’s patented Smart Mirror™ technology, supplying platform power domains with the corresponding voltage and current. It includes a high efficiency DC-DC buck controller which is designed according to Intel® Atom™ processor IMVP-6 specification, providing the core voltage to the CPU via its external FETs. 3 additional high efficiency DC-DC buck converters will source the hardware engines of the Intel Atom platform, the front side bus (FSB) and the internal as well as the external system memory. The DA6001 also provides a push-pull source to terminate the address lines of the DDR2 system memory. It furthermore includes a charge pump, ensuring proper reference voltage generation, even if the input voltage drops below 5V.

A state machine that controls the complete system start-up and shut-down, operates autonomously in stand-by and active mode. This reduces the overall system power consumption even when going into stand-by or power down mode.

A standard 14.3MHz crystal oscillator generates the reference clock for the three implemented fractional division featured PLL’s, driving with push-pull amplifiers the platform according to Intel’s CK610 specification.

The DA6001 is designed for the automotive ambient temperature range of -40 .. +85°C. and will be qualified on the basis of AEC-Q100.
