Hitachi provides PHY interfaces to realize high-performance LSIs.
With increasingly high LSI performance, the input/output interfaces of LSI circuits and reliability become crucial factors. On the basis of technology gained through the development for IT network equipment, we support PCI Express (with their high general-purpose applicability) and DDR3 SDRAM interfaces.

Hitachi provides high-speed interfaces to realize high-performance LSIs.
With increasingly high LSI performance, the input/output interfaces of LSI circuits and reliability become crucial factors. On the basis of technology gained through the development of IT network equipment, we provide serdes (serializer-deserializer) macro cells that support various interface standards, along with various kinds of I/O and high-precision PLLs.

Hitachi realizes high-performance LSIs by providing memory IP cores with high-speed and low-power consumption.
With increasingly high LSI performance, the need for memory IP cores with high-speed and low power consumption has become more pressing. We meet a broad range of needs by optimizing device selection through power-supply options and read-timing options for the sake of higher speeds in terms of cycles and access operation, including circuit technology for higher speeds and lower power consumption.
