ROHM and OKI Semiconductor have jointly developed a dedicated chipset supporting the Intel Atom processor E6xx Series formally known as Tunnel Creek. The new chipset combines a power management IC, clock generator IC as well as input/output hub IC. Rohm power management IC (PMIC) supplies all of the voltage rails that is required not only for the Intel Atom processor E6xx series and the Intel Platform Controller Hub EG20T, but also for the DDR2 memory and BIOS-storage SPI Flash connected to the Intel Chip. Additionally, it controls start-up and power down sequencing, eliminating any needs for an external microcontroller on a CPLD which is normally required in most conventional x86 processor designs. The Rohm Clock generator IC (CGIC) provides all of the clocks needed by the Intel chip and the controller hub, plus by commonly employed external devices such as SATA, USB, etc. On the other hand Oki Semiconductor has developed two types of application specific input/output hubs, the ML7223(V) and ML7213. The ML7223(V) is intended fro telecom terminal applications such as web enabled media phones, integrating a rich collection of industry standards I/O’s such as USBs, SATA, SD-Host, UART as well as application specific functions like IPsec hardware accelerator and echo and noise cancellers for hands-free operation. The ML7213, is mainly designed for in-vehicle infotainment applications.
