The IT8152G, an advanced RISC-to-PCI companion chip that supports SA1110 32-bit RISC microprocessor interface, is especially designed for the main applications in Datacomm, Telecomm, and Internet Appliances and Networking devices. This companion chip interfaces directly to RISC processors, and provides a bridge to link host bus and PCI bus. It also provides a Shared Memory (SDRAM) Controller, Low Pin Count (LPC) Host Controller, Interrupt Controller, DMA Controller, Timers, USB Host Controller, Digital AC'97 Controller, GPIO Controller and Power Management.

Paired with Intel's SA1110 RISC microprocessor interface, the IT8152G provides a low cost, high performance host to PCI bridge function for any system applications in Datacomm/Telecomm products.

The IT8152G is available in two packages: 208-pin PQFP and 208-pin LBGA.
