Introduction CH365 is a general interface chip based on PCI bus, supports I/O port mapping, expansion ROM and interrupt.

CH365 converts the 32-bit high-speed PCI bus into an easy-to-use 8-bit active parallel interface which is similar to ISA bus, for making low-cost computer board card based on PCI bus, and upgrading the original board card based on ISA bus onto PCI bus.

Compared with other mainstream buses,

CH365 Features

* l Realizes the slave device interface based on 32-bit PCI bus. l Converts into active parallel interface: 8-bit data, 16-bit address, I/O read and write, memory read and write. l Can set device identification (Vendor ID, Device ID, Class Code, etc.) of PCI board. l Supports write and read I/O port o
