This half-length card supports the full I2C communications protocol and plugs into any available I/O slot in your PC. Based around the Philips PCF8584 I2C Bus Controller it will work with any IBM compatible ISA/EISA bus computer. PC I/O base address is selectable in the range 310 to 31E (hexadecimal). The adapter occupies this base address and the next address up. Bus termination, protection and hardware interrupt line (usage is optional) are all link selectable while I2C configuration and all other functions are software controllable.

All I2C features are available under software control including data transmission mode (master/slave, transmitter/receiver), own slave address and SCL clock speed when operating as a master (1.5/11/45/90KHz). Both polled and interrupt driven modes can be supported, making programming in popular languages easy. A "transparent" real-time bus monitor program is also provided. The ICA90 fully supports multi-master operation and associated bus arbitration.
