ISH I3C Controllers

The ISH supports one I3C controllers, two-Wire I3C serial interface which consists of a Serial Data Line (SDA) and a Serial Clock (SCL).

The following are the ISH's I3C host controller specifications:

  • Modes Supported
    • I3C Controller (Single Controller) - other modes are not supported

  • In-band-interrupt (IBI) buffer depth of 16 bytes for command and status

  • Supports Data transfer to legacy I2C devices

  • Clock stalling support in Controller Mode

  • Supports various Data rates, such as, FM, FM+, SDR, HDR/DDR Rate

  • CRC/Parity Generation and Validation

  • Support for broadcast and directed CCC transfers

  • Detects arbitration loss due to incoming IBI and subsequently re-transmits the command.

  • Use of Duty Cycle to achieve Lower Effective Speed for SDR transfers to work with slower I3C
