The Lattice I3C IP Core is designed to comply with the MIPI I3C specification. Both Controller and Target versions of this IP Core are available.

The I3C Controller accepts commands from a LMMI interface or APB/AHB-Lite if user selected the optional standard interface. These commands are translated into I3C signals and forwarded to I3C target Device. The I3C Controller can operate in interrupt or polling mode. This means that the user can choose to poll the I3C Controller for a change in status at periodic intervals or wait to be interrupted by the I3C Controller when data needs to be read or written.

Eases Sensor System Design Architectures - The MIPI I3C interface eases sensor system design architectures in mobile wireless products by providing a fast, low-cost, low-power, two-wire digital interface for sensors. I3C a single scalable, cost effective, power efficient protocol to solve issues with the high protocol overhead, power consumption, nonstandard protocol, separate lines for interrupt and the rest requirement.

Offers Greater Than 10x Speed Improvements - I3C offers greater than 10x speed improvements, more efficient bus power management, new communication Modes, and new Device roles, including an ability to change Device Roles over time.

Supports Several Communication Formats - I3C Controller IP supports several communication formats, all sharing a two-wire interface: SDA bidirectional data pin, and SCL bidirectional for the Controllers.

Features

  • Compatible with MIPI I3C Specification v1.1.1
  • Two wire serial interface up to 12.5 MHz using Push-Pull
  • Legacy I2C device coexist on the same bus (with some limitations)
  • Dynamic Addressing while supporting Static Addressing for legacy I2C devices
  • I2C-like SDR messaging

1. Fmax is generated when the FPGA design only contains the SDR module, and the target frequency is 200 MHz. These values may be reduced when user logic is added to the FPGA design.
2. The distributed RAM utilization is accounted for in the total LUT4s utilization. The actual LUT4 utilization is distribution among logic, distributed RAM, and ripple logic.
