I3C-SC: MIPI I3C Basic Secondary Controller
关于此报价
The I3C-SC core implements a versatile MIPI® Improved Inter Integrated Circuit (I3C) Secondary Controller core compliant with the latest MIPI I3C Basic specification. As a secondary controller, the I3C-SC can act either as a bus target or a bus controller. Compliant to the I3C Basic specification, the core communicates in Single Data Rate (SDR) mode but can tolerate High Data Rate (HDR) traffic. It can coexist and communicate with legacy I2C devices, and it can optionally be configured to operate as such in an I3C or I2C bus. When acting as a target, the I3C-SC needs no firmware support to parse and execute the broadcast or direct Common Command Codes (CCCs) relevant to I3C Basic targets. It can be assigned a Dynamic Address by the bus controller or use its legacy I2C static address, it supports Hot-Join and can generate In-Band Interrupts when directed by the host to do so. When the I3C-SC core is the only bus controller, then Hot-Join is not possible, and static addressing should be used. Designed for easy integration, the I3C-SC can operate in two different modes. Under normal mode, data from private I3C or legacy I2C write transfers are stored to a FIFO and made available to the host via an APB Subordinate interface. In a similar way, the host provides data to be used for private I3C or legacy I2C read transfers via the core’s APB subordinate interface. Alternatively, the core can operate in I3C-to-AHB bridging mode, where it autonomously converts private I3C or legacy I2C transfers to accesses on its AHB manager port using a simple yet configurable over-I3C protocol. Under the I3C-to-AHB bridging mode, the core acts as an I3C bus target, needs no software assistance, and provides the I3C bus controller access to the local AHB bus, enabling remote monitoring, configuration, debug, or data exchange. The selection between normal and bridging operation modes is under software control via the core’s control register.
