Purpose-built exclusively as a dedicated I3C Primary Controller, this subsystem completely eliminates the massive silicon overhead and routing complexity associated with generic multi-mode or target-capable IP blocks. The result is an ultra-lean, area-optimized core that drastically minimizes gate count and static power leakage while delivering robust SDR data transfers of up to 12.5 Mbps.<\/p><p data-path-to-node=\"4\">The architecture features comprehensive In-Band Interrupt (IBI) support, advanced asynchronous timing controls, and an integrated master descriptor ring architecture for high-performance DMA operations. It provides backward compatibility with legacy Fast-mode (Fm) and Fast-mode Plus (Fm+) I2C devices, and and is designed to support the JEDEC JESD403-1 specification.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-2a66512 e-flex e-con-boxed e-con e-parent\" data-id=\"2a66512\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t<div class=\"elementor-element elementor-element-572e85f e-con-full e-flex e-con e-child\" data-id=\"572e85f\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-8bd84a8 elementor-widget elementor-widget-heading\" data-id=\"8bd84a8\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Core Features<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-d1b5e0c elementor-widget elementor-widget-text-editor\" data-id=\"d1b5e0c\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<ul data-path-to-node=\"7\"><li><p data-path-to-node=\"7,0,0\"><b data-path-to-node=\"7,0,0\" data-index-in-node=\"0\">Area-Optimized Host Architecture:<\/b> Pure Primary Controller design that strips away unused secondary controller and target logic to minimize silicon area, optimize routing, and reduce static power leakage.<\/p><\/li><li><p data-path-to-node=\"7,1,0\"><b data-path-to-node=\"7,1,0\" data-index-in-node=\"0\">High-Efficiency Data Rates:<\/b> Full SDR mode support driving data transfers up to 12.5 Mbps.<\/p><\/li><li><p data-path-to-node=\"7,2,0\"><b data-path-to-node=\"7,2,0\" data-index-in-node=\"0\">Automated Bus Provisioning:<\/b> Built-in hardware acceleration for Dynamic Address Assignment (DAA) and Common Command Code (CCC) execution.<\/p><\/li><li><p data-path-to-node=\"7,3,0\"><b data-path-to-node=\"7,3,0\" data-index-in-node=\"0\">Advanced Target Handling:<\/b> Seamless integration of In-Band Interrupts (IBI) and Hot Join support for dynamic peripheral insertion.<\/p><\/li><li><p data-path-to-node=\"7,4,0\"><b data-path-to-node=\"7,4,0\" data-index-in-node=\"0\">Native AMBA Bus Interfaces:<\/b> High-bandwidth system integration via an on-chip 32-bit AMBA AXI4-Lite Slave interface for host register access and a 32-bit AXI4 Master interface for dedicated DMA operations.<\/p><\/li><li><p data-path-to-node=\"7,5,0\"><b data-path-to-node=\"7,5,0\" data-index-in-node=\"0\">DDR5 Sideband Channel Ready:<\/b> Designed to support the JEDEC JESD403-1 specification for next-generation computing platforms.<\/p><\/li><li><p data-path-to-node=\"7,6,0\"><b data-path-to-node=\"7,6,0\" data-index-in-node=\"0\">Legacy Interoperability:<\/b> Backward compatible with standard Fast-mode (Fm) and Fast-mode Plus (Fm+) I2C target devices.<\/p><\/li><li><p data-path-to-node=\"7,7,0\"><b data-path-to-node=\"7,7,0\" data-index-in-node=\"0\">Robust Fault Tolerance:<\/b> Hardware-level error detection and autonomous bus recovery protocols, complemented by an integrated Digital Noise Filter (DNF) on SCL and SDA inputs.<\/p><\/li><li><p data-path-to-node=\"7,8,0\"><b data-path-to-node=\"7,8,0\" data-index-in-node=\"0\">Flexible Transaction Blocks:<\/b> Handles up to 255 continuous write or read bytes within a single command, alongside a low-power hardware Wake Up function.<\/p><\/li><\/ul><ul><li>Configurable Features<br \/>\u00a0 \u00a0 \u00a0\u2013 TX and RX FIFO (Depth of up to 512 locations)<br \/>\u00a0 \u00a0 \u00a0\u2013 Command Queue Depth<br \/>\u00a0 \u00a0 \u00a0\u2013 Response Queue Depth<br \/>\u00a0 \u00a0 \u00a0\u2013 DMA Rings (Up to 8 Command\/Response descriptor rings)<br \/>\u00a0 \u00a0 \u00a0\u2013 Frequency Divider for SCL via Configuration registers<\/li><\/ul><p>Status: In development (RTL and verification).
