S1R72C05B08E100

Controllers Overview

The S1R72C05B08E100 is a USB host and device controller LSI supporting USB 2.0 high-speed mode with separate ports for host and device operation. It features an IDE interface suitable for mobile or car-mounted electronic devices with built-in HDDs. The chip supports HS (480 Mbps), FS (12 Mbps), and LS (1.5 Mbps) transfers, with built-in termination resistors eliminating external impedance adjustment components. It includes a 4.5 kB shared USB FIFO and a 64 B Media FIFO. Power supplies are 3.3 V (HVDD), 1.8 V (LVDD), and variable 3.3 V to 1.8 V (CVDD). The package type is PFBGA-121, and the guaranteed operating temperature range is -40 °C to 85°C.
