Product Summary

The L60852A is a general purpose Universal Serial Bus (USB) device controller. The L60852A provides a USB serial interface engine, USB transceiver, FIFOs, control/status registers, application interface circuit, and oscillation circuit thereby easily realizing a USB system. The L60852A supports four types of data transfer such as control transfer, bulk transfer, interrupt transfer and isochronous transfer, and also supports five or six endpoints.
