GENERAL DESCRIPTION

The ML60852A is a general purpose Universal Serial Bus (USB) device controller.

The ML60852A 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 ML60852A supports four types of data transfer such as control transfer, bulk transfer, interrupt transfer and isochronous transfer, and also supports five or six endpoints.

FEATURES

• USB1.1 compliant

• Supports full-speed (12 Mbps).

• Supports four types of transfer; control transfer, bulk transfer, interrupt transfer, and isochronous transfer.

• Endpoints: 5 to 6 endpoints

   Control EP 1

   Bulk/interrupt EP 3

   Isochronous/bulk/interrupt EP 1 or 2

• Built-in FIFO for data storage

• A two-layer configuration of FIFO for each of EP1, EP2, EP4, and EP5

• 8/16 bit DMA supported (EP1, EP2, EP4, and EP5)
