GENERAL DESCRIPTION

The ML60851D is a general purpose Universal Serial Bus (USB) device controller. The ML60851D provides a

USB interface, control/status block, application interface, and FIFOs. The FIFO interface and two types of

transfer have been optimized for BulkOut devices such as printers and BulkIn devices such as digital still cameras

and image scanners. In addition, Mass Storage devices are also applicable to this device.

FEATURES

• USB 1.1 compliant

• Built-in USB transceiver circuit

• Full-speed (12 Mb/sec) support

• Supports printer device class, image device class, and Mass Storage device class

• Supports three types of transfer; control transfer, bulk transfer, and interrupt transfer

• Built-in FIFOs for control transfer

Two 8-byte FIFOs (one for receive FIFO and the other for transmit FIFO)

• Built-in FIFOs for bulk transfer (available for either receive FIFO or transmit FIFO)

One 64-byte FIFO

Two 64-byte FIFOs

• Built-in FIFO for interrupt transfer

One 8-byte FIFO

• Supports one control endpoint, two bulk endpoint addresses, and one interrupt endpoint address

• Two 64-byte FIFOs enable fast BulkOut transfer and BulkIn transfer

• Supports 8 bit/16 bit DMA transfer

• Supports protocol stall

• VCC is 3.0 V to 3.6 V

• Supporting dual power supply enables 5 V application interface

• Built-in 48 MHz oscillator circuit
