GENERAL DESCRIPTION
The ML60851A is a general purpose Universal Serial Bus (USB) device controller. The ML60851A
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 1.0 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
• V
CC
is 3.0 V to 3.6 V
• Supporting dual power supply enables 5 V application interface
• Built-in 48 MHz oscillator circuit
• Package options:
