DESCRIPTION
The M66290A is a general purpose USB (Univ ersal Serial Bus) device controller compatible with the USB specification version 1.1 and corresponds to full speed transfer. Built-in transceiver circuits meet all transfer type which is def ined in USB.
M66290A has FIFO of 3k Bytes for data transfer and can set 6 endpoints (maximum).
Each endpoint can be set programmable of its transfer condition, so can correspond to each dev ice class transfer system of USB.
