Description
Link
Protocol Engine (UDC-20) is a fully synthesizable soft core that
supports high-speed (480 Mbps), full-speed (12Mbps) signaling
bit rates.
Protocol engine reduces CPU burden by processing basic USB
2.0 protocols in hardware.
Endpoint numbers, configurations, and its FIFO densities
are flexible. Following is one of the configuration examples.
1) End Point 0
2) End Point 0
3) End Point 1
4) End Point 2
5) End Point 3

Overview
Fujitsu USB 2.0 device controller is a synthesizable core suitable
for different process. Corresponding physical interface in 0.18um
and 0.11um technology (supporting high and full speed operation)
also available for integration.
Generic CPU interface makes it easy to be integrated into overall
ASIC. Different endpoints are available for application such as
printer, scanner, digital still camera, bluetooth devices, digital set
top box,cable modems and PC Access Point to high speed wireless
connectivity.
Integrated SIE performs synchronization pattern recognition, bit
stuffing/ stripping, CRC check/ generation, serial/ parallel conversion,
PID verification, address recognition and handshake evaluation/
response.
The macro decodes and handles standard USB commands. Device
class specific command is passed on to the ASIC for further
processing.
PHY
PHY block consists of a 0.18um hard macro and a soft macro
(Receiving Block).
PHY block supports high-speed (480Mbps) and full-speed (12Mbps).
Contains high-speed Analog Blocks and high-speed SERDES
(serializer and de-serializer Logic) and provides a parallel interface
to UDC-20 protocol Engine.
