Kawasaki Microelectronics Inc. and Kawasaki LSI Inc. introduce KL5KUSB201 LSI,
which is designed based on USB Specification revision 2.0 and operates as both
USB2.0 High Speed and Full Speed transceiver chip. It has two modes – UTMI
Specification compatible mode and Kawasaki Original mode. In Kawasaki Original
mode, th e LSI ha s sev eral con veni ent fun cti on s uch a s au tom ati c CRC gener ati on and
verification, transmit packet abortion and automatic test packet generation for High
Speed Signal Quality test. The LSI is recognized as USB2.0 PHY chip and customers
are able to build up USB2.0 compliant device system with their logic and PHY control /
endpoint buffer function (SIE), which is available by Kawasaki or other IP vendor.

1.1 Chip Functionality
KL5KUSB201 Fucntionality is summarized below.
1. HS Chirp Signal Generation and Detection
2. Support for both High Speed (480Mbit/sec) and Full Speed (12Mbit/sec)
3. For received packet, phase lock, buffering, SYNC detection, NRZI decode, bit
un-stuffing, CRC error detection (optional), serial to parallel conversion are
performed. 16bit data is drived on SIE bus
4.For packet transmission, parallel 16bit data is received, serialized, CRC
generation (optional), bit stuffed and NRZI encoded. Packet is transmitted onto
USB bus with SYNC and EOP attached
5. USB Bus status is delivered for outside SIE to monitor it
6. Function is controlled by Input Signals
7. Function defined by UTMI Specification is supported
8. Stand-alone Test packet generation for High Speed Signal Quality

2. Chip Architecture
Internal Architecture of KL5KUSB201 is shown in figure 2. The LSI consists of 6 major
blocks as follows. FrontEnd block transmits and receives USB signals. HS DLL block is used to re-clock High Speed signals with internal 480MHz clock. EBUF block
is for buffering High Speed signals. Shared Logic block includes such function as
NRZI decode, bit un-stuffing, CRC check, serial to parallel conversion for both High
Speed and Full Speed USB sig nals. SIE _IF blo ck in terf ac es wi th SI E bu s si gnal s. Fo r
Full Speed operation, DPLL block is used to re-clock the Full Speed signals with
internal 12 MHz clock instead of FrontEnd, HSDLL and EBUF blocks. For receiv ed
signals, the LSI locks them in HS DLL and is bufferi ng them in EBUF. Then signals
are transf erred to Shared Logi c to co nvert data format, check th e CRC, convert from
serial to parallel. The data is finally delivered to the SIE bus through SIE_IF. For
transmit operation, incoming parallel data is received in SIE_IF and sent to Shared Logic to perform parallel t o serial conversion , CRC generation, bi t stuffing and NRZI
encoding. Finally the data is transmitted onto the USB bus through FrontEnd block.
High Speed or Full Speed operation is selected by SIE control signals. USB bus status
