USB2.0 to 100 Ethernet Controller

PLL Clock Generator

A 12 MHz external crystal may be used with the KL5KUSB220 controller. Two pins, X1

and CLK, are provided to connect a lower cost crystal circuit to the device. There are two

PLL's in the KL5KUSB220, one PLL is configured as a x4 multiplier and the second is

configured as a x5 multiplier. The first PLL is used to generate the processor clock. The

processor has the ability to select the desired processor clock to 48 MHz (default) or

lower. The second PLL is used to generate the clock for the USB 2.0 SIE. Circuitry is

provided to generate the internal 48MHz clock requirements of the device. If a n exteran

12 MHz clock is available in the application, it may be used in lieu of the crystal circuit vy

connecting directly to the CLK input pin.

Unified Scatter Gather DMA Controller

The unified scatter gather DMA controller enables the high speed data through required

for USB 2.0 to 100Mb Ethernet. The processor creates the DMA Control Blocks (DCB's)

and enables reception or transmission on a channel. The unified DMA controller then

receives/transmits the data to/from the corresponding buffer specified in the DCB.

USB 2.0 Interface

The KL5KUSB220 Controller has USB 2.0 SIE (Serial Interface Engine) allowing both HS

(High Speed) and FS (Full Speed) operation. The controller has an interface to an

external UTMI Transceiver.

10Mb, 100Mb/sec Ethernet Interface

The KL5KUSB220 Controller has a built in the Ethernet MAC (Media Access Controller)

which is fully compliant with the IEEE 802.3 Ethernet standard. The KL5KUSB220

connects externally to a MII interface 10 Base -T and/or 100 Base-T PHY. The

KL5KUSB220 Controller 16-bit processor has direct access to the registers of the MAC.

UART Interface

Supports a transfer rate of 7200 to 115.2K baud.

General Purpose I/O

Up to 12 general purpose I/O signals are available. However, most GPIO may be

configured for special purpose functions such as UART, Serial EEPROM interface, Digital

Input, etc.

Serial EEPROM Support

The USB Controller serial interface is used to provide access to external EEPROM’s.

The interface can support a variety of Serial EEPROM formats.
