3. Application Example

Example of system configuration using KL5KUSB201 is shown in figure 3. To realize

the USB device application, other than the LSI, SIE PHY control and function logic are

needed.

Also suitable resistors such as Rpu, Rs and Rext and 48MHz clock oscillator or crystal

and related parts are required.

4. Pinout Diagram

Symbol block of KL5KUSB201 is shown in Figure 4. The LSI has two interfaces –

USB bus and SIE bus. USB related bus signals are shown in the left side of the

symbol block, while SIE bus signal is in the right side. SIE control signals select LSI

operation mode. These signals are FS_HSN, PU_SE0N, MODE, CRCACT, SUSPN

and RSTN. USB bus status signals are BSTAT. CRCERR and RXERR are receiving

error indicators. SIE_DAT is bi-directional bus. Signal direction and valid timing are

controlled by RXACT, RXVLD, TXACT, TXRDY and WDVLD.
