The KITVR55-FSSKTEVM provides flexibility to play with all the features of the device and make measurements on the main part of the application. The KL25Z MCU installed on the board, combined with the FlexGUI software allows access to the registers in read and write mode. All regulators are accessible through connectors. Nonuser signal, like DC-to-DC switcher node is mapped on test points. Digital signals (SPI, I2C, RSTB, etc.) are accessible through connectors. Pin WAKE1 has a switch to control (ignition) them. A VBAT switch is available to power on or off the device.
The main purpose of this kit is to burn the OTP configuration. This kit can be operated in Emulation mode or in OTP mode. In Emulation mode, as long as the power is supplied, the board configuration stays valid. The OTP mode uses the fused configuration. The device can be fused three times. In OTP mode, the device always starts with the fused configuration, except if the user wants to overwrite OTP configuration using Emulation mode. This board is able to fuse the OTP without any extra tools or board.
Note: Due to the socket, this kit is not optimized for performance measurement or current higher than 1.0 A.
Overview of the KITVR55-FSSKTEVM evaluation board
Refer to UM11303, KITVR55-FSSKTEVM evaluation board - User Guide user manual for additional details on the featured components.
To configure the hardware, complete the following procedure:
Table 1. Jumper configuration
|J17||connect 1-2 (connect 5.0 V on DBG pin from the USB)|
Table 2. Switch configuration
|SW1||middle position (VBAT off)|
|SW3||open (OTP programming off)|
Note: At this step, the product is in debug mode and all regulators are turned Off. The user can then power up with OTP configuration or configure the mirror registers before power up. Power up is effective as soon as J17 jumper is removed.
Refer to UM11303, KITVR55-FSSKTEVM evaluation board - User Guide user manual for additional details on the hardware configuration.
The FlexGUI software does not require any installation. Unzip the folder contents to a desired location on your computer.
