The NXP analog product development boards provide an easy-to-use platform for evaluating NXP products. The boards support a range of analog, mixed-signal and power solutions. They incorporate monolithic integrated circuits and system-in-package devices that use proven high-volume technology. NXP products offer longer battery life, a smaller form factor, reduced component counts, lower cost and improved performance in powering state-of-the-art systems.
This page will guide you through the process of setting up and using the KITFS84SKTEVM evaluation board.

The KITFS84SKTEVM 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. Non-user signals, like the DC/DC switcher node, are mapped on test points. Digital signals (SPI, RSTB, etc.) are accessible through connectors. Pin WAKE1 has a switch to control them (ignition) them. A VBAT switch is available to power the device on or off.
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.

To configure the hardware and workstation, complete the following procedure:
Install jumpers for the configuration.
Table 2. Jumper configuration
Jumper | Configuration |
---|---|
J14 | connect 1-2 (connect 5.0 V on DBG pin from the USB) |
Configure switches for the configuration

Switch | Configuration |
---|---|
SW1 | open (WAKE1) |
SW3 | middle position (VBAT off) |
SW2 | 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 J14
jumper is removed.

On Windows 7 PCs, a virtual COM port installation is required. Install the Windows 7 FlexGUI driver using the following procedure.
Note: On Windows 10, it is not necessary to install virtual com port as Windows 10 uses a generic COM port driver.
The Virtual Com Port appears in the Device Manager window.
