1 Introduction
The KITFS23LDOEVM board user manual is intended for engineers involved in the evaluation, design,
implementation, and validation of the FS2300 Body and Comfort system basis chip (SBC).
The KITFS23LDOEVM board is a soldered board supporting the FS2300 fail-safe SBC with three low dropout
(LDO) regulators.
The KITFS23LDOEVM enables development on the FS2300 Body and Comfort SBC family of devices. This
document covers connecting the hardware, installing the NXP GUI software, configuring the environment, and
using the kit. It includes guidance on how to use the registers, try OTP configurations, and burn the part.
The board as delivered includes a soldered FS2320 device with empty OTP content in order to leave the
opportunity to the user to burn the OTP configuration.

4 Getting to know the hardware
The KITFS23LDOEVM kit provides an integrated platform for evaluating designs based on NXP’s FS2300 SBC.
All FS2300 features can be accessed and monitored in a test environment using NXP GUI software to access
the registers in Read and Write mode. All regulators are accessible through connectors. Nonuser signals are
mapped on test points. Digital signals (I2C, RSTB, etc.) are accessible through connectors.
4.1 Kit overview
The kit's hardware consists of the KITFS23LDOEVM evaluation board embedded with an S32K144
microcontroller, and the USB cable required to connect the board to the PC.
The KITFS23LDOEVM evaluation board features a soldered FS2300 part and allows the user to fuse the
device’s one time programmable (OTP) feature without extra tools. Connectors, jumpers, and switches on the
board can be used to configure an evaluation environment that meets specific design requirements. The board
also contains LEDs and test points that provide a means of monitoring performance in real time. An emulation
mode allows the user to test as many configurations as needed before programming the part.
The S32K144 is soldered on the bottom side of the KITFS23LDOEVM board. The role of the S32K144 is to
manage SPI or I2C communication (depending on the user’s choice) between the KITFS23LDOEVM board and
the GUI installed on the PC. The S32K144 draws power either from the USB cable connected to the PC or from
the battery supply (when not connected to the GUI).
