4 Getting to know the hardware
The KITFS85AEEVM 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/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.
This board 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.
4.1 Kit overview
The KITFS85AEEVM is a hardware evaluation tool that allows performance test.
The FS85xx part soldered on the board can be fused three times (see Section 7.3
"Programming the device with an OTP configuration").
An Emulation mode is possible to test as many configurations as needed. The voltage
monitoring hardware configuration is done through resistors. Note this configuration can
be changed by selecting the appropriate bridges resistors:
