Getting to Know the Hardware
4.1
Board Overview
KIT34FS6407EVB and KIT34FS6408EVB evaluation boards demonstrate the functionality of the SMARTMOS MC34FS6407 and
MC34FS6408 power system basis chips, respectively. These ICs are equipped with an intelligent power management system including
safety features targeting the latest ISO26262 automotive functional safety standard. The EVB is a standalone board that can be used
either with a compatible microcontroller or with a PC. The latter case requires a KITUSBSPIDGLEVME accessory interface board. See
Section 2.3 "Required Equipment and Software"
4.2

• IO connector (IO_0 to IO_5)
• Debug connector (SPI bus, CAN digital, RSTB, FS0B, INTB, Debug, MUX_OUT)
• Signalling LED to give state of signals or regulators
4.3
Device Features
The MC34FS6407 and the MC34FS6408 are multi-output ICs, with power supply and HSCAN transceiver. The MC34FS6407 is designed
to support up 800 mA on V
CORE
, while MC34FS6408 supports up to 1.5 A on V
CORE
. All other features are the same.
