1.3 General Description
The
SK-91F465X-100PMC
supports
the
FUJITSU
32-bit
Flash
microcontroller
MB91F465XA.
The Starter Kit can be used as a stand-alone development platform, or with the emulation
system.
This User Guide is describing PCB version V1.1. The PCB version is printed at the TOP side
of the starter kit between Header X5 and MB91F465XA MCU [U1].
1.3.1 MCU Clocks
The board is supplied with a 4MHz crystal as the main oscillation clock for the MCU. Using
the internal PLL of the MCU, internal clock rates up to 100MHz can be achieved. The MCU
sub clock is connected to a 32.768 kHz crystal.
1.3.2 MCU Operating Mode
The operating mode of the microcontroller can be selected with the Dip-switch S1.
1.3.3 FlexRay Physical Layer
The connection to the physical layer of the FlexRay bus with 9-pin D-Sub connectors (X3
and X7) is realized with AMS8221B transceiver, it is also possible to deselect the termination
network connected to the channels. The transceivers provides differential transmit and
receive capability between FlexRay-controller and FlexRay-bus.
1.3.4 CAN Bus
Two high-speed CAN-transceivers (TLE6250GV33) are available to connect all available on-
chip CAN-controllers to 9-pin D-Sub connectors (X1 and X2). The transceivers provides
differential transmit and receive capability between CAN-controller and CAN-bus.
1.3.5 RS-232 and LIN
RS-232 and LIN signals are shared on the 9-pin D-Sub connectors (X8 and X12). It can be
selected, if RS-232 or LIN will be used. D-Sub X6 is connected to RS232.
Three RS-232 transceivers and two LIN transceivers are available, to connect the on-chip
USARTs to the 9-pin D-Sub connectors.
The RS-232 transceivers generate the adequate RS-232 levels for receive (RXD) and
transmit (TXD) lines. The RTS signal can be shortcut to CTS using jumpers (some PC
software needs this connection, when a 1:1 cable is used).
Either the DTR line or the RTS line of X1, X4 or X8 connectors can be selected to generate
a system reset.
The LIN transceivers (TLE7259) generate the adequate levels to drive the bus line in LIN-
systems for automotive and industrial applications.
1.3.6 I²C
Two additional pull-up resistors R24 and R25 can be connected to the I²C bus lines by
setting the according Jumpers (JP18, JP22).
