Chapter 1 Overview
1.3 General Description
The SK-96320-80PMC supports the 16-bit Flash microcontroller MB96320 Series.
It can be used as a stand-alone evaluation board or as a target board for the emulator
debugger.
The evaluation board supports the following package: FPT-80P-M21.
The board is supplied with a socketed 4 MHz crystal as main oscillation source. Using the
internal PLL of the KC, higher internal clock rates up to 56 MHz can be achieved.
Two separate RS232 transceivers are available to connect two on-chip UARTs to 9-pin D-
Sub connectors (X3, X5). The transceivers generate the adequate RS232 levels for the
receive (RXD) and transmit (TXD) lines. Either the DTR line or the RTS line can be selected
with jumpers (JP3, JP4, and JP5) to generate a system reset. The RTS signal can be
shortcut to CTS using the jumpers JP31 and JP32.
In-circuit programming (asynchronous) can be done via UART"A" (X3) or UART"B" (X5).
Two single-wire LIN-transceivers (TLE7259) are available to connect two on-chip UARTs to
9-pin D-Sub connectors (X6, X8). The transceivers generate the adequate levels to drive the
bus line in LIN systems for automotive and industrial applications. The LIN Vs line can be
powered by the unregulated supply input of the board, so no additional supply is needed.
Two high-speed CAN transceiver (TLE6250GV33) are connected to the CAN interface of the
MCU to allow easy connection to CAN networks.
All transceivers are fully 3.3V IO compatible to enable low voltage applications.
All pins of the microcontroller except the oscillator pins X0/1(A) are connected to the edge
connectors X1 and X2 and are directly available to the user. Furthermore, most signals are
available on the VG96 connector X4.
The on-board voltage regulators allow the user to connect an unregulated DC input voltage
of +9V up to +12V. In case of any modifications of the board, care should be taken that the
total power consumption will not overheat the voltage regulators. Maximum output current for
VCC on connector X4 = 50 mA.
There are six push button switches on the board, which can be connected to input ports of
the microcontroller. This allows the user to evaluate external Interrupts, external ADC trigger
or Input Capture functions as well as simple input polling. One button is reserved as 'Reset'-
button for the microcontroller, controlled by the supply monitor IC.
Eight user LEDs are connected to Port 6 and grounded by a 1K resistor network. If these
LEDs are not required, the resistor network can be removed to disconnect the LEDs and to
free the IO port.
Two additional pull-up resistors R42 and R43 can be connected to the I²C bus lines by
setting the according Jumpers (JP46, JP47).
