1.3 General Description

2
The SK-96650_6A0_380-120PMC supports the F MC-16FX MB96600 Flash microcontroller
2
MB96650, MB966A0 and MB966C0 Series as well as the F MC-16FX Flash microcontroller
MB96380 Series with LQFP120-M21 (PMC) package.
It can be used as a stand-alone evaluation board or as a target board for the emulator
debugger.

1.3.1 MCU Clocks

The board is supplied with a socketed 4 MHz crystal as main oscillation source. Using the
internal PLL of the µC, internal clock rates up to 56 MHz can be achieved.

1.3.2 RS-232 and LIN

Two separate RS232 transceivers and two single-wire LIN-transceivers are available to
connect two out of three on-chip UARTs to 9-pin D-Sub connectors (X5, X9). The
transceivers generate the adequate RS232 levels for the receive (RXD) and transmit (TXD)
and LIN bus lines. In RS232 mode, either the DTR line or the RTS line can be selected with
jumpers (JP23 and JP38) to generate a system reset. The RTS signal can be shortcut to
CTS using the jumpers JP19 and JP36. Each of the four D-Sub connectors can be
configured as RS232 or LIN. The LIN Vs line can be powered by the unregulated supply
input of the board, so no additional supply is needed (JP28 and JP42).
All transceivers are fully 3.3V IO compatible to enable low voltage applications.
In-circuit programming (asynchronous) can be done via LIN-UART 0 and 2 (X5, X9).

1.3.3 CAN Bus

Two high-speed CAN transceivers (TLE6250GV33) can be connected to the CAN interfaces
of the MCU to allow easy connection to CAN networks.
All transceivers are fully 3.3V IO compatible to enable low voltage applications.

1.3.4 MCU Pins

All pins of the microcontroller except the oscillator pins X0/X1 and X0A/X1A as well as pin 62
are connected to edge connectors and are directly available to the user.

1.3.5 Power Supply

The on-board switching mode voltage regulators allow the user to connect an unregulated
DC input voltage of +9V to +15V, and supplies all voltages needed by the board and an
optional graphic sub-board. The regulators are rated with 3A (5V and 3.3V) and are
thermally protected against overload.

1.3.6 User Buttons

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 timer 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.

1.3.7 User LEDs and optional LCD

Eight user LEDs are connected to Port 09 and grounded by two 1k resistor networks (RN1,
RN2). If these LEDs are not required, these resistor networks can be removed to disconnect
the LEDs and to free the I/O port.
