Chapter 1 Overview

1.3

General Description

The SK-96620_350-64PMC(1) supports the F

MC-16FX microcontrollers of MB96620 and

MB96350 Series as well as F

MC-16LX microcontroller MB90350 Series with FPT-64P-

M09/M23/M24 packages.

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 the main oscillation clock. Using the

internal PLL of the µC, internal clock rates up to 56 MHz can be achieved.

Additionally a 32 kHz crystal is mounted for use as a subclock, if this is supported by the

device type.

1.3.2 RS-232 and LIN

Two separate RS232 transceivers and two single-wire LIN-transceiver are available to

connect three on-chip UARTs to 9-pin D-Sub connectors. The transceivers generate the

adequate RS232 levels for the receive (RXD) and transmit (TXD) lines. Either the DTR line

or the CTS line can be selected with jumpers to generate a system reset. The RTS signal

can be shortcut to CTS using the jumpers JP31 and JP32.

All transceivers are fully 3.3V IO compatible to enable low voltage applications.

In-circuit-programming (asynchronous) can be done via UART"A" (X3) or UART"B" (X5).

1.3.3 CAN Bus

Two high-speed CAN transceivers can be 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.

1.3.4 MCU Pins

Almost all pins of the microcontroller are connected to pin headers and are directly available

to the user. Furthermore, the most important signals are available on one VG96 connector.

1.3.5 Power Supply

The on-board linear 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 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 (colored) for the microcontroller, controlled by the supply monitor IC.

1.3.7 User LEDs and optional LCD

Eight user LEDs are connected to Port 6 and are grounded by 1k resistor network (N1). If

these LEDs are not required, this resistor network can be removed to disconnect the LEDs

and to free the I/O port.

1.3.8 Emulator System

In case of the MB963xx and 16LX microcontroller the board can be used as an emulator

target board. In this case the microcontroller must be removed from the socket and the

corresponding probe cable has to be mounted.
