2.3 General Description

The FLASH-CAN-64P-350-PMC supports 16-Bit Flash microcontrollers of the MB90350

Series and MB96350 Series.

It can be used as a stand alone evaluation board or as a target board for emulator debugger.

The evaluation board supports the following package: FPT-64P-M09 / M23

The board is supplied with a socketed 4 MHz crystal as the main oscillation clock. Using the

internal PLL of the IC, 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.

Two separate RS232 transceivers are available to connect the on-chip UART2 and UART3

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 CTS line can be

selected with jumpers (JP3, JP4, 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 UART3 (UART"B", X5) using the

Burn-In Bootloader of the microcontroller.

Two single-wire LIN-transceivers (TLE6259) are available to connect the on-chip UART2

and UART3 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.

Two high-speed CAN-transceiver (PCA82C250) are available to connect the on-chip CAN-

controller to 9-pin D-Sub connectors (X10, X11). The transceivers provides differential

transmit and receive capability between CAN-controller and CAN-bus.

If the board is used as an emulator target board, the microcontroller must be removed from

the socket and the corresponding probe cable has to be used:

Probe Cable:

MB90350 Series

MB96350 Series

Header Socket: NQPACK64SB + HQPACK64SB140

All pins of the microcontroller are connected to the edge connectors X1 and X2 and are

directly available to the user. Furthermore, the most important signals are available on the

VG96 connector (X4).

The on-board voltage regulator allows the user to connect an unregulated DC input voltage

between +9 V to +12 V. In case of any modifications of the board, care should be taken that

the total power consumption will not damage the regulator.

There are six push button switches on the board, used for Reset, External Interrupts INT10

and INT11, Trigger for Reload-Timer1 (TIN1), Input-Capture IN0 and IN1.

Eight user-LEDs are connected via a 1K pull up resistor network to Port P30-P37. If these

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

and to free the port.

Further, take care that the Portpins P00 and P01 are pulled down by N3 (10K). That is

important for in-circuit serial programming!

The operating mode of the microcontroller can be selected by the Dip-switch S2.
