1.3 General Description

The FLASH-CAN-48P is designed to support 16Bit microcontrollers with 48-pin LQFP

package like MB90360 Series, MB90385 Series, MB90455 Series, MB90895 Series, and

MB90960 Series.

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

The evaluation board supports following package: FPT-48P-M26 (7x7x1.5mm, 0.5mm pitch)

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

internal PLL of the µC, internal clock rates up to 16MHz can be achieved.

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

device type.

UART0 (only MB90360, MB90895, and MB90960 Series) and UART1 (all Series) can be

used for RS232 communication. (UART0: JP1, JP2, X3; UART1: JP6, JP8, X5)

Separate RS232 transceivers are available to connect the on-chip UARTs to the 9-pin

D-Sub connector (X3, X5). The transceiver generate the adequate RS232 levels for the

receive (RXD) and transmit (TXD) lines. The DTR line or the CTS line of the connector can

be selected with jumpers (JP3, JP4, JP5) to generate a system reset. The RTS signal can

be shortcut to CTS using the jumper JP31, JP32.

In-circuit-programming (asynchronous) can be done via UART1 (UART"A", X3) using the

Burn-In Bootloader of the microcontroller.

Additionally one TLE6259 single-wire LIN-transceiver can be used by UART1 to drive the

bus line in LIN-systems for automotive and industrial applications (JP21, JP22, X8).

If the board provides a socket for the microcontroller than it 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 used:

Probe Cable:

Header Socket: NQ048sd + HQ048sd

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

VG64 connector (X4).

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

between +9V to +12V. 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 INT4

and INT5, Trigger for Reload-Timer0 (TIN0), Input-Capture (IN0) and Trigger for the A/D-

converter (ADTG).

Eight user-LEDs are connected via a 1k resistor network to Port P30-P33 / P54-P57. If these

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

free the port. Take care of Port P30 and P31, which needs the 1k Resistor while serial in-

circuit programming!

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