Chapter 1 Overview

1.3 General Description

The SK-91464A-100PMC supports the 32-bit Flash microcontroller MB91F464AA.

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-100P-M20.

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 80 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, 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"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

A high-speed CAN transceiver (TLE6250GV33) 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.

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 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. Max. 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 27 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).

1.3.1 Emulator System

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 mounted:
