Chapter 1 Overview

1.3 General Description

The SK-91467R-176PMC supports the 32-bit Flash microcontroller MB91F467R.
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-176P-M07.
1.3.1 MCU Clocks
The board is supplied with a 4 MHz crystal as main oscillation source. Using the internal PLL
of the µC, internal clock rates up to 100 MHz can be achieved.
1.3.2 RS-232 and LIN
Four separate RS232 transceivers and four single-wire LIN-transceivers (TLE7259) are
available to connect four on-chip UARTs to 9-pin D-Sub connectors (X2-X5). 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 (JP67, 77, 87, 97) to generate a system reset. The RTS signal can be shortcut to
CTS using the jumpers JP68, 78, 88 and 98. 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 (JP69, 79, 89 and 99).
All transceivers are fully 3.3V IO compatible to enable low voltage applications.
In-circuit programming (asynchronous, synchronous) can be done via LIN-UART 0(X2).
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 / External Bus Interface Connector
All pins of the microcontroller except the oscillator pins X0/1(A) are connected to edge
connectors in functional groups and are directly available to the user. Furthermore, all
signals of the external bus interface are connected to a 96+48-pin VG connector to interface
e.g. external graphic sub-boards such as Fujitsu's 'Jasmine' sub-board.
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) resp. 1.5A (2.5V,
1.8V) 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 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.
