Chapter 1 Overview
1.3 General Description
The SK-91470-144PMC1-MC supports the MB91470 32-bit Flash microcontroller series in
the 144-pin 0.4mm pitch package (FPT-144P-M12), like the MB91F479-PMC1.
It can be used as a stand-alone evaluation board or together with the MB2198 emulation
system using the adapter board MB2198-160 and the header board MB2198-161.
This evaluation board supports the following package: FPT-144P-M12.
The board is supplied with a socketed 10 MHz crystal as main oscillation source. Using the
internal PLL of the MCU, internal clock rates up to 80 MHz can be achieved.
Three separate RS232 transceivers are available to connect three on-chip UARTs to 9-pin
D-Sub connectors (X5, X6, X7). The transceivers generate the adequate RS232 levels for
the receive (RXD) and transmit (TXD) lines. The DTR line can be used to generate a system
reset. The RTS signal can be shortcut to CTS using the jumpers JP4, JP15 and JP19.
In-circuit programming (asynchronous) can be done via X5 (UART0).
All pins of the microcontroller except the oscillator pins X0/1 and the analog reference
voltages AVRH2-4 are connected to the edge connectors X1-X4 and are directly available to
the user. Furthermore, a 34-pin connector features all signals needed to connect an external
3-phase power stage (inverter), such as the 6ch PWM output from the Waveform generator,
as well as the analog measurement signals from the power stage. Additionally, there is a
connector for Hall sensors and quadrature encoders as motor speed / position feedback.
The on-board voltage regulator allows the user to connect an unregulated DC input voltage
of +9V to +15V to X15, or the external power stage can supply the voltage input to the
regulator. In case of any modifications of the board, or when supplying e.g. encoders or
sensors, care must be taken that the total power consumption will not overheat the voltage
regulators. Maximum additional output current for VCC is about 200-500mA, depending on
the input voltage.
There are seven 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 timer input functions as well as simple input polling. One button is reserved as
'Reset'-button for the microcontroller. Two buttons are reserved for NMI (Non-Maskable
Interrupt) and the DTTI (fault protection) function.
Eight user LEDs are connected to Port 00 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. Additional LEDs show the activity on the Waveform Generator outputs
RTO0-5 and an optional timer output.
The user potentiometers can be connected to the ADC for evaluation and application control.
The analog inputs of the 12-bit AD converter units 3+4 as well as AN2-0 to AN2-7 of the 10-
bit ADC unit 2 can be equipped with a capacitor in order to reduce noise by forming an RC
low-pass with an external or on-board resistor.
