1.3 General Description
The SK-MB91590-208M04 supports the MB91590 FR81S 32-bit Flash microcontroller series
with 208-pin 0.5 mm pitch package (FPT-208P-M04) such as the
MB91F594BSPMC
.
The SK-MB91590-208M04 can be used standalone to develop software programs.
The on-board voltage regulator allows a regulated external DC input of 9V on X2. The
regulated outputs of the board are 5V on J1 and 3.3V on J2. Both of these output voltages
are monitored by a voltage supervisor circuit which keeps the Microcontroller (MCU) in reset
until the 5V and 3.3V voltages stabilize.
The board is supplied with a 4 MHz crystal as main oscillation. With the internal PLL clock
multiplication system the maximum operation frequency of 80 MHz for the MB91590 series
can be reached.
For software development, the board includes a single wire on chip debugging (OCD)
interface used together with MB2100-01-E Embedded Emulator (optional). There is also a
Program/Run mode switch, SW1, to select programming or run mode. One on chip universal
asynchronous receiver transmitter (UART) is available to be connected via a RS232
transceiver to a 9 pin D-Sub connector (X14) or via a FTDI-chip to a mini USB connector
(X16). The MCU Internal Flash Memory can be programmed via both connectors, the 9 pin
D-Sub connector
UART ‘A’ (X14) and the mini USB connector (X16).
One high-speed CAN interface (CAN protocol ver. 2.0) with a transfer speed up to 1Mbps is
routed out via a CAN transceiver to 9 pin D-Sub connector (X13). Alternatively, a LIN
transceiver is also routed via some jumpers to the D-Sub connector (X14).
The SK-MB91590-208M04 offers several modules for user interaction. The starter-kit has a
total of 7 push buttons: one for Reset, one for Non-Maskable-Interrupt (NMI) and 5 push
buttons
connected to MCU’s external interrupt pins. There are five Capacitive Touch Buttons
connected to A/D inputs of the MCU for touch input evaluation. Similarly, a Potentiometer
and an Ambient Light Sensor are connected to the A/D input pins of the MCU. A Rotary
Encoder provides a quadrature signal output which is fed to the pins of Input Capture Unit of
the MCU.
Eight user LEDs are connected to MCU’s General Purpose Input Output pins
(GPIO). One RGB LED can be controlled via PWM. Furthermore, a miniature Loudspeaker
is connected to the MCU via an audio amplifier circuit which takes input from the Sound
Generator module of the MCU.
For helping demonstrate the capabilities of Graphics Display Controller of the MB91F590
series, the starter-kit comes mounted with a QVGA 24bpp LCD Display. A 512Mb (64Mbyte)
External Flash Memory is interfaced to the MCU as a support for Graphics based
applications. The board also provides a video jack for Analog Video input.
Apart from External Flash Memory, QVGA 24bpp LCD Display and Miniature Loudspeaker,
all peripheral pins can be disconnected by the user using jumpers as explained later in this
document.
