1.3 General Description
The SK-8FX-TSC-32PMC is provided with a F
a LQFP32-M30 (PMC) package, as well as a FMA1125DC-24S Touch Sensor Controller
(TSC) in a 24-pin SSOP package.
It can be used as a stand-alone evaluation board or together with the MB2146-08-E BGMA
adapter.
1.3.1 Serial communication
The MB95F334 MCU offers two different USART peripherals for serial communication. The
UART/SIO offers full duplex, double buffered communication in asynchronous (UART) or
clock-synchronous (SIO) modes. The LIN-UART additionally implements the LIN protocol.
The serial interface connected to the on-board serial-to-USB converter can be selected by
solder jumpers JP16 and JP17. By default, the UART/SIO is used.
1.3.2 I2C Bus
In addition to the standard serial interfaces, the MB95F334 MCU also features an on-chip
I2C controller with a clock rate of 400kHz. Pull-up resistors (2.7kOhms) are provided on the
PCB. The I2C bus is also used for communication with the on-board Touch Sensor
Controller (TSC).
1.3.3 MCU Pins
All pins of the microcontroller are connected to standard 100mil (2.54mm) pin headers and
are directly available to the user. On-board peripheral circuits such as the TSC, LEDs and
USB can be disconnected by solder jumpers to free the corresponding MCU pins.
1.3.4 Power Supply
The SK-8FX-TSC-32PMC is by default powered by the USB connection to a host PC or USB
power supply. Alternatively, a stabilized supply voltage can be connected to the pin headers
X4 (GND) and X5 (VCC). JP3 must be opened in this case to disconnect the voltage
supplied by the USB connector X3.
1.3.5 Touch Sensor Controller FMA1125
The SK-8FX-TSC-32PMC can also serve as evaluation platform for the FMA1125 Touch
Sensor Controller. For this purpose, it offers several features:
< FMA1125DC-24S Touch Sensor Controller (SSOP24 package) with 4-8 touch input
channels and 4-8 digital I/Os (4 pins can be configured as I/O or touch input)
< Connector for up to eight touch input channels, with 'mini-slider' on PCB
< Four LEDs connected to TSC GPIO pins
The FMA1125 is connected to the MB95F334 MCU using the I2C bus. By default, the TSC is
using I2C address 0x68; alternatively it can be set to 0x69 using JP9.
1.3.6 User LEDs
The evaluation board offers several user LEDs. Eight LEDs are connected to the MCU, and
four additional LEDs are connected to the TSC GPIO pins. The LEDs can be disconnected
using solder jumpers to free the corresponding pins.
