Overview

The FPGA Mezzanine Card-Human Machine
Interface (FMC-HMI) peripheral board enables
developers to add a human interface to field­programmable gate array (FPGA) based
systems. The FMC-HMI provides a
development platform for customers to utilize
image capture, touch digitizer and graphical
user interface applications.

Functional Description

The FMC-HMI captures light with the Aptina
MT9D112 digital image sensor. This sensor
provides a maximum resolution of 1600x1200
at 15 frames per second FPS. The Aptina has
a 10-bit raw color depth, an I
and can utilize Bayer, RGB, and YCrCb output
formats. This image sensor utilizes an
automatic exposure, gain, and white balance
with powerful image correction algorithms,
image scaling, and a FIFO output.

Aptina MT9D112
The Aptina MT9D112 is a small (8.5mm x

8.5mm x 5mm) integrated System-on-Chip
(SoC) assembly that includes a 2Mp
complementary metal–oxide–semiconductor
(CMOS) sensor array, a fixed-focus lens with a

3.81mm equivalent focal length, and an image
processor. The sensor assembly comes taped
to the board and connects through a 23-pin
flexible printed circuit (FPC) cable.

Users can control the image processor via a
standard two-wire interface. The FMC-HMI
transfers image data via an 8-bit pixel bus with
additional synchronization signals.

provides simultaneous playback and recording
capabilities to and from a variety of sources
through standard audio jacks. Users control
the audio with a standard two-wire interface
and an I²S compatible bus presents the digital
audio.

Shanghai Tianma TM050RBH01
The Shanghai Tianma TM050RBH01 has a 5”

light emitting diode (LED) backlit thin film
transistor-liquid crystal display (TFT-LCD)
assembly that integrates a resistive touch
panel covering the whole active display area.
The TFT-LCD assembly arrives taped to the
printed circuit board (PCB) and connects
through a 45-pin FPC connector. The FPC
cable carries both the digital display interface
and analog touch panel signals.

The display interface is a straight-forward 24­bit RGB pixel bus. The support circuitry on­board the FMC-HMI provides backlight
intensity control with pulse width modulation.

The four analog signals, X+, X-, Y+, Y­comprise the X and Y plate electrodes. To
determine the touch coordinates, users must
bias the plates and measure the resistive
divider formed by the electrically charged
resistive plates using an analog-to-digital
converter (ADC) count. When operators use
the Shanghai Tianma with system boards that
have XADC support, they can use the AMS
header to digitalize the analog touch panel
signals. An on-board analog multiplexer (MUX)
switch helps users select the correct panel
electrodes for measurement.

TM050RBH01 consult the product details for

FMC support
The FMC-HMI uses a Samtec ASP-134604-01

low pin-count male connector as the main
connector for digital signals. Everything except
for the PCB dimension requirements conforms
to the VITA 57.1 specs. The connector
supports the full range of 1.8V-3.3V bank
supply voltages (VADJ).

AMS header
The AMS header is there to provide support for

the XADC feature of seven-series system
boards. Operators can use the AMS header
signals to bias the touch panel by selecting the
analog MUX inputs and carrying the differential
analog signal to the FPGA pins for
measurement.

12-pin Pmod header
A female double Pmod connector offers users

the option to connect various Pmods to the
system board. Operators can utilize the
ADG3308 auto-sensing bidirectional level
translator to level shift from 3.3V to VADJ. It is
important to note that due to its low drive
current this level translation prohibits the use of
strong pull resistors (<60kOhm) on data
signals.

Piezoelectric buzzer
A Kingstate Electronics Corp. KMTG1603-1 is

beneath the screen to provide audible
feedback for various frequencies.
