Chapter 2 Hardware System
2.1 Core Board
2.1.1 Instroduction to Core Board
SOM-930-33 is a high performances core board base on iMX6 with 314 pins gold finger.
Measuring only 82 x 50mm, the small form-factor core board integrates all the requirements
for driving the iMX6DQ, such as 1GB DDR4, eMMC and power management. These make
the designer simplify to design their product, save time for their development cycle.
SOM-930-33 core board is design to used in medical equipment, industrial control, locomotive
control, data center and so on. SOM-930-33 include 2 USB2.0 high speed interface（1 USB
OTG and 1 USB Host）、2 SDIO、10 bit parallel Camera interface、MIPI 2Lanes Camera
interface、1 GBE、1 I2S、1 SATA high speed interface、2 SPI interface、1 PCIe high speed
interface、4 UART interface、2 CAN MAC、1 HDMI 1.4a output、2 channel LVDS output、24Bits
LCD Parallel output、2 I2C interface、1 SPDIF interface（no driver）and 12 GPIOs.
2.2 Introduction to Peripherals
2.2.1 7 port USB HUB FE2.1
The FE2.1 is a highly integrated, high quality, high performance, low power consumption,
yet low overall cost solution for USB 2.0 High Speed 7-Port Hub. It adopts Multiple
Transaction Translator (MTT) architecture to explore the maximum possible throughput.
Six, instead of two, non-periodic transaction buffers are used to minimize potential traffic
jamming. The whole design is based on state-machine-control to reduce the response
delay time; no micro controller is used in this chip.
2.2.2 USB to Ethernet LAN9500
The LAN950x is a high performances solution for USB to 10/100 Ethernet port bridging.
With applications ranging from embedded systems, set-top boxes, and PVRs, to USB port
Embedded Solutions Specialist

replicators, USB to Ethernet dongles, and test instrumentation, the device is targeted as a
high performance, low cost USB/Ethernet connectivity solution.
The LAN950x contains an integrated 10/100 Ethernet PHY, USB PHY, Hi-Speed USB 2.0
device controller, 10/100 Ethernet MAC, TAP controller, EEPROM controller, and a FIFO
controller with a total of 30 KB of internal packet buffering. Two KB of buffer memory are
allocated to the Transaction Layer Interface (TLI), while 28 KB are allocated to the
FIFO Controller (FCT).
2.2.3 RS232 Transceivers SP3232
The SP3222E/3232E series is an RS-232 transceiver solution intended for portable or
handheld applications such as notebook or palmtop computers. The SP3222E/3232E
series has a high-efficiency, charge-pump power supply that requires only 0.1µF
capacitors in 3.3V operation. This charge pump allows the SP3222E/3232E series to
deliver true RS-232 performance from a single power supply ranging from +3.3V to +5.0V.
The SP3222E/3232E are 2-driver/2-receiver devices. This series is ideal for portable or
hand-held applications such as notebook or palmtop computers. The ESD tolerance of the
SP3222E/3232E devices are over ±15kV for both Human Body Model and IEC1000-4-2
Air discharge test methods. The SP3222E device has a low-power shutdown mode where
the devices' driver outputs and charge pumps are disabled. During shutdown, the supply
current falls to less than 1µA.
2.2.4 RGB to VGA Convertor CH7026B-TF
The CH7025/CH7026 is a device targeting handheld and similar consumer systems which
accept digital input signal. CH7025/CH7026 encodes and transmits data through 10-bit
DACs. The device is able to encode the video signals and generate synchronization
signals SDTV format for NTSC and PAL standards and HDTV format for 480p,576p,720p
and 1080i. Analog RGB output and composite SYNC signal are also supported. The
device accepts different data formats including RGB and YCbCr (e.g. RGB565, RGB666,
RGB888, ITU656 like YCbCr, etc.). Both interlaced and noninterlaced input data formats
