Embest SBC6045 is a high-performance ARM embedded single board computer (SBC) provided
versatile communication interfaces to meet a wide variety of applications such as industrial control,
automation, equipment monitoring, data logging, medical equipment, embedded web server etc. It is
based on the 400MHz Atmel AT91SAM9G45 microprocessor and features wide input range from 12V
to 36V with isolated power.
The SBC6045 board uses Mini6045 processor card as the CPU core board which has 256MB
(2*128MByte) DDR2 SDRAM, 256MB Nand Flash, 4MB Data Flash, 2Kbit EEPROM and integrates
UART, Ethernet, USB OTG, LCD, Touch screen, RTC and TF card slot on board. It connects to the
expansion board through two 2.0mm pitch 80-pin connectors which enables the expansion board to
access to all the core board's I/O through on-board connectors. The SBC6045 also has expansion
blocks such as CAN and SD card slot as well as a Mini-PCI slot and SIM card slot which has
integrated UART and USB signals. Customer can attach 3G module, GPRS module and other
Mini-PCI devices to this interface.
The board is capable of supporting Linux 2.6.30 open source operating system. Embest provides BSP package,
user manual and some other tools and documents to help customer with their development. It would be a ideal
platform for your evaluation and fast your development work. It can be also directly used for your design

AT91SAM9G45 combinates the function of U ser I nterface and H igh S peed D ata C onnection together,
such as LCD controller, R esistance T ouch S creen, C amera input, A udio input, 10/100M Ethernet ,High
speed USB, SDIO and so on. AT91SAM9G45 provides user with outstanding experience through
outstanding Internet and local memory media,operating at 400MHz and a number of external devices
working at more than 100Mbps.
AT91SAM9G45 play the latest DDR2 and NAND flash memory interface for program and data
storage. With a 133M internal multilayer bus interface of 37 DMA channels relative, a dual external
bus interface,and a 64K byte
distributed EMS memory which can deploy TCM, the necessary bandwidth
for maintaining the communication between Processor and High spped external device is achievable.
AT91SAM9G45 efficient power management controller clock gating and battery backup part,
AT91SAM9G45 power management controller in the power and standby mode reduces the power
consumption to a minimum.

At the same time the two ports also are used for RS485 functional interfaces, data from the CPU
is sen t out to two function al outputs simultaneously: meanwhile RS232 and RS485, the data from
RS232 and RS485 interfaces can be sent back to the CPU.
