Atmel Company shows the members of first a series of 400 MHz ARM926 which imbed the microprocessor which support the second generation of DDR2 for the first time, and for example build automation, the register of the data, the terminal station of sales outlet, warning system and medical apparatus are applied to industrial application.

PHY that ancillary equipment spend on slice, pairs of EBI, 10/100 Ethernet MAC, LCD, and touch-sensitive screen controller include at a high speed USB to submit to EHCI, can programme in 1.8 – or 3.3 pieces of V I/O power voltage and building of bandwidth of high data.

Jacko Wilbrink, the executive of Atmel of the arm products explains, ” Most MPUs based on embedding of ARM9 only supports SDRAM memory. The question is the period of high turnover the market of PC drives away basically nowadays taking the place of the PC out of date of memory usability and SDRAM. Compared with SDRAM, DDR2 and DDR3 offer higher memory density, high performance, lower expenses and lower consumption. That is the place where the market will go. Because of the current economic crisis, a lot of memory sellers close their SDRAM fabs. We expect the supply of SDRAM to dwindle in the future that can foresee. This causes a question for our users. ”

” While requiring the minimum outside bus of 300 MHz of DDR3 is too high to MPUs that the majority imbeds, ” Wilbrink continues. ” DDR2 is a kind of good choice of the designer’s. We believe that imbed the market, that DDR2 is destined to become memory selected on industrialized country, it is Atmel that is combining the reason why DDR2 supports in its MPUs based on ARM9 actively. Our users can move the next kind of design of theirs from SDRAM to DDR2 now, have AT91SAM9G45 and other want MPUs that DDR2 that come on make become possible soon. ”

Most MPUs based on ARM9 is developed initially with 1.8 V power voltage for the market of cellular telephone. In order to be used in the course of employing in industry, usually operate in 3.3 V, they need external motive force to manage ICs and level to move the looks device. It is managed that SAM9G45 offers the ability to combine, can programme to control in speed I/Os – or 3.3 pieces of V voltage level of 1.8, shoot and wrap up and simplify industrial management to design and reduce the expenses in 0.8 millimetres of balls.

, in 400 MHz, the twins parallel outside bus interface (EBI) because of the clock of a processor Operation Support DDR2 to be made in 133 MHz blue and combining the high speed (480 Mbit/s) EHCI submit to USB owner and apparatus port and transmitter on slice, Ethernet MAC, give MMC 4.3 with SDIO/SDCard 2.0 with two interface, and one LCD controller with resistive of audio frequency touch, reject interface CMOS camera together, SAM9G45 embedded suitable platform that employ, expect much the communication of the bandwidth, the high density data store and the modern figure user’s interface.

Systematic bus matrices and processor central memory of 12 manage part have relations, and DMA straits of 8 centres, 6 DMAs at a high speed is devoted to the video decoder, LCD controller each time, USB host and apparatus, Ethernet MAC and picture transducer interface, channel of 21 peripheral DMAs on one, pairs of EBI and little piece assign SRAM in order to guarantee continuous inside, outside datum fill minimum processors in top of the head. The high data expressway building enables SAM9G45 to carry on 100 Mbit/s + data transmission, user’s interface is offered, with the data processing concentrating in calculating.

Offer in 400 MHz and 1 V core, the typical consumption is less than 300µW / MHz. Use the alternate way, a timer of operation and 4 32 records with RTC, SAM9G45 probably consumes 8µA.

Even the transmission speed of data of several dozen Mbps is not so high as to be enough to offer the size of increase of the daily record file and complexity of the increase day by day of user’s interface. Those 480 Mbit/s USB at a high speed is offered a understanding on those AT91SAM9G45 well, the vehicle apt to use is dealing with the datum of the large quantity and connecting each other between PCBs in a system. Prove USB to AT91SAM9G45 as the driver of the host computer, SAM9G45 USB owner, to guaranteeing straightforward EHCI and OHCI standard fed through totally submits to.

Developing instrument, the trade leading supplier that OS and agreement pile totally supports SAM9G45, including Linux ration, Windows imbeds the circumference error, advisor’s figure, the technology of spider of the fine hair, QNX, Micrium, IAR, Keil, Segger, Adeneo and TimeSys.

The sample of SAM9G45 can be offered now. It is fixed the price as Q4 09 plan that 8.60 dollars with 10 K unit quantity are produced, under ordering the code AT91SAM9G45-CU.
