Suitable for ARM9 processor of the consumption and industry electronic product by Keith Farren
The integrated Thumb instruction set of ARM9 microprocessor, its complete characteristic contributes to the engineer while finishing advanced system design, give consideration to the requirements for multiple indexes such as chip area, listing cycle, development cost and power consumption. EP9301 has one of ARM9 processors of the price advantage very much, its highly Integrated structure and advanced design are especially suitable for various elementary and consumption and users of the industry electronic product. EP9301 has advanced 166MHz ARM920T processors, and support the memorizer Administrative units (MMU) of Linux, Windows CE and other embedded operating systems . The 32-bit microcomputer microcontroller structure of ARM920T has a pipeline of 5 grade, the power consumption that it can be extremely low offers the excellent characteristic. The data cache of 16K order cache and 16K can offer zero waiting time for Off-The-Shelf procedure and data, can also be locked, so as to ensure to the key order and machine format and undelelayed to deposit and withdraw. As to limited products of the storage size of those order, compression type Thumb instruction set of ARM920T contributes to the maximization use of utilization factor of space and external instruction storage unit. MaverickKey unique hardware programming ID is a feasible scheme of solving holding on the net and E-business safety problem. MaverickKey has offered a new method for OEM manufacturer, gives particular ID such as SDMI (safe digital music plan) to hardware Or ID that the mechanism of management of other digital copyrights used. Mbps Ethernet media access control mechanism of 1/10/100 of EP9301 built-in a high performance (MAC) ,And peripheral interface, joinable SPI, AC’97 and I2S audio interface. It is dual port USB 2.0 full-speed main machine interfaces (OHCI) of 12Mbps that this chip also has a running speed , two UARTs and a simulation voltage measurement ADC. The intersection of ARM920T and the intersection of kernel and working voltage is for 1.8V, input / 3.3V in output voltage. According to different speeds, the power consumption is from 100mW to 675mW. Industrial control, digital media server and automatic music jukebox, customer end of simple type, apparatus artificers such as set-box, POS are terminal, biometry security system and GPS device,etc. will be benefited from integrated structure and advanced characteristic of EP9301. Have the interface outside through being many kinds of, EP9301 is suitable for more apparatuses. In addition, through activating or suspending having the interface outside of EP9301, the artificer can also meet different terminal station products design requirement after it is revised that slight with the single platform, thus reduce and research and develop the cost and accelerate listing time at the same time. EP9301 characteristic is as follows: ? The intersection of 166MHz ARM920T and person who deal with -16K the intersection of data and cache and 16K order deposit slowly at a high speed and MMU can support Linux and the intersection of Windows CE and the intersection of operation and system – 66MHz department The total line of interconnected system? For only digital rights management or design IP safe MaverickKey ID – 32-bit microcomputer ID – 128 random IDs? Integrate and have the interface outside -12 definition ADC – 1/10/100 (16550 type) Mbps Ethernet MAC – dual port USB 2.0 full-speed host computer interface – 2 UARTs of 5 input ,The intersection of software and Modem support – the intersection of slow speed and interface – the intersection of SPI and the intersection of end and mouth – the intersection of AC’97 and interface – 6 passway I2C interface, IrDA of mode? External memory storage select item – 16 the intersection of SDRAM and interface, can until 2 device link – 16/8 the intersection of SRAM/Flash/ROM and interface – bunches of competent the intersection of EEPROM and interface? – but the intersection of software and real-time clock – 12 data transmission DMA passway of fine setting, can optimize systematic characteristic – start ROM – pairs of PLL can control all the intersection of clock and land – the intersection of watchdog and time-recorder – 2 common 16 time-recorder – common the intersection of 32-bit microcomputer and time-recorder – 40 Debug the time-recorder in the location? Common I/O (GPIO) -It is input / exported that 16 enhancement types with interrupt capabilities are common – use for connecting 8 extra available common I/Os of peripheral hardware? Capsulate: 208 guides the foot LQFPEP9301 and offers the designer a very large choice space in such aspects as optimum performance, integrated level and price. Can work under the environment of commercial and industrial temperature. OEM customer can fully utilize two proprietary technologies, namely MaverickKey digital copyright management tool and MaverickCrunch mathematics coprocessor. MaverickKey technology offers the new method for OEM manufacturer, can distribute the particular hardware ID for the implementation of digital rights management within the products. Already can also be adopted by OEM manufacturer and design company at the same time as MaverickKey technology of standard set in the embedded processor, protecting its product design will not be usurped while handing over production. MaverickCrunch engine is a kind of high grade mixed mode mathematics coprocessor, can accelerate in the processor nuclear and single ARM920T / double precision integer and floating point handling capacity prominent.
