Atmel ARM9-based Microcontroller

In Electronic Infomation Category: A | on November 30,2010

Atmel Corporation (Atmel Corporation) announced the ARM9-based interactive graphical user interface (GUI) microcontrollers AT91SAM9RL64, ideal for high data throughput and MAX712CSE datasheet and peripherals and MAX712CSE price and OS support for the realization of "smart" control panel applications , which provides content access features include View user manuals, video clips and MAX712CSE suppliers and audio content, and control functions for the system to provide a robust interface. SAM9RL64 only be used as a system host processor can also be dedicated coprocessor for the user interface. High-speed USB link is between the host and coprocessor AT91SAM9RL64 streaming video data to provide sufficient bandwidth.

User experience

electronic products used to control the buttons, dials and joysticks with a rapidly being replaced by touch-screen icons. Users select the icon, they will flash and zoom; users to browse the content, the icon will be moving across the screen. More and more the way the system using voice activated and can talk to and listen to users and user instructions. Interactive video content is replacing static lists and instructions.

8-bit and 16-bit microcontrollers are used to achieve cost-sensitive consumer products user interface. But not enough to deal with these cutting-edge micro-controller, interactive graphical user interface to the required capacity and data traffic. Atmels AT91SAM9RL64 is a single-chip "smart" panel solution with 200 + MIPS, 6-layer bus matrix and on-chip peripheral DMA, can support and screen updates, image processing, user interaction and dynamic create high data rates associated to ensure that customers enjoy a good user experience. These on-chip peripherals include LCD and touch screen controllers, high speed USB device, 24 DMA channels, an MCI / SDIO interface, 5 UART, one SPI, two SSC, an AC97 audio controller, 6 timers, 4 high-current driver can control the I / O, PWM, both TWI and a battery backed RTC and associated registers.

tightly coupled large-capacity on-chip SRAM to support deterministic processing

addition to 4 K bytes of data cache and 4 K bytes of instruction cache, SAM9RL64 also has an additional 64 K bytes SRAM, and through its support for the operation of handling uncertainty. This part of the SRAM in four 16 KB blocks in the form of arrangement can be configured for data and instruction tightly coupled memory (TCM), can bypass the cache to the maximum 200 MIPS clock frequency of single-cycle access operation. TCM can also be configured as local memory-chip peripherals, and multilayer bus. System startup, the SRAM is connected with the multi-layer bus, DMA controller from the non-volatile memory (such as NAND Flash or DataFlashò) key to copy the code and real time. The code mapped to the SRAM, the memory blocks can be reconfigured as TCM.

development tools and operating system support

Atmel provides free GNU gcc C compiler and GNU gdb debugger. Commercial products, such as the IAR ? (C compiler Embedded Workbench ? - real-time operating system (RTOS) - Powerware), Mentor Graphics ? (RTOS - Nucleus PLUS and the user interface middleware - Inflexion), Micrium ? (RTOS - uCOS / II) , ExpressLogic ? (RTOS - ThreadX ?) and Microsoft ? (Windows ? CE -. NET Framework), the process of being transplanted, in order to provide a complete embedded application examples. In addition, Atmel also provides a software package that provides all the peripheral register descriptions and device drivers, and various user-friendly microcontroller project examples. Atmel also provides for testing and development of the use of Quick Start evaluation board.
