Description
   The AT91R40008 microcontroller is a member of the Atmel AT91 16/32-bit microcontroller family, which is based on the ARM7TDMI processor core. This processor has a high-performance, 32-bit RISC architecture with a high-density, 16-bit instruction set and very low power consumption. Furthermore, it features 256K bytes of on-chip SRAM and a large number of internally banked registers, resulting in very fast exception handling, and making the device ideal for real-time control applications.
   The AT91R40008 microcontroller features a direct connection to off-chip memory,including Flash, through the fully programmable External Bus Interface (EBI). An 8-level priority vectored interrupt controller, in conjunction with the Peripheral Data Controller, significantly improves the real-time performance of the device.
   The device is manufactured using Atmel’s high-density CMOS technology. By combining the ARM7TDMI processor core with a large, on-chip, high-speed SRAM and a wide range of peripheral functions on a monolithic chip, the AT91R40008 is a powerful microcontroller that offers a flexible and high-performance solution to many compute-intensive embedded control applications.

   在IC解密过程中,对单片机本身性能特征及其加密特性与内部结构有一定的了解,能够更好的理解单片机加解密原理,选择更合适的解密方案。以上AT91R40008单片机的主要性能特征介绍,供广大客户与工程师参考借鉴。欢迎有AT91R40008解密等AT91系列芯片解密需求者与深圳芯片解密研究所联系。
