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 highdensity, 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 computein-tensive embedded control applications.
