The AT91M42800 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. In addition, a large number of internally banked registers result in very fast exception handling, making the device ideal for real-time control applications. The AT91 ARM-based MCU family also features Atmel's highdensity, in-system programmable, nonvolatile memory technology. The AT91M42800 has a direct connection to off-chip memory, including Flash, through the External Bus Interface. |
