16/32-bit Microcontroller - Atmel Corporation

The AT91M40400 is a member of the Atmel AT91 16/32-bit Microcontroller family which is based on the ARM7TDMI embedded processor. 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 Atmels high-density, nonvolatile memory technology. The on-chip Flash program memory is in-system pro- grammable. The AT91M40400 has a direct connection to off-chip memory, including Flash through the External Bus Interface The device is manufactured using Atmels high-density CMOS technology. By com- bining the ARM7TDMI Microcontroller core with an on-chip RAM and a wide range of peripheral functions on a monolithic chip, the Atmel AT91M40400 is a powerful micro- controller that provides a flexible, cost-effective solution to many compute-intensive embedded control applications.
