AT91F40816 General Description
The AT91F40816 is a member of the Atmel AT91 16/32-bit microcontroller family, which is based on the ARM7TDMI processor core. The processor has a high-performance 32-bit RISC architecture with a high-density 16-bit instru-ction 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 eight-level priority-vectored interrupt controller,together with the Peripheral Data Controller,significantly enhance real-time device performance.
By combining the microcontroller, featuring on-chip SRAM and a wide range of peripheral functions, with 16 Mbits of Flash memory in a single compact 120-ball BGA package, the Atmel AT91F40816 provides a powerful, flexible and cost-effective solution to many compute-intensive embedded control applications and offers significant board size reductions.
The Flash memory may be programmed via the JTAG/ICE interface or the factory-programmed Flash Uploader using a single device supply, making the AT91F40816 ideal for in-system programmable applications.
