Description
The AT91FR4081 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-perfor-
mance 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 eight-level priority-vectored interrupt controller, together with the Peripheral Data
Controller, significantly enhance real-time device performance.
By combining the microcontroller, featuring more than 1 Mbit of on-chip SRAM and a
wide range of peripheral functions, with 8 Mbits of Flash memory in a single compact
120-ball BGA package, the Atmel AT91FR4081 provides a powerful, flexible and cost-
effective solution to many compute-intensive embedded control applications and
offers significant board size and system cost reductions.
The Flash memory may be programmed via the JTAG/ICE interface or the factory-pro-
grammed Flash Uploader using a single device supply, making the AT91FR4081 ideal
for in-system programmable applications.
