Description
The AT91M42800A 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-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 applica-
tions. The AT91 ARM-based MCU family also features Atmel’s high-density, in-
system programmable, nonvolatile memory technology. The AT91M42800A has a
direct connection to off-chip memory, including Flash, through the External Bus
Interface.
