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 applications.
The AT91 ARM-based MCU family also features Atmel’s high-density, in-system pro-
grammable, nonvolatile memory technology. The AT91M42800A has a direct
connection to off-chip memory, including Flash, through the External Bus Interface.
The Power Management Controller allows the user to adjust device activity according
to system requirements, and, with the 32.768 kHz low-power oscillator, enables the
AT91M42800A to reduce power requirements to an absolute minimum. The
AT91M42800A is manufactured using Atmel’s high-density CMOS technology. By
combining the ARM7TDMI processor core with on-chip SRAM and a wide range of
peripheral functions including timers, serial communication controllers and a versatile
clock generator on a monolithic chip, the AT91M42800A provides a highly-flexible and
cost-effective solution to many compute-intensive applications.
