Description
The AT91M42800 Microcontroller is a member of the Atmel AT91 16/32-bit Microcon-
troller family, which is based on the ARM7TDMI processor core. 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 reg-
isters 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 programmable, nonvolatile memory technology. The AT91M42800
has a direct connection to off-chip memory, including Flash, through the External Bus
Interface.
The Power Management Controller allows the user to adjust the device activity
according to system requirements, and, with the 32.768 kHz low-power oscillator,
enables the AT91M42800 to reduce power requirements to an absolute minimum.
The AT91M42800 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 AT91M42800 provides a highly flexible and
cost-effective solution to many compute-intensive applications.
