Description
The AT91M63200 and AT91M43300 are members of the Atmel AT91 16/32-bit micro-
controller 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 registers result in very fast exception handling, making the device
ideal for real-time control applications. The AT91 ARM-based MCU family also fea-
tures Atmel’s high-density, in-system programmable, nonvolatile memory technology.
Both products have a direct connection to off-chip memory, including Flash, through
the External Bus Interface.
For the AT91M63200, the Multi-processor Interface (MPI) provides a high-perfor-
mance interface with an external coprocessor or a high bandwidth peripheral.
Both products are manufactured using Atmel’s high-density CMOS technology. By
combining the ARM7TDMI microcontroller core with on-chip SRAM, a multi-processor
interface and a wide range of peripheral functions on a monolithic chip, the
AT91M63200 and AT91M43300 provide a highly-flexible and cost-effective solution to
many compute-intensive real-time applications.
