Description
The AT91M43300 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-performance 32-bit RISC architecture with a high-density
16-bit instruction set and features 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 programmable, nonvolatile memory
technology.
The AT91M43300 has a direct connection to off-chip memory, including Flash,
through the fully-programmable External Bus Interface.
The AT91M43300 is manufactured using Atmel’s high-density CMOS technology. By
combining the ARM7TDMI microcontroller core with an on-chip SRAM, and a wide
range of peripheral functions on a monolithic chip, the AT91M43300 provides a highly-
flexible and cost-effective solution to many compute-intensive multi-processor appli-
cations.
The compact BGA package reduces required board space to an absolute minimum.
